Eel and lionfish combo – 11/03/09
I plan on setting up a 180 gallon tank with somewhere around the range of 14-20,000 Kelvin lighting and plan on stocking it with a lionfish and an eel or two (that's it). After deciding a radiata lion will be too difficult, I decided to go with a volitans Lionfish.
<In my opinion the radiata is not too difficult, maybe sometimes not that easy to feed.>
As for the eel(s) I wanted to go with a ribbon eel; maybe even a mated pair. They're just too cool looking. I've read that mated pairs can help each other acclimate better to new conditions, plus they hang out together. Could this work?
<I doubt you will get a mated pair. I’ve only seen one and this was only confirmed, because they produced fertilized eggs after years in captivity. But it’s true: in small groups these eels can be easier to feed, even two are often easier than one.>
I read that ribbon eels can be quite difficult to start feeding, and volitans are aggressive feeders, so I'm worried that the volitans will eat everything before the ribbon eel(s) get(s) any.
<Yes, this can become a serious problem. You would have to add the eels first, train them to eat frozen food from a stick and only then add the lion fish.>
I plan (after weaning) to feed the inhabitants with chunks of thawed food that includes: shrimp, squid and several marine fish of which I don't remember-all from my local market. I had tremendous success with this food with my snowflake eel.
<Diet sounds good… variety is the key. Fresh food is perfect, but if you have to freeze some of it be sure to add vitamins once in a while after/during thawing.>
I really want to do a lionfish/eel tank. But I don't want a huge eel or a small lionfish.
<Zebra eels are generally easier.>
Also, what have you found from other people (and maybe your own experience) to be the best way to get ribbon eels eating?
<The best is, when the catchers and wholesalers already train them to frozen foods. They have quite easy access to small marine fishes and shrimps that compose this moray’s natural diet and can help with a smooth transition to dead food items. However, most often this is not the case and we as hobbyists or even our stores have less possibilities, less small fish species available. It would be best to buy only specimens that you have seen eating frozen foods in the store. If this is for whatever reason no option start with black mollies and live ghost shrimps. If they start vanishing, try adding a feeder stick to the tank whenever you add food. Next step would be to try a dead molly or shrimp on the stick, and then work onto a variety of other foods. In between feel free to try some of the sea food from the market – if you are lucky it might even work better than the molly route. Anyway, you will also need a little luck to have success here.>

Re: Eel and lionfish combo – 11/03/09
I'm changing from reef keeping to marine keeping so that my tank will not require as much attention from day to day. So based on the past email, would it be better just to get two lionfish instead of an eel and lionfish? If there is going to be feeding problems where the lion will get all the food before the eel does, and lionfish can't be fed too much without detrimental effects, would this route be better?
<... probably an easier choice than Ribbon eels.>
I want a lionfish more than an eel anyways.
Does the "as long as there is one cave per lionfish" rule apply with all lionfish?
<I’d tend to offer more than one cave per specimen.>
Also, can I add a volitans lion now, and then a radiata say 6-12 months later? , or would there be some issues between the two.
<I’d certainly go the other way and start with the P. radiata and add the P. volitans later.>
I know that lionfish are not normally territorial, but I'm concerned that if a lionfish has a tank all to itself, it may not get along with another lionfish that is one day suddenly added months later.
<Therefore, it’d be good to add the somewhat “weaker” species first. The P. radiata will have some time to get used to its new environment and frozen shrimps with vitamins alone, and later you can add the easier to feed P. volitans. Also see http://www.wetwebmedia.com/lions&rels.htm and http://www.wetwebmedia.com/lioncompfaqs.htm for further information and opinions. Marco.>

Lion Question, comp.  8/13/2009
Hi there. I have been reading your excellent website for over a year now and it has helped me establish my FOWLR setup. I have asked questions in the past, only to receive prompt and professional advice. So for this I thank you. Here is my concern. I have a 150 gallon setup up with plenty of LR, caves and swimming space. I currently have an Aust. Harlequin Tusk, Fox Face and a smallish Picasso. They all get along great, are eating well and seem in great health. As my final addition to the tank I would like to introduce a Volitans.
<May get picked on by the Rhinecanthus in time>
This was my plan the whole time. I am aware the Picasso may nip at its fins, but I plan to keep him well fed and keep a constant look out for any trouble, of which I would quickly separate them. My concern is this; can my other fish be "accidently" stung by the lion just by swimming around and minding their own business?
<Could, but unlikely in a good-sized volume>
Your reply, as in the past, will be greatly appreciated. Keep up the good work!
Regards,
John
<Thanks, will do. Bob Fenner>

Lionfish System: Tankmates and substrate selection. 6/19/2009
<Hi>
I just had two quick questions about lionfish.
<OK>
First, I have been doing some research but wasn't having any luck about lionfish tank mates.
<Anything too large to be eaten, and not so aggressive to beat up the Lionfish. Read here: http://www.wetwebmedia.com/lioncompfaqs.htm >
Would it be ok to keep a lionfish alone in an aquarium or would he be happier with some tank mates for company.
<Would be fine alone.>
Second question, I was thinking about a darker substrate for a lionfish setup. I know lionfish like low lighting and I was thinking that something like a black gravel substrate would not reflect as much light as the
traditional white sand for saltwater substrates.
<A few manufacturers make a dark live sand that works very well. I use it on my own tank, and it does bring out the colors of the fish.>
I appreciate your time and advise, thanks.
<My pleasure,>
<MikeV>

Frogfish/Lionfish Compatibility – 4/30/09
Hello, and thank you in advance to whoever may be answering my question today. After searching the site for hours, I decided to ask my first question. I have decided to set up a species tank for a Lionfish, to be determined as tank size allows. The tank I would prefer would be a 46 gallon bowfront. And the fish I would prefer would be a Zebra lionfish (real preference was a Radiata, but I fear a 46 gal would be too small in the long run). So the real question is; could this lionfish be housed with a Painted Frogfish (Antennarius pictus) in the same 46 gal? Maybe a warty frogfish? My girlfriend loves the frogfish and asked if this was possible.
<I would not recommend this particular combination. If your fears of the frogfish attacking the lionfish are realized it won't work out well for either fish.>
 If yes, in which order do they need to be added to ensure one does not eat the other. I was under the impression that they grow at a similar pace and I would want the frogfish to be slightly smaller than the lion at all times. I am aware that the Lion could possibly sting the frogfish, but it seems more likely that a similarly sized frogfish would devour the lion. Thank you for your time and any answers you may be able to give. It is much appreciated.
<The ultimate problem here, besides potential compatibility issues here, is the tremendous bio load that each of these animals exert, a 46 gallon tank is going to be hard-pressed to handle the waste these two produce. I suggest you consider much larger tanks, or only one of these fish.>
Andy
<Good Luck

Lionfish Question 3-28-09
Thank you in advance for taking the time to answer a few questions.  I have a 100 gallon reef tank, the man at the LFS said the Lionfish we just got should not pick at our corals, however we forgot to ask about a black slug/snail we have and a fire shrimp and another shrimp. We plan on feeding him squid as suggested on a regular basis to try and keep it form eating our shrimps/slug, however what are the odds of it not attempting to eat them or should we just take him back to the LFS first thing tomorrow?
<Hello! Next time please read through our website, these answers can be found. To answer your question, yes the lionfish will eat your shrimp(s) and possibly pick at your slug. Next time you purchase a fish it would be beneficial to research it before you purchase it. Merritt A.>

Salty Dog Question
Lionfish Compatibility 3/11/09
Hi,
<Hello Tammy>
Just wondering what hardy, personable, beautiful fish would do well with a lionfish in a 55 gal tank with sump and protein skimmer.
<Depends on what specie of Lionfish you have. The Pterois Lionfishes grow quite large and are good waste producers. If you have one of these, I would not add any more fish to your system. But to answer your question, I can tell you what likely would not be safe with Lionfish. They would be Basslets, blennies, cardinals, chromis, some species of clownfish, dart fish, dragonets, gobies, some wrasses, and Jawfish. Much will depend here on the size of the Lionfish, and the aforementioned fish, and keeping in mind that the Lionfish will grow.>
Also, what can I have to clean algae? Large snails?
<Would be fine.>
There seems to be a lot of differing opinions so I wanted yours. FYI, I really enjoy watching fish like the Lunar Wrasse that have a lot of personality and aren't shy. I used to have one many years ago but see that they need a larger aquarium than I have now.
Thanks so much,
<You're welcome. James (Salty Dog)>

Re Compatibility 3/11/09
Thank you so much for your invaluable advice.
<You're welcome.>
I wish I had found this site BEFORE I set up my aquarium. I looked and couldn't find ya'll for quite some time. I knew wet web was out there from having done research about three years ago but couldn't remember the name and my searches didn't bring you up for several months (!). Anyway...
I have a Volitans. How long will it take for him to reach adult size?
It looks like I may have to get a much larger tank.
What is a good sized tank that will accommodate the lion and a few other larger fish for their lifetimes? I hate to keep one alone.
<All on our site, Tammy. Reading here and related articles/FAQ's above, should

Lionfish and Puffer 3/7/09
I am wanting to put a lionfish and porcupine puffer in a 75 gallon tank.
<Really?>
I read on your site that the puffer will eat the lions fins,
<They can, will.>
but I also read on your site that if you get them and the lion is bigger and you introduce them at the same time they are fine together.
<Possible.>
What do I do?
<Fairly simple here, these cannot be kept together in a tank this size of tank. See:

Lion/Tang Comp  12/30/08
Great website!
<Ahh!>
I always seem to find my answers by using the Google search, but I have one I can't seem to find. I'm taking down my reef tank and will only have a 90 gallon FOWLR tank remaining. Right now the only fish in the 90 is a 6" Volitans Lion. I love my 4" Purple Tang that is in the reef tank now.
Would he be ok in the 90 with the Lion?
<Very good odds yes>
I know a 90 is too small in the long run, when I'm done with school in a year my wife has agreed to let me buy something in the 220 range.
Thanks for your help.

Dead Volitans Lion 12/27/08 Good Morning Crew... First with basic parameters and set up: Tank: 55gal SWFO, T5 HO light 36" 2 bulb 39w 18k, Crushed Coral, Eheim 2026,RO/DI...Water at tap( well) 448ppm after RO/DI 000 Livestock: 1 Volitans Lionfish, 2 Florida Condi Anemone- <Mmmm> (55 is temp tank until larger DIY tank is finished) Water before death:0 ammonia- 0 nitrite- >10 nitrate- PH 8.3- SG 1.021- O28 Water after death: 0 ammonia- 0 nitrite > 05 nitrate- PH 8 SG 1.021-O2 8 I use Salifert test kits.... I need your opinion...My lionfish died this morning and I was wondering if you can offer an opinion as to why...I do not want this to happen again, if the cause is in fact due to my ignorance...I purchased him approx. 3 months ago, acclimated for approx. 3 hours (drip method) into my quarantine tank...he stayed there for about three weeks while I tried to get him to eat... I live on the coast, so I managed to get hold of live saltwater minnows...After a few days of feeding these and silversides, I had him eating all frozen...I then placed him into my main tank with the 2 Anemones...Things have been fine with him eating silvers, frozen krill, small whole shrimp, and occasional chunk of scallop, 2-3 times a week... XMAS day, after much prodding from the visiting kids to see him "eat", I let them feed him 3 live wild caught minnows...The next morning, I noticed him laying on the bottom with his left eye cloudy...I placed him in the quarantine tank and began to start researching the net...Over the period of yesterday and today, both eyes clouded, one of his horns broke, his face became bright red, skin began falling off of eyes-face-gill area....Late this morning I noticed him darting around the tank, and he died.... I have seen several possible causes by reading ALOT of your FAQs area, but I simply can't nail it down to a cause other than poison...Maybe it is simply coincidence that this happened after eating those minnows, and he was already sick, but I have NOTHING in my tank but him and those 2 Anemones, <These are likely the root cause here> I test the water weekly, and he has been on the same diet.... I have attached 2 pictures, one from each side of his head....I would sincerely appreciate your opinion.... Thank you. Richard Gulf Coast, MS <Thank you for writing so clearly, thoroughly... the cloudy eyes, the reddening of the face. It is likely your Lionfish had a bad run-in with the Condylactis. Bob Fenner>

Re: Dead Volitans Lion 12/27/08 Mr. Fenner...Thank you for the quick response...So, basically it was my ignorance that killed this fish...He should never have been placed in the tank w/the Condi's...? <Yes... does happen. These Lions aren't very "careful" in their movements, and in the small confines or our tanks, do get "caught" cruising around in the dark...> I thought I had covered all my bases when deciding to purchase this fish...It goes to show just how much there is to learn... <Much more than a lifetime> I understand you are going to lose fish due to natural causes, but I simply don't condone losing them to ignorance, or lack of care.. <Ahh! We are definitely in agreement here. Hence my efforts with friends here to share our experiences, thoughts, speculations and accumulated facts from others> I am disabled, and therefore have a lot of free time...I have very much enjoyed reading your site since finding it the other day...I have been unable to "put it down" so to speak... <Am glad to find the work of interest, use> As for writing clearly and thoroughly, you are welcome...I consider that a simple matter of respect, especially since you are providing an invaluable FREE service...

My Lionfish is nuts, comp., reading   12/21/08
Hello -
<Hi there Deb>
I got a small lionfish from a local LFS who showed me that he was eating frozen krill.
<Mmm, hopefully defrosted!>
Ever since I got him - he is trying to eat every fish in the tank.
<Mmm, what they do>
He just made a strike at my Koran Angel - which is significantly bigger than he is. He has made attempts at all the other fish in the tank - all of which are way too big to fit in his mouth.
<Might be aggression... due to space, crowding, rather than hunger prompting this behavior>
I know that he cannot eat the Koran, but my concern is that he will somehow hurt these larger fish by striking at them. Is that something I should worry about?
<Yes... likely so... Is "stressful" to all, including you!>
My Koran does not seem particularly stressed about this - just mildly annoyed. The other fish do not show signs of stress either - they will even swim around him regularly.
<Might be... how big is this system? Of what physical dimensions? Have you read on WWM re the needs for this Pteroine and Pomacanthus sp.?>
I feed the tank regularly - and he eats, just not as robustly as before.
<... and needs more than Euphausiids for nutrition... see Lion Feeding as well...>
I can't blame the guy for trying, but I just don't want him to cause any damage to my other fish. I have kept several lionfish in the past and have never seen this kind of behavior before.
Thanks
Deb
<Some individuals are indeed more agonistic than others... Read on... Bob Fenner>

Re: My Lionfish is nuts 12/21/08
Thanks for the quick reply Bob-
<Welcome Deb>
The system is a 180 gallon 1/4 cylinder system.
<Mmm, this should be big enough... the shape may be a bit of an impediment...>
The system is set up with a bank of rock in the back with lots of caves and hiding places,
<Good>
but there is a ton of swimming room left over most of the tank. The tank mates consist of volitans lionfish, Koran Angel, porcupine pufferfish, Naso tang and niger trigger fish.
<Yikes... there may be some feeding et al. issues in time with the puffer, trigger... and this lion... The Naso will need more swimming room... or have a greatly foreshortened life span here>
I feed a mix of frozen (Rod's Food - it was recommended by my LFS),
<Is a very good food in my estimation>
ocean nutrition flake, frozen (thawed of course) krill and freeze dried Krill. I also hang a clip of Nori in there - my angel and Naso go nuts for that stuff. I soak the krill in vita-chem...should I switch to Selcon?
<Mmm, no... or maybe next time, switch to...>
I used Selcon back when I kept seahorses. I have read a lot of the posts on this forum and will be getting some silversides and squid today.
<Ah, good>
This may be a dumb question, but we bought some sushi grade salmon to use for nigiri sushi - but we don't like it. Can I feed this to my fish without causing them any problems?
<Mmm... likely so... There are generally two types of Salmon in use in sushi bars... the smoked one I'd avoid, but the "just fresh" is more than fine as a fish food>
The lion does not seem to be aggressive - he mostly displays this behavior whenever I feed the tank - perhaps the extra movement by the other fish plus the smell of the food is getting him excited.
Thanks for your help - this forum is the best source of information I have ever found!!

Lionfish (and snowflake eel) questions, comp.  ?#8364;“ 10/22/08
Hello crew.
<Hi Carl.>
I am in the process (more than a year so far...sigh) of planning my first SW tank, which will be a 90g FOWLR with a 29g sump/fuge. In the planning process, I have read Bob's original Conscientious Marine Aquarist (I gather there is an updated edition that was recently released... will add it to my "must read" list), a couple other books, and just about anything I can find on the web. Of course, I've gone and gotten myself a bit confused and am hoping you can straighten me out.
Although I can't find my copy at the moment, I seem to recall a sample stocking that I found in "The New Marine Aquarium" by Paletta for a similar sized tank was a Snowflake and a Lionfish. But I read on here you don't recommend stocking these in the same tank due to "stabbing" incidents. Can you straighten me out on this one?
<It has happened that morays have been stung to death by lionfish, which have hard, venomous fin rays. This may happen during feeding time when snowflake eels Echidna nebulosa get very exited. In return lionfish have been eaten by fish eating morays. The Snowflake/Lionfish combo is often recommended, but does not always work in the long run.>
Safe / not safe? Tank too small? Make any difference if the lion was a P. volitans versus a P. antennata?
<The P. antennata is less dangerous to a medium sized moray like the E. nebulosa and a better choice here in terms of tank size (ever seen an adult P. volitans?). Personally, I do not recommend lionfish as tank mates for morays at all.>
Also, if I went with one of those two (or both depending on your advice), what would you suggest for a cleaning crew?
<Hermits well protected against the eel with stable shells are a good choice. Urchins and starfish should also work, as will hard shelled snails. Snails with small or thin shells (like Stomatella) can be eaten by the eel. Cleaner shrimps (Lysmata spp.) are a gamble, may work (especially if in the tank prior to the fish) or be instantly eaten.>
Crustaceans are obviously out -- does that mean all cleaning crews are out? Other than the usual light and water approach, is there anything you could suggest for controlling algae?
<Yes, adequate filtration with good nitrate and phosphate reduction and giving those algae some competition with desirable macroalgae like Chaetomorpha in the fuge and fast growing easy corals like Capnella in the display.>
Many thanks, Carl.
<Welcome. Marco.>

Please save my lion fish. Anem. incomp.    8/29/08 Sir, I am in a deep trouble. I have a small aquarium and I keep a small lion and 1 carpet anemone. <!? Not compatible> This is a new fish . It was apparently healthy but within 2 days my lion is having some fungus type of thing <... nope> on his left side while the right side is clear. Can you tell me what the disease is and how to treat it. <Is a burn... from the anemone> Please see the picture for correct understanding of the problem. Please do something he is not eating and staying in one place and breathing. I have posted more pictures here please see it and then respond and help me. The anemone stung it once. I have seen it , the lion went near the anemone then suddenly shot away. http://petsconcern.blogspot.com/2008/08/please-help-sos.html Regards Babu Banik. <Need to separate these... pronto.

Re: Urgent help required. My lion is dying. 8/30/08 Thanks for your timely reply but my lion expired today and I transferred the anemone. <Sorry> Now please see the wounds of the dead lion and tell me if it was due to the anemone sting or some disease. <I would still guess the anemone, perhaps with a secondary infection.> As yesterday night the fungus was on one side today morning it was on both sides. My aquarium is small so should I keep the water and release some smaller fish after few days or throw away the water and start fresh. <I would not do much of anything besides maybe a partial water change if the other fish are ok.> Please help. <Chris>

Lionfish... comp.    6/23/08
Hello!
<Hello!>
I am hopefully soon getting a Lionfish and I was wondering about the types of fish and things that I can have in the tank.
<Check out this great 2-part article by messieurs Calfo and Fenner: http://www.wetwebmedia.com/ca/cav1i2/lionfish/keeping_lionfishes.htm >
I know that I have to get rid of the small fish I currently have in the tank.
I also have boxing crabs, hermit crabs, a starfish and a decorator crab.
I do not care if the Lionfish eats the hermit crabs.
<The lionfish would- a lion will most likely suck them down shell and all, and this would not be good for the fish>
The boxing crabs hide in little cracks in my live rock so I think/hope they'd be safe.
Do I need to get rid of the decorator crab? I want to keep the starfish if possible - its about medium to large size.
<As long as you provide the lion with other, quality foods predation on these should be limited>
I have a Tennent tang as well - do you think if i got a Lionfish that having both of those together would be too much for a 60 gallon tank?
<Ahh....yes. I hate to be the harbinger of piscine doom, but a lionfish in a 60gal just won't work long term. Keep in mind that this fish can get longer than your aquarium is deep- the poor thing couldn't turn around!>
The tang is about 5" long.
Thank you for your help!!
<No problem. Sorry to bring bad news- or give you an excuse to buy a 200gal...perspective, eh? Benjamin>

Compatibility and Design Questions Yet Again?#8364;?a Lionfish Dominated FOWLR Tank ?#8364;“ 06/16/08
Thank you very much for devoting your time, and for so long a time, to helping out the hobby by providing this service. It's truly inspirational and greatly appreciated.
<<Thank you?#8364;?we are very glad to be here/to be of service, Jeff. And you have my apologies for the tardiness of this reply>>
My questions regard fishes that I don't have for a tank that I haven't yet purchased.
<<Ah! The dreaming/planning stages are so fun, yes?>>
Every time I think that I've got a tank design settled, I read something on your site that highlights a misconception or an oversight on my part.
<<But kudos to you for researching beforehand. And do let me suggest you broaden your searching by looking to other sources along with your research on WWM. As much as we like what we say here at WWM [grin], it?#8364;™s best to not limit yourself to any ?#8364;œone?#8364;? resource>>
And thank you very much for that.
<<We?#8364;™re happy to share>>
I'd rather sacrifice time in the research phase than do it in real time with actual animals.
<<All is precious (even our/your time)?#8364;?but proper research is a ?#8364;œnecessary?#8364;? function?#8364;?and can even be quite enjoyable>>
What I've done is to decide on the fish I want to keep, then work "backwards" to figure out the system necessary to properly house them.
<<Very good?#8364;?and maybe this is obvious, but?#8364;? do also look closely at your fish selection for compatibility/suitability. I won?#8364;™t be of much use to design the system around the fish if they can?#8364;™t cohabitate>>
A Volitans Lionfish is top of the list.
<<My favorite among the Lionfishes>>
I still vividly remember walking into that fish store as a youngster and immediately standing in front of a large hex tank with a lion looking directly at me, fins splayed and being told that it was venomous. Spectacular.
<<Agreed, and if I may share?#8364;? My enthrallment with the saltwater side of the hobby began with the site of a tank chock-full of 1?#8364;? Blue Damsels against a background of white gravel and bleached-white coral (yes, I hail from the days of undergravel-filters in saltwater tanks), though I long since learned this is hardly a feasible (or responsible) display>>
Similarly, I remember seeing pictures in a book in dad's library showing a moray eel, mouth agape and full of needle-like teeth.
<<Mmm, yes?#8364;?and I remember many an enjoyable evening watching ?#8364;˜The Undersea World of Jacques Cousteau?#8364;™>>
It sent a shiver down my back. So, I would like one of those too. Since then, I have learned about and am also drawn to Tuskfish and triggers.
<<Hmm, I hope this is just a list of ?#8364;œfavorites?#8364;??#8364;?and not what you plan to keep ?#8364;œtogether?#8364;?>>
Then I read that apparently, the only way to responsibly own a trigger of any sort, is in a specimen tank.
<<Ah, well?#8364;?not exactly?#8364;?in my opinion. There are several species that can often be kept with other fishes (e.g. ?#8364;“ Xanthichthys, Rhinecanthus), but I don?#8364;™t generally suggest Triggerfishes with Lionfishes>>
Nuts! Perhaps that will be my (possible) second tank.
<<There ya go>>
Then I read that a moray and a Volitans are not a good match.
<<Depends much on the species of eel I think?#8364;?but this seems to be the popular school of thought>>
There goes the moray. Nuts again!
<<Another tank? [grin]>>
Am I okay with the Volitans and the Tuskfish?
<<Should be fine?#8364;?in a big enough tank>>
I'm now considering a Miniatus Grouper.
<<Mmm?#8364;?>>
Will that go well with the other two?
<<As long as it isn?#8364;™t big enough to eat them?#8364;?can reach about 20?#8364;? in the wild>>
Finally, I would love to have a Queen Angel, however I'm not going to be able to turn my living room into an aquarium, and they sound too aggressive for the other fish on the list anyway. Would a French or Blueface Angel work with this group?
<<The Blueface can be ?#8364;œtouchy?#8364;? or hard to keep, but given plenty of space, the French Angel would make a spectacular addition?#8364;?in my opinion>>
Given this group of four (Volitans, Tuskfish, Miniatus, Angel), will a 240g (72 x 30 x 25) suffice?
<<Yes?#8364;?though probably ?#8364;œjust.?#8364;? And it will certainly need some good ancillary filtration>>
I am planning on about 200# of LR,
<<Be careful not to overdue this?#8364;? While you will certainly need to provide some caves/dark places for the Lionfish and Grouper?#8364;?it is important to maintain lots of ?#8364;œswimming room?#8364;? as well>>
a 65g sump, ATB medium cone skimmer,
<<An interesting design?#8364;?I would be very interested in your appraisal of this skimmer>>
and a large RDSB. Am I even in the ballpark?
<<I think you are, yes?#8364;?but do also consider a canister filter for chemical filtration (carbon or Poly-Filter), as well as a fluidized-bed filter to assist with biological filtration>>
One fear I'm having is that this is getting out of control.
<<Is easy to do>>
Maybe this all boils down to: should a Volitans be in a specimen tank?
<<Not necessarily?#8364;?as long as you make your choices (livestock and setup) with this animal?#8364;™s needs/well-being in mind>>
Thanks much,
Jeff

Hey folks, My name is Jordan and I'm new to marine aquariums but I learned early on that homework is a crucially important role in the well being and longevity of your fish and aquarium.
<Hi Jordan, Pufferpunk here. Well put!>
Anyway, I've been searching all over the web and I've so far gathered only speculation not much personal experience so here goes:
Question: Are Spiny box puffers compatible with Radiata Lion fish?
<I kept my juvenile Spiny boxfish (Chilomycterus schoepfi), with a dwarf fuzzy lion in a 40g tank & they ignored each other. As far as the Radiata lionfish , are you sure you?#8364;™ll be able to find one for sale? The Radiata Lionfish is not available in the shops as often as other Lionfishes and because of this is more expensive and highly sought after by saltwater hobbyists. Radiata Lionfish are very similar looking to the Antennata Lionfish (Pterois antennata) but is distinguished by the horizontal lines on the caudal peduncle. Lionfish in general are usually fairly hardy but they do need excellent filtration and highly oxygenated water provided through the use of powerheads and airstones. My other concern would be that Spiny boxfish have a poor rate of survival in captivity, due to most coming in with severe internal parasites (needing to be treated several times to totally irradiate them) & then getting them to eat. You may have a difficult time getting your Radiata lionfish to start eating also.>
System Information: I have a 75 gallon tank with an Emperor 400 filter, 100 LBS of sand substrate (50lbs non live sand underneath 50 lbs of live sand.) 50 lbs of live rock. Will continue to add porous non-live rock. The tank is in day 6 since I've added the live rock. It is still cycling. I will cycle for about 3-4 weeks to allow for the die off to be filtered out and the ammonia levels to stabilize. My water clarity is crystal clear SG is at a stable 1.023 and pH is sitting at an optimal 8.3. Running a particulate filter and after week one I will add the carbon filter in addition to the particulate. I will add the live rock nutrients in week 2 to allow for better live rock health.
<Not necessary.>
I have a single runner light set up with a full spectrum fluorescent bulb. A foot long bubbler tube on the back glass of the tank centered behind the rock.
<A freshwater HOB filter isn?#8364;™t generally on a marine tank, unless you want to use it for chemical filtration. I suggest a good protein skimmer instead.>
What I'm thinking: Since the lionfish enjoys darker environments and the puffer fish enjoy brightly lit aquariums, I'd do a semi-opaque plastic insert in half of the bulb runner to dim down half of the tank.
<Better idea: Radiata lionfish are nocturnal in the wild and like to hang out in caves and crevices so it's a good idea to try and replicate this in the home aquarium. Create a cave with the live rock in your tank to make them feel secure. Once they are acclimated to the tank and more comfortable with their surroundings they should come out more and hide less.>
I was planning on having clown fish in the tank for about 2-3 weeks prior to adding the puffer and lionfish to ensure a
stable bio system and that the tank is well established.
<Not necessary if you are regularly testing the water. Ammonia will spike, then nitrite & after the nitrate spikes & ammonia/nitrite are 0, you can do a large water change, bringing down the nitrate & add your fish.>
If it turns out that they will co-habitate well, I will add them into the tank together on the same day. For diet I was thinking of feeding them saturated brine or ghost shrimp (I've heard ghost are equally viable for marine or fresh water) for their staple. The only thing I can think of is that the puffer would eat all the shrimp before the Radiata would have a chance to feed. Also they will grow to similar size and the other fish that I would add would generally be no smaller than 4" ideally.
<Live foods are a good start to getting these fish to eat, as this is what they are used to in the wild. You really need to get them onto more nutritious meaty (dead) foods (& crunchy foods, for the puffer?#8364;™s teeth) ASAP. This can be time-consuming, as you will have to bounce foods off a thread for each of these fish for some time, before they recognize it as food.>
Also, in the future I will be adding more porous non-live rock into the tank to create more hiding places and even add a few slab rocks to allow for caves.
<I?#8364;™d get that d?or (cave) set, before adding the fish.>
The other fish I would add into the tank would be Damsels any non-aggressive species larger than 4" to avoid them becoming din-din for the Radiata or the puffer.
<Anything smaller than the lion can become a potential dinner.>
At smaller sizes I'm sure that the 75 gallon tank would be sufficiently large to cut down on territorial disputes. I am intending to upgrade to a 125/250 gallon tank a year or so down the road also. I generally do not want fish larger than 1 foot so the community would be a large community of 4-6" fish in exception to the puffer mayhap a second stripped burr fish (which I'm positive you know is the same thing as a spiny box puffer.)
<My concern would be that the puffer can grow to a foot & will create quite a large bioload in any tank. I highly suggest plumbing in as large a sump as you can fit & include a well-functioning refugium. It is not recommended to keep 2 similar puffers together in the same tank. 1 spiny & 1 smooth (like a dogface) would be better.>
I am looking for personal experiences more than speculation. I am looking forward to the feedback, as your site is very helpful. Thank you.
<I recently had to give up my Spiny boxfish. I rescued it at a tiny 2?#8364;? & knew I?#8364;™d never have sufficient room to keep him. I have kept many, many puffers in my time & this fish was by far, my favorite of all time! The friendliest, most personable, CUTEST puffer, I?#8364;™ve ever had the joy of having in my care. He never killed any of my shrimp, snails or crabs & never was hassled by the dwarf lion. Stating that, every puffer is different. Puffers are known for their constant fin-nipping, especially of fish with long flowing fins. Be warned?#8364;? ~PP>

125 gallon FOWLR
Compatibility/Lionfish And Puffer 4/10/08
Hello:
<Hi Paul>
First let me say that you have an awesome website, I visit your website quite often.
<Thank you.>
I am currently setting up a 125 gallon FOWLR AGA aquarium and plan on putting in there a six inch Volitans Lionfish and a six inch Black Dog Face Puffer, both of which are currently in separate quarantine tanks. Is this size tank big enough for both of these fish (it will just be the two in the tank - won't add any more)? Also, is this a good mix of fish? I am also adding 100 to 110 lbs. of live rock.
<Your tank is plenty large enough for these two fish and you should not have any compatibility problems.><<Mmmmm. RMF>>
Thanks for your time.
<You're welcome. James (Salty Dog)>

Prospective 75g Set up... Lion comp.  ?#8364;“ 03/07/08
Hi WWM Crew,
<Chris>
I am looking at purchasing a 75 gallon tank that I want to set up as a FOWLR tank. The tank that I am going to buy is already completely set up and running with water, LR and all the equipment (protein skimmer, penguin BioWheel, etc.) The guy is moving away and I am just going to take
everything over. I already have a couple of 8 gallon BioCubes so I am not totally new to saltwater, but I haven't had them long either, but now I am hooked.
<Join the club!>
My question is, I would like to get some lionfish in there, how viable is maybe doing the tank with 1 Fuzzy dwarf, 1 Fu Manchu dwarf, and 1 zebra dwarf?
<Could be done>
Will they fight with each other? Second, is there a good clean-up crew that will survive these fish?
<You>
Other possible plans include 1 Russell's Lion and some other colorful active fish (any suggestions?).
<For you to read>
Can I do a Russell's Lion with a dwarf lion and maybe like one other active fish?
<Really gets too big for a 75...>
Any other suggestions on what other fish would be good in there, compatibility-wise? 75 gal. seems big to me, but I know it is not when talking SW. Still in the planning stages and wanted to get some input.
Thanks!
Chris

Snowflake eel; comp ?#8364;“ 02/29/08
Hi, my name is Jiahua
<Hi Jiahua.>
and I have a few questions concerning predatory tanks. I am a beginner in marine aquariums, but have done a great amount of research.
<Good to hear.>
My 40 gallon tank consists of
1 18 in. snowflake moray
1 sand sifting sea star
<Hope the system is old enough and has enough sand to support this star.>
I have pvc tubing for my moray and 10 pounds of live rock (that I will get more).
My question is that I saw a small 5 inch snowflake moray and a dwarf lionfish at my LFS and I was wondering if I can put either in without my original snowflake eating them.
<It may work if you are very lucky, but I certainly would not place the smaller moray in there. Small Snowflake eels in fact have been regurgitated by slightly larger Snowflakes, so they can be cannibalistic towards smaller conspecifics. The dwarf lion may be safe now, but not so 100% safe when the Snowflake is grown (have you seen an adult?). I?#8364;™m not a fan of keeping morays with lionfish, although this is done often without problems. It?#8364;™s the exceptions, when morays have been stung to death or morays have killed the lionfish, that keep me from recommending them as good tank mates. Also, I don?#8364;™t think your 40 gallon tank can take another large predator, it will get pretty small for the Snowflake alone. I?#8364;™d upgrade first before thinking about fishy tank mates (equally sized peaceful morays, a smaller grouper species, etc.). Hope this helps, Marco.>

Lionfish sting effects on fish   2/27/08
I recently purchased a small lionfish (red Volitans). I noticed yesterday that my large yellow tang swimming differently. I have very good water quality, and have been a hobbyist for 20+ yrs... I thought maybe my ammonia got a little high because of feeding the Lionfish... thus polluting more...
<Can happen>
its been day 2 and the Tang is still swimming funny... What effect does a lionfish sting have on fish?
<Are venomous to fishes as well...>
could it paralyze them?
<Might>
If stung, will the fish eventually shake it off?
<Have seen recoveries... and many secondary infections... One can hope, as well as provide optimized circumstances, nutrition...>
Thanks for your time,
Dan

Clowns and Volitans Lion, incomp.    2/22/08
Hello, a friend of mine recently passed away and left my me his Volitans Lionfish, it is rather young I would say around 8" or so. his children took
the rest of the fish and equipment).
<Hello Irwin, my condolences on the passing of your friend. The Volitans, like the one you have inherited, are stunning fish.>
My LFS would not take him, they are over stocked, I have one 55 gallon fish tank with 5 Yellow tail blue Damsels and two false Percula clowns. I have had him in this tank for 3 days but seems to pay little attention to the clowns, the other fish I am not so worried about they do not stay in one place for any amount of time. The clowns do have me growing more and more worried.
<I am too.>
They were feeding him goldies, I am trying to wean him off, the pet store said to starve him for 3-4 days and then he should start to take the frozen cubes of shrimp and muscles.
<He will switch diets in time.>
I have gotten him to eat a feeder guppy just in hopes to spare the lives of my poor clowns. At this time I cannot afford to purchase a
tank/equipment of at least 30 gallons to rehouse the clowns and their hosts.....if I keep him well fed, will he continue to leave the clowns
alone, they are still rather small, or his he a ticking time bomb. I am in a rock and a hard spot so to speak. Thanks in advance Irwin Wardly.
<Although they may coexist for a while, the odds are your clowns and damsels will end up as meals. If a fish can fit in the Lion?#8364;™s mouth, it will likely end up there in time. I have included a few links to help you out with feeding and compatibility info. Good luck, Scott V.>

Re: tank setup, Lions, sys. reading  ?#8364;“ 1/28/08
I read that already, I was just wondering what you thought would be a good addition to a lionfish tank.
<None of the choices under "Lionfish Compatibility" interest you?>
I just assumed that you would be able to make a better pick than I would. I was thinking of a Dragon wrasse because of their interesting behavior, but was concerned that they might nip at the lionfish's fins.
<Could happen, yes>
Also, I'm not sure how to introduce them both because I can only find very small Dragon wrasses that would get eaten.
<Perhaps one of these Razorfishes could be bought first, reared for a while. Are quite quick growers>
And also if I introduced them at the same size would the lionfish still outgrow the Dragon wrasse. So really, the last letter was just asking your personal opinion on interesting fish that are compatible with the lionfish. If you could just give me a few choices of species that you found good additions to tanks over the years then, I could research them and chose one that is appealing to me.
<Perhaps a Batfish/Ephippid as a center-piece? A hardy butterfly? Many choices t/here... A medium sized bass species? Bob Fenner>

Lionfish got bitten by a puffer 01/22/2008
Hey crew I like the web site very informative.
<<Hello, Andrew here. Thank you for the comments>>
I got a 29 gal saltwater tank for Christmas I let it sit and run for a week before I got any fish.
<<Did you cycle the fish tank? This process usually lasts for around 4 - 6 weeks>>
I have a aqua clear filter, a crushed coral base, undergravel filter and a single powerhead. Also a couple of dead rock, a single 2.5 lbs live rock, and various plastic plants and, a plastic log in it. I got a Volitans lionfish, a chocolate chip star first.
<<Unfortunately, the lion fish will be too big for your tank, I would advise a tank no less than 50 gallons to house this>>
Great fish love them. Everything is fine with the tank so far has had 2 water changes, and is awesome. Well now I got a black clown fish on Friday, and he is adjusting well and the lionfish don't seem to mind him either. Well today I got a puffer , big mistake there, read online that they are fin nippers, but was told by LFS that it would be ok.
<<Hmmm.. the things they will say to create a sale>>
Well unfortunately I got to watch as my lion was harassed, and eventually got a fin nipped, so my question is, will the fin grow back?
<<Providing good water quality and diet, yes>>
It is a long fin that got nipped down to the first red band. I feel so bad about it too. I have the puffer separated in a 5 gal tank am calling the LFS in the morn to see if I can exchange it for something else. But I figured if any one knew you all would any info you can give me in this matter would be very appreciated thanks.
<<Would need to know which puffer it is you have. I think your making the right decision to take this fish back for your tank size, not suitable. I would also, as mentioned above, either exchange the Volitans or provide a larger aquarium>>
<<Thanks for the questions, A Nixon>>

Re: lionfish got bitten by a puffer 01/22/2008
Hey Andrew thanks for the info.
<No problem at all Sara>>
It was a porcupine puffer, and I know the
tanks to small but will have to do for now. Here soon I'm going to get a 40 gal going and move the fish to it and set my smaller one up for a small reef tank, but eventually I will have a 50 gal for the lionfish. I named him Simba btw. I'm glad to here that it should grow back, and once again thanks for the info, its good to know you guys are here to ask, and that you know the answers to our questions.
<<We all enjoy helping and do our best, glad we could help.. Simba...hmmm...reminds of The Lion King. Convenient..>>
<<Thanks and all the best. A Nixon>>

Ambon Scorpionfish... Angler comp.    1/3/08
Morning crew! Just a quick question. Do you think that a 2 1/2" Antennarius pictus (Painted Angler) would eat or attempt to eat a 2" Pteroidichthys amboinensis (Ambon Scorpionfish)?
<Mmm, yes... have had Antennariids grab hold of my finger/s... think food/motion of such is almost or really an autonomic reaction... Like me and pizza>
Also in the tank are a 4" Gold Stripe Maroon Clown and 3" one-eyed Dendrochirus brachypterus (Fuzzy Dwarf Lionfish). I wanted to get another opinion before trying to add a fish smaller than the angler. The only reason I believe the angler would not eat the scorpion is because of just that, it's a Scorpionfish. All fish including the Scorpionfish are eating frozen foods if that changes anything. Thank you for the wonderful site! Brandon
<I'd get the Ambon up to a bit more size... like at least the same length... before introducing these together. Bob Fenner>

Cleaner Organisms 1/2/08
Hey Crew,
<James>
Is there any biological cleaner organisms I can put in my tank with a large Lionfish? I have a large Raccoon Butterfly in there with some sort of white, wormlike, burrowing parasite on his side, but I can't think of anything I can put in there that wouldn't become an appetizer.
<Best to quarantine and treat specifically for the problem.>
Or are lions smart enough not to eat cleaner gobies/shrimp/etc?
<I don't believe they care what's on the dinner table. Never saw a Cleaner Wrasse cleaning a Lionfish, not yet anyway. Maybe Bob has, but unlikely. James (Salty Dog)><<None that wouldn't be potentially inhaled. RMF>>

Meal Selection For A Lionfish/Compatibility 12/12/07
Hello Crew,
<Hi>
I had a couple questions I need to ask the experts. I have had to do some rearranging due to the birth of our first child
<A big congrats to you.>
and need some advice. I have two tanks one is a 75 gallon FOWLR and it has a Kole Tang, Soldier Fish, and Mombassae
<Pterois mombasae>
Lion fish, the other is a 40 gallon breeder Reef tank and it has (gulp) 2 Perc Clowns, 3 Blue Green Chromis, 1 Pygmy Angel, 1 Orchid Dotty back, 1 Lawnmower Blenny,1 Banggai Cardinal, and 1 Yellow watchman Goby. As you can see I have a little bit of an overstocking issue with the Reef.
<More than a little bit.>
I will be moving the Cardinal and Lawnmower Blenny this weekend to the 75 and I think I am going to try moving the Chromis as well. They are a little on the small side and I am not sure if they will be able to avoid the Lion but I think it is something that needs to be done.
<Will more than likely make a few meals for the Lionfish.>
That will leave the 2 Clowns, Orchid Dottyback, Pygmy Angel, and Goby. Do you think that would be ok?
<Pushing it a bit, but if your filtration and husbandry is up to par you could get away with it.>
Do you think I could wait on the Chromis until they are bigger too move them?
<Don't think they will get large enough to discourage the Lionfish from eating them.
Be better to trade to the LFS for store credit etc.>
Your advice is very much appreciated.
Thank you,
<You're welcome. James (Salty Dog)>

Lionfish: Tank size and compatibility (again)   8/22/07
Hello folks,
<David>
I know that this is a commonly asked question on this site, but the answers from the various WWM staff have left me confused.
I have a 125g tank (72"x18"x21") that I would like to have a Pterois volitans, a Pterois antennata and a Siganus magnificus. I'm in the process of building a sump from a 30g long tank that will house an MRC MR-1 skimmer and a refugium (plan on having 5" DSB, Chaetomorpha for nutrient removal and a Ulva or red macroalgae for feeding to the Rabbitfish). Two Mag 7 pumps for the returns and two Koralia 2 (perhaps Koralia 3s after some other advice) for water flow. I'm aiming at having a 2" DSB in the DT and about 120# of LR.
So. Doable without having to eventually upgrade the size of the tank when the fish reach full growth (relatively speaking, I realize that as long as a fish is living it is growing)?
<Mmm, yes>
Is there a more-than-slight risk of the volitans eating the magnificus once adult size is reached?
<No... should be large enough, spiny-enough to get by>
Is there room for any other residents?
<Not much fish-wise...>
I'd like to include a larger snail (tiger crowlie or conch)
<Cowry? I'd go with the Conch>
as a large form of cleaning crew. I'm trying to keep a theme to the tank (venomous - I'm a toxicologist), so there aren't a lot of other types of fish that I'm really considering.
<Though there are many other families...>
I don't like the general appearance of squirrelfish, and anything else is either small enough that it will become lionfish food or blend in with the aquascaping.
Thank you in advance.
David Kelman
<And at full size, the three will be about all this volume can handle psycho- and physio-logically. Bob Fenner>

Lion, Bass incomp.   8/2/07
Hi.. curious to see if a new addition; Leopard Grouper can be causing stress for the Lion Fish in the tank at my job.
<Yes, and yes>
I am very concerned; as I am their caretaker. We have 2 Lions Fish, Squirrel Fish, small Angel (forgot what type), snowflake eel.
<In a tank of a couple hundred gallons I hope/trust>
I have not noticed the Lions bothering or getting bothered by the Leopard Grouper; however since his introduction.. The Lion's are docile, staying in an upright position near the rocks/filter. They are also changing to a much darker burnt orange color; is this caused by stress?
<Yes>
Is there anything that can be done to alleviate the stress?
<Remove the Bass>
Usually when I come in the morning. they are happy to see me; they have not looked at me or anyone else for that matter in days. The tank is over 200 gallons with no over crowding. please help, I am so worried about them.
Thank
Nicole
<This serranid should be removed, pronto. Bob Fenner>

Re: Lionfish, bass incomp.  ?#8364;“ 08/02/07
Thanks so much, I am going to see about removal of the Grouper now; the eel does not particularly like him either; has been trying to bite the grouper each time he swims past him
I appreciate the advice.
<A pleasure to help you take good care of your aquatic charges. Bob Fenner>

Unhappy Volitans... soc. env.   6/30/07
Hello Crew!
<Ali, Darren>
Firstly may we say what a fab site you have - very interesting & informative. It is our first stop when in doubt of anything aquatic!
We have as yet been unable to find an explanation for our Volitan's problem though, so hence the query:
Bought the lionfish about a month ago, and he took a few days to settle in but soon came round. At the same time bought a porcupine puffer, trigger, grouper and leopard filefish - all small/young enough to settle together but big enough not to eat each other!
<Still... high stress... and likely problems down the line here with this mix... the Puffer and Trigger may well work the Lion woe... and good luck to it and the Filefish getting food...>
The only other inhabitants were 2 hermit crabs,
<These too will disappear>
and all were introduced into the tank on the same afternoon,
<Too much too soon my friend>
having come from the same shop and some had been sharing tanks there. We lost trigger recently - think it was scared to death by grouper as he had been harassing it.
<Yes...>
Last week or so we have not seen Lionfish eat - he has previously had defrosted silversides, krill & Mysis with the odd piece of squid, although not brave enough yet to feed from us directly, but we have witnessed him picking up pieces. He seemed to be acting a little strangely in that he was resting on the coral-sand, and making himself a shallow 'hole' by fanning the sand away with his fins.
<A bad sign>
Now though, his once prominently dark stripes have become patchy.
<This too... stress markings...>
In the past couple of days, he has developed a small luminescent lime-green patch on one side just in front of the fin, and his proud display of healthy looking 'fans' have drooped completely. In general, quite listless, breathing seems slightly more rapid and this morning he had 'wedged' himself under the edge of a piece of live rock.
Checked parameters, salinity etc - all within recommended ranges. We have tried water changes with RO and done all we can think of in respect of water quality without adding any extra chemicals/treatments. Understand hair algae should not affect him,
<Au contraire... this life can mal-affect all... and/or the conditions that pre-dispose its proliferation>
but put half dozen turbo's in to help reduce that anyway. LFS have limited range of frozen foods available, so will try to get something online - any recommendations/additives we should be on the lookout for?
<Moving this fish... to another system really. Ghost shrimp (live) would be best then to entice it to feed>
Can you give us an indication of what might be wrong & what we can do for the poor little guy? Would hate to lose him for obvious reasons.
Hope you can help
Thanks - Ali & Darren
<Could be a few things amiss... but the most glaring trouble is the placement with the other life here. Unless this tank is a few hundred gallons... I'd be moving the Lion, stat! Bob Fenner>

Porcupine Puffer stung by lionfish! 6/28/07
Hey there, <Hi Jeff, MacL here with you tonight.>
I have been using your website to research and learn for many years now and it appears I can't find any information on my current problem.
I have a porcupine puffer who would be about 5 inches, and he shares the tank with a 6 inch Picasso trigger and a 5 inch Volitans lionfish and a yellow head moray eel.. All tankmates seem to get a long most of the time with the odd argument between the puffer and the trigger, (he has never puffed up though as a result)<You know I have had my puffer for five years and haven't seen him puff up once.> however about a week ago during feeding time (which is awe inspiring to watch them all eat) <Lord I bet, I can just imagine> the lionfish had not yet engulfed his whole fish when the porcupine puffer decided it was time to get some of that fish from his mouth. Now as he swam toward the lion the puffer ever so lightly swam down onto the dorsal spines of the lion and quickly dashed in the other direction.
After about half an hour the puffer had a small ring of blood in his left eye and it eventually went away and now that one eye is cloudy. <Definitely sounds like they had a close encounter. I've seen animals recover from being stung but having personally been stung it hurts like you wouldn't believe.> He seems still relatively happy and he still has a fine appetite however he has become far more docile than he used to be. Of course he comes out a little more at night but he used to follow us around the room and now doesn't come out as often. <I'm sure he's both wary of the lionfish and wary of his tankmates since he does have an injury and possibly cannot see as well as normal. While I do not advocate medicating unless its necessary I would definitely keep an eye on his eye to make sure its clearing up on its own quickly. I personally recommend adding something like Selcon with vitamin C to assist in the cure but if the eye doesn't appear to be healing on its own you might need to consider adding an antibiotic. I wouldn't add it unless he appears to be having problems healing because it does mess with the tanks bacteria on occasion as well. >
I guess that it is cloudy eye due to the stress of being stung by the lion but just wanted to double check there is nothing I should do, as we would be devastated to lose our cute little ET impersonator!!! <To me its sounds more like he was stung in his eye because you saw the ring of blood in his eye. Usually there is a mark where they get stung. Keeping your tank healthy is the best thing you can do for your fish as you very well know. If he doesn't show signs of improvement in two or three days I would look into antibiotics for assistance. Your tank sounds lovely and amusing. Good luck, MacL>
Any advice would be appreciated..
Regards
Jeff

Large Angel Question, Compatibility; Fish Only Marine, large messy fish  5/31/07
Hey crew,
<Hi Joe.>
Kudos on all the great info (as always).
<Thanks.>
I've recently stumbled onto a piece of info on the web that concerns me and I want to bounce it off you for a sanity check since there is so much MIS-information on the web.
<No problem.>
My question revolves around stocking and compatibility.
<Okay.>
First I'll give you my tank set-up.
240g (96x24x24) w/ over 300lbs of LR, Aqua C EV-240 skimmer w/ Mag 12 pump, Dart return pump 10+ cycles per hr, Amiracle 400 dual Wet-Dry Filter, Retro PC lights, lunars, etc.
<Sounds adequate.>
Current stock list: 8" Volitans Lion, 6-7" Miniatus Grouper, 25+" Snowflake Moray Planned/Proposed List: Yellow Tang, Queen Angel, Harlequin Tusk Wrasse, and possibly a Naso or Sohal Tang (If I remove the Grouper, depends on his behavior)
<Well if you decide on going with the Sohal, you likely won't want to add any other surgeons.>
My questions are these.
<Okay.>
1. I read on another site that the Queen Angel should NOT be house with a Lion or Grouper. This was the only time I had ever heard that and I was told on another forum that the Angel would pick at the Lion.
<Is a possibility, large angels are quite territorial and despite their obvious defenses lions are much more prone to being on the losing end of a fight than most people will admit. SO I wouldn't say there is a guarantee the angel will go after the lion but it is a risk to consider as well.>
This is a SHOCKER as I currently have the 6" Yellow Tang & 6" Queen in my 75g QT tank. Can you confirm any of this info?
<See above ^^ .>
2. How does that stocking list look to you?
<You've got large and messy fish, some that are potentially aggressive/territorial. Close attention must be paid to water quality and behavior/health.>
The only one that concerns me is my Miniatus (even though he is just gorgeous). Should I be concerned?
<I would say cautious, and watching for signs of "foul play.">
I thought I would test the grouper with the yellow tang before I risk my Queen. Like a pawn in chess you know...risk the tang and protect the queen.
<Let me know how it goes.>
Anyway, thanks for the feedback.
<Anytime.>

Problems Feeding My Lionfish (Puffer/Lionfish Incompatibility) ?#8364;“ 05/08/07
Dear Bob,
<<Hello Jason...Eric here this A.M.>>
I recently acquires a Lionfish and a Porcupine Puffer.
<<Neat fishes...though not really compatible>>
My problem comes in at feeding time.
<<Indeed>>
The Puffer eats everything I put into the tank so the Lionfish doesn't have a chance to eat.
<<Just one of several reasons these two species do not do well together in typical home displays>>
Any suggestions as to how I can distract the Puffer from taking everything away from the Lionfish?  At one point the Lionfish was ready to suck in a prawn  and the Puffer practically took it out of the Lionfish mouth.  Any help would be greatly appreciated.
Best regards,
Jason
<<Obviously, the best solution is to have these fishes in separate systems.  Failing that, you can try fabricating/inserting some type of divider (a piece of acrylic sheet) at feeding times to ?#8364;œcorral?#8364;? the Puffer away from the Lionfish to give the latter time enough to feed.  Do also keep an eye on these two, especially for signs of fin damage on the Lionfish as sooner or later the Puffer will likely begin to chew on its tankmate..  Regards, EricR>>

Lionfish problems!!! HELP  3/19/07
Hi,
I have had a Lionfish for the last 6 months, who was doing wonderfully well.
In the last week, it refuses to eat, and has been swimming from side to side in the tank for hours, like he had never done before.
<Unusual behavior>
I've tried hand-feeding it silver fish, krill, and raw shrimps. He just doesn't eat.
My tank is a 92 gallon, and my lionfish is about 6 inches long. I have 3 tangs and one panther grouper.
<Mmmm>
It is a reef tank.
Is it possible that he is outgrowing the tank?
<More likely the tankmates>
Or is it the beginning of a parasite or any disease?
<Not likely>
Please help, I love this fish!
Thanks,
Gary
<The behavior is indicative of "something" bothering this specimen... that is obviously not bothering your other fish livestock... Likely the presence of the Chromileptis/Panther is "it"... If this were my Lion, I'd move it to another system to see if this "cures" the non-feeding and pacing behavior... and if you don't have such means, I'd trade in either it or the Bass. Bob Fenner>

Tank mates, SW... Triggers and Lions NOT tog.   ?#8364;“ 03/09/07
Hello all!
<<Hi Brent.>>
I have to say that I have never come across such knowledgeable and caring people when it comes to providing a home for such wondrous creatures of the sea.
<<Ah, thank you. I?#8364;™m glad to help.>>
I have been reading through all the information on the sight religiously.  I came across an article that stated one could keep a clown trigger and a Volitans lionfish together if the tank was not over crowded and provide lots of hiding places.
<<I do not personally think this is a great idea.>>
This summer I plan on getting 96x24x24 (240g long) aquarium.  The clown trigger is a must have for myself.  I was also planning on getting an emperor angelfish and a snowflake eel.  Once I read the article about the clown trigger and the Volitans lionfish living together, I though I might get a Volitans lionfish fish for the aquarium.
My question is, before I make a mistake, can I house all these fish in the aquarium?
<<I would skip the lion.>>
Furthermore, is the trigger going to kill the Volitans?
<<Clowns can be very aggressive; the lion?#8364;™s spines are certainly at risk.>>
The clown trigger would be the last fish introduced to the tank.
<<Wise.>>
If the tank mates I have chosen for the clown trigger are not advised, what could be some possible alternative suggestions?  I really would like an eel to go with the trigger as well as a large angel.  I just don't want to over crowd the aquarium.
<<I think you?#8364;™ll be fine here.  Provide broken lines of sight, and be prepared for aggression, but skip the lion.  There are dwarf lions that don?#8364;™t require mammoth tanks, if you have your heart set on one.>>
Thanks for all your hard work and dedication!
Brent
<<Glad to help! Lisa.>>

Doing What Come Naturally?#8364;?.Lion Eating Hermits 1/16/07
I have a really big problem,
<I?#8364;™m all ears?#8364;??#8364;?>
in my tank of about 450 litres, I have a Pterois volitans that have eat an hermit crab.
<Sounds like natural behavior for the lion?#8364;??#8364;?.>
I am very worried , he seams to be ok (to days later)
The hermits are from Brazil, very small ones, I have more or less 20 hermits crabs in my tank and about 20 snails too. Can my scorpion digest it?
<If he was large enough to swallow it whole, he should be able to digest it just fine.  In fact he will continue to eat the rest of the hermits and snails.>
will he die for eating it?
<Not likely.>
Please tell me what do you think it will happen.
<I think your lion will continue to practice this natural behavior on smaller tank denizens.>
The Pterois is about 15 centimeters long and 43 years of age.
<I?#8364;™m guessing that age is a typo or was lost in translation somewhere?#8364;??#8364;??#8364;?.>
Thank you very much from ARGENTINA (SOUTH AMERICA)
ALEJANDRO
<Adam J. from SoCal.>

Re: Lion eating hermits
Thanks a lot, I was not sure if he could digest the hermit, you were right, the age of my lion is 4 years,
<That's what I figured....>
I usually feed him with shrimps, fish meat, and beef heart.
<Leave out the beef heart...terrestrial food isn't that great for him.>
I did not know that it was usual food (snails and hermits),
<Lions are ambush predators, if it fits into their mouth it's fair game.>
so next time I will not collect that poor bugs from the sea, at least I can say that it will be good for her diet.
<Somewhat, variety is the key IMO.>
I brought them thinking of a cleaning team.
<Understood.>
Here in Argentina all kind of stuff from overseas is extremely expensive, and our economy is not the best.
<Sorry to here that.>
In my tank I only have the lion and a zebrasoma velifera , with a wet dry , and a canister filter and to more pumps.
Thank you very much again and I should congratulate you for you job

Re: Sohal tang aggressive?  1/2/07
Thanks for the prompt response Rick.
<Thank Graham for pestering Rick, Rick for the info ;) Graham with you exclusively today.>
My Damsel is 1" and was the first marine fish my wife and I bought 1.5 years ago.  He's a warrior!  The Lionfish gave up hunting him a long time ago.
<Sounds about right for a Chromis xanthurus.>
I had intended to add a 3" Sohal, so you and I are on the same page except for one thing.  I intended the Sohal to be the next, but not last addition to the tank.  
<Can be done... but you save stress and returns to the LFS when adding an aggressive fish to your system last.>
I'd also like to get an Angelfish (not sure what kind. I'd like to get a larger specimen), and a Porcupine Puffer.
<You're right to add them before the Acanthurus sohal.>
So... to revise my question, would a Sohal Tang be a good, last addition to my tank if I had...
Volitans Lionfish 9"
Harlequin Tuskfish 5"
Yellowtail Damsel 1"
Porcupine Puffer ?"
Angelfish ?"(any suggestions?)
<Honestly, I think your specimen list would be fine, though I keep thinking of all the Volitans I've seen bullied by other fish in the past. But if your's eats live food, then maybe he has the Moxie he needs. As for the angel suggestions, try a Pomacanthus paru (Cortez) or Pomacanthus conspectus (French) as these are hardy, active and feisty individuals. Just know that tangs and angels sometime decide they are too similar to be nice to each other. You may want to consider adding the angel and tang at the same time to avoid territorial disputes.>
Do you think this bioload would be too high?  I have a 40 gal refugium as well as the EV240, I fill a Phosban reactor full of Carbon, and do 20 gal water changes weekly with RODI water.
<Nope, looks good to me.>
Thanks for the warning on the poisonous spines.  You are exactly right, not a whole lot is written about this topic.
Happy New Year!
<And you.>
Wayne
<Graham>

Re: Sohal tang aggressive?  1/2/07
Thanks Graham!
<Of course! Just happy to help.>
I understand your concern for the Volitans.  If the new fish I introduced were smaller than my lionfish, would that deter them from bullying him in the future? ...even if they get bigger than the lionfish in the future?
<I did not mean to cloud your mind on the subject of your lion. No, he is not generally going to get beat up. But, they do tend to take the path of least resistance in an overly aggressive setup. I don't think this will be the case, and you have the right idea about starting the fish small so they remember him as bigger. Besides, a tang has little to gain from dancing with a Lionfish. Groupers and other medium to large aggressive were on my mind. I did not know that Lionfish have a history of being bullied.  Always thought they were tough, but passive fish.
<True, see above. (I left the retail store I worked in one night to return the next morning to a 300gal tank strewn with Lion spines and guts that had been painstakingly spread about by a 6" Balistapus Undulatus. Poor buggers.)>
Wayne
<P.S. one thing I forgot to mention, is that the small list of angels I mentioned is obviously not the end-all. Just a quick list I came up with based on a little looking at some various online databases and my memory of their reactions in a retail or service setting. Generally, angels that are hardy, are usually tough, too.>

Re: Longnose Hawk compatible with a smaller Lion and Snowflake Moray?   12/8/06
Thanks Bob.
<Welcome David>
If I am looking at a Radiata or Antennata Lion... They get to a maximum of about 8 - 10", correct?
<About this standard length in captivity, yes>
If I get a young lion and a medium sized Hawkfish... Both should be around 4-5" ????
<Mmm, the Lionfish will likely be around this length minimally, the Hawkfish almost always smaller at sale>
  Would/could a 10" lion swallow up a 4 or 5" Hawkfish...
<Oh yes...>
Aren't they quite long?
<Lionfishes regularly ingest fishes (and non-fishes!) of considerable size... Shades of the old-saying/pitch, "I can't believe I ate the whole thing">
  I guess obviously you're implying quite likely.  Would a Flamehawk be better?
<Mmm, not in terms of relative potential for being consumed, no, not IMO/E>
They are thicker and chubbier aren't they?
<Heeeee! Are you (giving you my best Robert De Niro impression while doing a push-up here) talking to me? Yes, are, but still imminently-inhaleable>
I put a deposit down on my snowflake moray.  This one's beautiful...
Retailer has had him for 5 weeks.  Putting my fingers close to the tank, the eel comes to investigate, seems very alert, and healthy.
<Good sign>
  I saw him full length at about 13".  This will be my first addition to the 200gallon tank and because he is the first addition I am more or less quarantining him in my display.  All other additions will be quarantined in a hospital tank.  I'm wondering if it'd be worth it to add one or two blue-tailed damsels just to ensure my Moray isn't a fish eater?
<Mmm, a good idea to add these, and/or other life period... principally to help "clean up" uneaten foods, "detritus"... and keep your interest...>
Or do you think not necessary?
<Not as a test for the Eel's compatibility, no>
I'd rather a $6 damsel be eaten up vs. a $50 show fish.  Furthermore, given my tank volume... Am I ok introducing two fish at once initially?
<Mmm... in terms of? I would at least dip/bath the new fishes...>
Or should I stick to the eel with the next addition after about 3 to 4 weeks?
<Up to you>
Given my snowflake Moray, the radiata or antennata lion (only one of), tang, a smaller angel or flame angel...
<A/the Lion may well eat the Centropyge in time as well...>
Can you recommend a few others that would be a nice addition?
<Posted on WWM...>
You questioned my selection of wrasse (ornate wrasse) as a possible bully to the lion?
<... what species is this? Halichoeres ornatissimus? The common name is applied to a few labrids...>
But your FAQ and website almost imply that this wrasse would be a good community fish only specimen.  I'd like a colorful wrasse that doesn't get bigger than about 6-8"... Or at least out of the swallowable range from the lion.
By reading your info... I'm definitely staying away from puffers and triggers.
<You are wise here if you intend to keep Lions, Eels...>
  A Marine Beta perhaps?  Foxface?
<Both good choices>
  What I'd really like is your opinion on another addition that maybe I wouldn't even think of...
Something out there in left field so to speak.  I like colorful critters.  Would a lynchia star be ok?
<Not a Linckia... believe/trust me here... take your time... You have plenty... Enjoy the (non-western ethic I know) process (not simply an end-point/product) view/experience here... Read, imagine, visit LFS's, chat with other hobbyists... Bob Fenner>

Re: Mixing in a Moray - 11/02/06
Hi Bob,
<<Eric here, stepping in for Bob who as you might be aware, is out diving the globe with "off-again on-again" net connectivity>>
Thanks for the reply.  Was also wondering if a 210 would be too small for a Tesselata or could he live comfortably in it even when he reaches full size?
<<Would be fine for a while, but these eels can exceed 10 feet in length (becoming very aggressive in the process)...it would warrant more than a six-foot tank at maturity, in my opinion>>
Also how do you find puffers (dogface in particular) get along with lions?  Some people say they do great and others say the puffers just chew all their spines off and beat them up.  I know puffers like to pick at things but in general do they get along together with lions?
<<Not a good mix.  I see many instances where hobbyists are having problems with lionfish, and lo and behold, there's a puffer in the tank>>
Thanks again for any info you can help me with.
<<Pleased to share.  Eric Russell>>

Lionfish in a Reef - 09/16/06
I have a question in regards to adding a lion to a reef tank.
<<Okay>>
I know I don't have to worry about the lion messing with corals but how about my clean-up crews?
<<Is some danger of this>>
This is a 90 gallon reef by the way with about 120lbs of live rock.  I know shrimp will be inhaled, but how about hermits and
starfish.
<<Not usually bothered>>
Also, about their behavior.  I have been told that Dwarf lions are not as active swimmers as say a Volitans.  Is this true or false?
James S. Smith
<<None of the lionfish species are what I would call particularly "active".  All are generally slow-moving "stalkers" that tend to prefer calmer and less brightly-lit portions of the reef.  The Volitans lionfish will usually remain "suspended" in the water column, while the Dwarf species is often found "at rest" against the rockwork, usually in a vertical head-down posture...in my experience.  Eric Russell>>

Lions and Marine Bettas 7/1/06
Hi there just a quick question.  Would a marine betta be O.K. with a zebra lionfish in a 30 gallon tank.
Many thanks.

New to the hobby . . . a little advice ... MacL's Back!!!
Hey To all of you at WWM! <Hi there, MacL here after a long hiatus.>
The hobby of fish keeping has just recently became a very serious interest of mine, I housed a few 10 gallon tanks for years but just recently
increased my tank sizes... alot. <Beware it can become seriously addicting.> I am still living at my parents house, because I just graduated from high school, so my room has became the show room for my two aquariums. I have a 46 gallon bowfront FW tank and a 55 gallon SW tank. <Very nice.> I have a picture attached to give you a better idea on the
situation. <Unfortunately the picture didn't make it to me. Sorry!> The floor seems to be holding these two aquariums fine. I searched on your FAQ's on aquarium stands and floor support and found that the type of iron stand supporting my 55 gallon should have a piece of plywood under it!!! <The plywood spreads the weight and basically, for lack of a better word, cushions it. It also provides bracing so the legs don't bend and fail on you. Always a good idea to prevent a problem.>  I would drain my tank and get right on that but I plan on taking the 46 and 55 out of my room and just keeping a 125 gallon aquarium with a nice level wood stand. My parents seem concerned with this (which is understandable) but it is only 25 gallons more of weight. <It is indeed just a little bit more weight but it does have a little to do with weight disbursement. What you also need to remember is that water weighs 8 lbs per gallon so when you figure 125 gallon you have around 1000lbs of weight. Most people do not have the support beams in their house to hold that and need to do some additional bracing unless they use a load bearing wall.> I do not see this being a problem as long as the weight is equally distributed. I am hoping you guys can help me out because the only reason for upgrading to a 125 is from all of the useful information I found regarding proper tank sizes for fish. <Absolutely the way to go, the larger the tank, absolutely the better for many, many reasons.> My local fish store which does strictly saltwater fish convinced me that a baby striped pufferfish (around 3 inches) and a large lionfish (around 7 inches) would do just fine together in a 55 gallon tank! <EEEEEKKKKKK.>
I don't want my poor animals growth to get stunted from such a small tank.
My striped Pufferfish has been very stressed since I introduced the lionfish. <Not surprising, have you seen the size of the lionfishes mouth? Reminds me of some people I know digging in at the local buffet.> The lionfish seems territorial but has never attacked my little friend. All my puffer fish does now is lay on the bottom hiding in openings of live rock except for when food is dropped in at nights. I honestly think that the only reason for this is that fact that the tank is to small and extremely over crowded. I searched and found the striped puffer fish can reach 15 to 20 inches, is this in captivity or in the wild? Again the big question I have really concerns my floor supporting the weight of a 125 gallon. With a sturdy stand and foam or ply-wood underneath I hope it would not be a concern, if so could you please point me in the right direction of what to do for it to work. <Are you on the first floor or the second floor? That makes a huge difference!> The house is probably a little over 25 years old. My Local Fish store said a tank of 180 gallons would be fine in my room because the weight would even out to be around a pound to each square inch... I trust your advice much more than theirs especially after they sold me those animals knowing I had such a small tank. <I have to say that it really depends on the location in your house. Where you plan to put the tank. If it won't work in the location you planned perhaps some negotiations with your parents. Do you have a basement?> I learned my mistake and do all my research on WWM now, thanks a lot guys. Also in the past I have emailed to you, I found a few of my messages answered but had trouble searching and finding the rest of them, I think this is because I was new to the site and didn't know where to find them. I am pretty sure I have it figured out now though, do I click on the "today's FAQ's page?" I figure I do although I didn't see a special section for the Saltwater FAQ's. Just Fresh and Brackish. <Look under Marine.>
Also to give you a better idea on the setup of my room for the support of a 125 I took a picture which includes the 46 gallon bow front (left side) and the 55 gallon Saltwater (right side). Both are on the same wall. And a picture of my very large lionfish as well if you had any interest in seeing it! I picked him up pretty much full grown for only 30 dollars.. The guys at the LFS enjoy my company there and sell me fish extremely cheap. <That's a good thing and a bad thing when they sell you a fish that doesn't work for the size of your tank. Obviously though you are on the right track.>
Again thanks for taking the time to read through this email and answer my questions! Do you guys get paid to do this ? I hope so!  <Nope no payment. Good luck. MacL>

125 Gallon Aquarium - Proper Fish Selection   5/23/06
Hello everyone.  I have a question about the proper selection of fish for a 125 gallon tank (4'x2'x3') with 100 lbs of live rock, wet/dry and a Vecton 15watt UV, no crustaceans, no coral.  My dream list of inhabitants would be a P. Volitans Lionfish, Emperor Angel, and a Powder Blue Tang.  
<The angel will grow too large for this size, shaped system>
The more I read, the more I'm finding that my tank is probably not big enough, especially for the Emperor.  The only fish that is a must-have is the Lionfish.  Can you give any suggestions as to other fish that would be compatible?
<... there are many. Please read here: http://wetwebmedia.com/lioncompfaqs.htm
for guidelines, suggestions>
Possibly a Huma Huma Trigger (might nip at the Lion?), a dog-face puffer or a long-nose butterfly?
<Perhaps the last... puffers and triggers are too likely to chew the lion. Bob Fenner>
  Thanks for all the help!
Ryan Mullinax
Thanks Bob!  I just want to say that I have gotten so much insight from WWM
and I feel much more confident with keeping marine aquaria now.
<Ahh! Glad that you have found our efforts useful. BobF>

Puffer and red Volitans   03/07/06
Hello, I have spent many countless days/nights searching through your site, and i believe now it is unavoidable* (at least i think it is) but to
ask you the ?  is there anyway i can keep my porcupine puffer with a Volitans lionfish. 
<Not a good idea. Have seen done (successfully and not) many times... but two real problems. One that the Puffer might bite (but good) the Lion, and more commonly that the Lion will have great difficulties feeding with the Puffer there...>
I personally did not choose the combination but my wife who went to a certain (very educated I must say, educated as most common betta owners) LFS name specific PetCo,
<"It's the people, not the store name">
no need discriminate etc., but anyhow i have a Volitans with a porcupine and i am wondering if there is any way that i can make them coexist, i understand its the porcupines
nature to nip at long fins, so i am looking for a way to sell the Volitans, or provide a comfortable (safe) environment for both of them.  The tank that the Volitans and the porcupine are in is a 75 gallon
<Will ultimately be too small for either>
with a divider in the center (estimated 37.5 gallons each) far to small for each of them individually. In other words what actions can i take to give them a happy environment?
<Really? Two larger tanks... see what we've both written above>
(in addition i have tried to sell the Volitans but there is not a high demand in my area) any help/suggestions appreciated

Lionfish help ... Centropyge comp.  - 3/1/2006
Hello Bob
<Wayne>
I read until my eyes dried out trying to find the answer to my Lionfish question.
<Google on WWM, the cached view...>
So forgive me if I'm asking a repeat question.  I have a 120 Gal, that I upgraded to from a 55gal, with about 50-60# of live rock, Volitans
Lionfish, Snowflake eel, Coral Beauty, 2 Yellowtail Damsels.  I also have 2 Condy Anemones, Devils Hand Leather, Cauliflower Leather.  I'm using a
Berlin Skimmer, Orbit 4x96w 10K/Actinic lighting (switched from a Coralife 4x65), a 40 gal refugium with a mag18 pump.  I have a small powerhead that I
use to keep circulation going behind the rocks.  So far I've only tested for Nitrates, Nitrites, Ammonia, and PH, which are a 0,0,0,8.2 respectively.
<All sounds good thus far>
I just added the Berlin (5days ago), and was using a Skilter prior.
<Heeee! Some difference now!>
  I've had this tank running now for about 7 weeks (upgraded from a 55gal which I had for 1 year).  We've had the Lionfish now for about 7 months.
Here's my question/concern..
My Lionfish has recently (past 2 weeks, since we introduced the Coral Beauty) started to be extremely active.  This is just the opposite of what I'm used to.  
<Yes... Centropyges can "pick" at Pteroines mercilessly...>
He usually hangs out in some "caves" I made for him, and was relatively inactive during the day.  Ever since I got the Coral Beauty, the
lionfish no longer goes to the bottom half of the tank and is constantly facing the glass and swimming against the current.  He is eating well (I
feed him a combination of frozen shrimp, scallops, and flounder every other day), and his black stripes are now slightly brown.  I noticed one of his
eyes looks slightly "cloudy".
<Good observation>
It's so subtle that I'm questioning whether or not I'm just being paranoid.  Paranoid or not, he is definitely more active than I've ever seen him.  Today, I restructured the "seascape" and made more caves hoping that he'll get back to normal. Should I be concerned about this energetic behavior from my Lionfish, or am I being paranoid.  He has never been this active before. Thanks again for all your help!

<Only time can tell whether the Dwarf Angel is directly pestering your Lion... If so they will have to be separated. Bob Fenner>

Re: Lionfish help **Time sensitive feedback. Please!!!   3/3/06
Hey Bob!
<Wayne>
Thanks for the feedback...
<Welcome>
I have to say... I stare at our tank probably more than I should, and I've never seen the Coral Beauty and the Lionfish act aggressively toward each other.
<I see>
So I'm thinking that an Ich outbreak is starting in my tank...and thus the reason form my Lionfishes "hyperactive" behavior.
<Maybe>
The Lionfish's' condition hasn't changed and my wife noticed this morning that the Coral Beauty has some white spots on it.  Again, it's kind of
subtle... we at first thought they were just air bubbles, but after most of the day, the spots remained on the fish.  You see... I got bit by the bug
when I got the 120gal, and only now have I discovered that QT'ing newly bought fish is a necessity.  Needless to say, the Coral Beauty was not QT'd.
My tail is between my legs, and I've learned my lesson.
<Good>
So...We've decided to start a hospital tank.  We figured that it was better safe than sorry.  I've never seen Ich before, so after reading all the
symptoms, white spots, cloudy eyes, sporadic behavior... we figured we fit the bill, and that it was a good idea to start a Hospital tank.  
<There are some pix on WWM, elsewhere on the Net... I'd look>
Here's what I plan to do or have already done.  Please tell me if I'm doing something wrong.  This strategy has mostly been sourced from WWM...I've
never done this before so here goes...
I took our old 55gal, and mixed salt water with distilled water (I don't have enough water pressure for an RO/DI unit).
<I would use the "old water" for the initial move here... no reason not to>
The manufacturer confirmed no copper in the distilling process, and no copper present in test results.
My main tank is usually around 1.023.  I'm going to mix the hosp tank to 1.021.  I hope this isn't too low.
<For these fishes? No... but I would not move them to more than 0.001, a thousandth change in a day...>
  I'll let the water mix for a good 24 hours.
<Do this for the needed change-out water... not the initial. Make this with the current system water with some freshwater added to lower the initial spg about a thousandth down...>
A 280gph powerhead will be inserted, a 300w heater to match the main tank @ 78 degrees, and a Skilter with no carbon, just the foam filter
inserted (I also disabled the "skimmer" part of the Skilter).  I don't plan to use any lighting, just regular day light.  I have a Coralife 4x65 10K/Act
light just sitting in the garage that I could use. I plan to add some CopperSafe by Mardel...how much?? I'll wait until I see the directions from the bottle.
<... Very important to hammer this message home... USE a test kit... NOT a blind measure of so much per supposed gallons...>
When all is mixed, and at least 24 hrs have passed from the time I salt-mixed the hospital tank, I plan to take ALL my fish out (regardless of
their symptoms or lack of), and freshwater dip them 3-5 min each.  I can't find any Methylene Blue to mix in the dip, I hope this isn't too big of a deal!  
<Shouldn't be if they're not "too" debilitated... do pH adjust...>
So I will use just distilled water.
<Dechloraminated tap is fine, better... and do aerate this...>
As sad as it is to say, I can't afford to pay $29 to overnight a bottle of the stuff to my home.  I've spent all my disposable cash on the main tank.  From there they will go into the
hospital tank for 6weeks.  I'll do 10% water changes and siphons every week for 6 weeks, as well as my main tank. After the 6 weeks, do I just drop all the livestock back in the main?
<Likely so>
Is there a way to check the main tank to see if the ich is gone?  
<Not practically>
The livestock that will go in the hospital tank are... Volitans Lion 7", Coral Beauty, 2 Yellowtail Damsels, and a Snowflake eel 8"
<The damsels will likely be inhaled... do add some large PVC fittings, pipe for hiding>
This is where I get cheesy! I have a plastic "Castle", a "Bridge" and a fake plant that I'd like to put in the hosp tank.  I figured since the Lionfish and the Eel like to hide

FOWLR mates for lion  - 02/16/2006
Guys I'm setting up my new tank (150 reef) and want to keep my 55 as a FOWLR. Wanted to get a lion with a couple mates. I made a nice cave for him. Always wanted one. I've read the compatibility charts and Mr. Fenner's book says most mates become aqua popcorn. I was thinking something that wouldn't harass like a butterfly trio (Black &White/Dot Dash/Pakistani,) all "good butterflies.
<Good choices>
I really want to focus on 1-3 mates that won't hassle him. I also want to be the only one in the house that enjoys $50 dinners not my fish.  What inverts can I have? Are hermits even popcorn? Thanks Jeff
<Sessile (bottom, slow to non-moving) types... like echinoderms (hardy ones... covered on WWM), larger hermits (small may be inhaled) will work out. I take it you've read re Lion Compatibility on WWM: http://wetwebmedia.com/lioncompfaqs.htm
Many choices... as you say though... not animals that will pick on the Lion, nor be sucked up by it. Bob Fenner>

Fish compatibility... lions, triggers, puffers  12/21/05
Hi,
<Hello there>
      I looked over puffer/lion fish FAQs are could only find that porcupine puffers (Diodon holocanthus) are not recommend with long finned lion fish because of fin nipping habits.  Does this mean that a dwarf fuzzy lion or fu Manchu lion fish have a better chance of compatibility?
<Mmm, no... not really. More to do here with the sedentary nature of Scorpaeniform fishes period. In general they're easy pickings>
especially since these particular lion fish have fins closer to body, and are more likely to stay close to bottom of tank and rock work plus are nocturnal hunters compared to the porcupine puffer which stays in middle area between surface and bottom most of the time.  Do these fish have a better rate of compatibility together if they are fed on regular schedules, and adequately enough to sustain contentedness even  though these fish are known to gorge?
one more question, what are the chances of compatibility of a Picasso triggerfish and dwarf lions?  
<About the same. Not good>
According to WWM it is not recommended because trigger will become more aggressive with time, but I just want to know the possibilities.  I trying to stock a 110 gallon fish only tank and want to know my options, I know filtration is an issue with these larger fish, but I am prepared.  
<Chances... I'd say about 50:50, diminishing with age, time, size. Bob Fenner>
thank you for your time and help! Much appreciated!

What I Want and What I Get - Lionfish with Tang and Trigger 11/30/05
Hi!
<<Hi!>>
I would like to get a lionfish for my aquarium, would it be able to live with a tang and triggerfish?
<<Without knowing ANYTHING else about your setup, I can tell you that the trigger will be a problem with lionfishes.
 They are known to bite off the ends of their spines (ostensibly to eat the now de-venomed fish). Please, also, go to our homepage, enter your search terms (lionfish compatible trigger tang), then when you get the results hit the 'cached' link to see your results with the search terms highlighted. In short, I would not recommend it without knowing MUCH more, and even then may not. Marina>>  

Lionfish tankmates 11/16/05
Hi I have a large lionfish that in the past has caused a stingray to die from a wound. The clumsy stingray bumped into the lion and died a few days later. Anyway, I have a valuable tesselata eel in one of my other tanks and would like to move it to the lion tank. I always see people keeping lions with other predatory fish but I just wanted to make sure that the same thing would not happen to the tesselata. Do most fish instinctively know to stay away? Dinesh Patolia 
<There is always a risk, but unless you have an especially belligerent or aggressive lion, the eel should be able to stay away. Your stingray was at much greater risk because it is a much larger target and can't maneuver very well. Best Regards. AdamC.>

Lions tryin', Lion Compatibility  10/19/05
MacL- (Or, any of you kind folks at WWM.... but Mac knows my story well.... )
<Mmm, just saw this...MacL not checking her in-box?>
Mac- Sorry I have not been updating you on the lions. My two attempts
at adding another lion fish to the tank failed, and I have not tried it
again. It has been a pretty lonely tank for Big Daddy for the last
several months. I tend to get very discouraged when the animals pass
on, and I do not want to keep on risking it. Moreover, I really do not
want to expose Big Daddy to any stress from having not-so-healthy new
tankmates, so I try and not add anything. I had lost the man who was
taking care of my tank because his business went under, and it has been
a real loss. He used to personally order the fish from his suppliers and
quarantine and treat them for several weeks before adding them to my
tank. I have NEVER had such luck with purchasing stock from a LFS. Kind of disappointing.
I did however, take on one tank mate for Big Daddy. Unfortunately, it
is a maroon clown, something I swore never to have after my previous
clowns turned out to be S.O.B.'s. But, my friend had to take down his
system and had no where to put his last remaining fish, so I agreed to
take him. He is large and really beautiful. He has acclimated to my
system wonderfully, and so far, hasn't been an ass.
In any event, I also knew that I would be having a move coming up, and
I did not want to add anything to the tank before this move.
SO... here comes the problem.... I had the move, about 8 weeks ago. The
tank held up wonderfully, and I really think was looking so much better
after the move. After about 5 weeks, I felt it was safe to try and add
a few things. I added two yellow tangs because I have a (sometimes too)
healthy growth of Caulerpa. The tangs were a great addition. The clown
got an anemone in the process and has kept himself busy with that. He
doesn't bother the tangs, I suppose, because they are such a
drastically different body type. Big Daddy seems to enjoy the company
as his coloring is better and he seems to be more active and not hiding
in the back.
So we live in Houston and were (ever so) slightly affected by the
Hurricane in the sense that we have had rolling blackouts for several
days. Thankfully, our house and property where saved and we only had 60
mile an hour winds here, but as I said, we lost power many times with
the last being two days ago. I had an aerator that was powered via a
car battery on standby, but the power was never really off for longer
than 2-3 hours. I never used it. I THOUGHT that 2-3 hours would not be
detrimental, but could it have been being that it probably happened 8
times over a week?
<Sounds like all was/is okay>
I had to go to Canada for work over the weekend and my mother was
taking care of the tank. She is very educated on SW fish and what not.
She had to go out of town herself on Sunday, so no one saw it Sunday or
Monday until now. Big Daddy looks bad....
The tank had run out of water in the sump enough to get air bubbles
flowing pretty heavily in the main aquarium. I have no idea how long it
had been doing this, but let's assume over 24 hours. Big Daddy was
huddled in the bottom corner covered in air bubbles. I immediately
added water to the tank, and everyone else in the system looks fine.
All the corals are doing well, too. Big daddy, however, is still very
pale and has white spots again. His eyes have slightly fogged and I
notice several white spots on them, a s well. Sadly, his tail fin has a
slit in the middle of it but is still connected at beginning and end,
looking like a skinny donut hole.
In all these comments, can you notice anything that would be the direct
cause of this, or could he just be stressed out?
<Likely just the latter>
No one else in the
tank has any symptoms, though... I have run out of supplies and will
head to the store tomorrow if possible with work so that I can do a
water change tomorrow night, but it might not be until Wed. morning
that I can do this.
I tried to feed him, but he was not hungry. My mother said the last
time he ate was Thursday. He usually eats every 2 days when he is
feeling normal. I will try and feed him again tomorrow.
Since writing this e-mail, he has begun moving around the tank more,
and looks to be acting normal at least, but he does not look good.
Hopefully, since he has proven so strong before, he can push through
this as well.
Is there anything else I should be doing to try and help him along?
<Mmm, not that "pops out" in my mind>
I will do the water change. I will try and get him to eat. Do you have
any feelings on Kick-Ich? I have used it before, but I never really thought it worked....
<Is a farce... please Google WWM re>
If he is worse in the morning, I will send a picture....
I apologize for such a novel-length e-mail, but I like to include all
the recent history to see if something sticks out to you as a problem.....
Thanks for your time!
Brett

Triggerfish and Lionfish Compatibility 09/19/05
Hello!
<<Hello Ben, Ted here>>
I have a 125gal aquarium. I love lions and i will definitely be getting a Volitans lion. Here's my question, I would love to try a trigger fish, is there a triggerfish that could live with a lion? I was thinking about getting a Picasso (sp?) <<Picasso>> triggerfish. <<I would not recommend putting a Picasso triggerfish in with a lionfish. Please see these search results from WWM (http://www.wetwebmedia.com/lioncompfaqs.htm). After looking at these FAQs, please do other searches on WWM such as "Lionfish and Triggerfish".>> Here's my line up for my 125gal:
-Volitans lionfish
-Goldentail moray
-Picasso triggerfish
-Lunare wrasse
Thanks,
Ben
<<You're welcome and good luck - Ted>>

Dyin' For A Lion! (Lionfish Suitability) 6/31/05
Hi Crew,
<Scott F. your guy tonight!>
You guys do great, hard work and it's appreciated by all who can read.
<Glad you enjoy it! We're proud to bring the site to you each and every day!>
I've been reading your site for the past week, which means I've
probably read about 1% of the total information and all of my
questions have already been answered in the remaining 99%, so I'll
understand if you point me back to http://www.wetwebmedia.com.
I have a 20 gallon FO marine tank cycling with two Damsels.  I realize now, thanks to you guys, that this is unnecessary and that live rock is a better situation, but the fish are strong and eating voraciously (I'm also feeding them once a day an amount they eat in about a minute to keep waste down).  It's been running for two weeks, I finally got my test kit and for the last three days the results have been:
Ammonia - .25
Nitrite      - .1
Nitrate     - 20
In this size tank the water changes faster, how often to you recommend testing?
<I'd try three times weekly during cycling; twice weekly thereafter.>
I've been to seven LFSs in Phoenix and they've been either lame or
overpriced, any recommendations for either LFSs or a reputable online retailer?
<Unfortunately, I am not familiar wit any stores in the Phoenix area, but you might want to contact a local aquarium club, or consider posting in the WWM Chat Forum to see if any local hobbyists can refer you to a good shop near you!>
Besides the bio balls in my tank I'm using carbon 24/7, is this
acceptable in a FO tank?  (This is the one where you might direct me to http://www.wetwebmedia.com)
<I would recommend further reading. However, I am a big fan of continuous use of activated carbon. Along with regular water changes, careful feeding, and aggressive protein skimming, carbon is a great ally in maintaining high water quality.>
My dream is to get a lion fish, either a Dwarf Zebra or Fuzzy.  I know this is pushing it for my size tank, but I'll be getting a 60g in 7 months.  If I get a 1" to 1 1/2" lion fish how long do I have until he grows up to be too big?
<Not too long, really. This tank is potentially too small simply because of the amount of metabolic waste even a small Lionfish can give off. They are heavy feeders. Better to start the fish in the 60 gal, IMO>
Thank you guys.  I also had one idea that would help people like me. How about a section that lists certain types of compatible fish? It could be listed by the main fish that people want, like Lionfish and then you list three of the most compatible fish.  It would be a lot of work, but I would find it very useful.
Thanks again, JP
<That's a neat idea, JP! Unfortunately, it's hard to be 100% certain about ANY fish being compatible. I have seen some charts like this in various online magazines, like "Reef Keeping". Also, Scott Michael, in his books, does a great job at discussing compatibility of various fishes. Check out these and other resources on the Web. Good luck! Regards, Scott F.>

Moray stung by a Lionfish...
Hello. I purchased a 2 foot Chainlink Moray Eel and he was very healthy when I introduced him into the tank. A few days ago my Lionfish stung him twice.
<Yikes... not compatible...>
He has survived and is doing ok considering what happened. He had open wounds so I dosed him with medication.
<... ?... for?>
He seems to be doing better but now he is losing the skin on his underbelly where he was stung. Any suggestions? Thanks so much for your time.
<Keep the system optimized and stable... and the fish well-fed... Bob Fenner> 

Lion Fish, Not Lyin' Fish..
Hello, and thank you for providing this service to us all, definitely well appreciated! 
<You're welcome> 
I am just starting in this hobby and have absolutely fell in love with lionfish. My issue is my girlfriend likes the pretty, colorful additions to the tank. ( Dottyback, blue velvet damsel, small yellow tang, purple Pseudochromis, and my buddy, a 8" snowflake eel, then there's the clean up crew: turbo snails, emerald crab, blue hermits, peppermint shrimp,
pencil urchin, brittle star. And the others: Condy anemone 2", misc. small frags of pieces of coral) The equipment is as follows: 50Gal wide 30"x18" Oceanic tank, Fluval 304 canister filter, 2" of live sand, slowly adding live rock piece by piece, up to about 25 pounds now. I have been trying to do my homework on this but am finding conflicting information. I am very carefully considering buying a Pterois antennata. The information I have found says that they get to be about 7-8 inches and that they eat shrimp and crabs I can live with this. With the smaller size of this lionfish breed, if that info is accurate, please let me know. Would my other members of the tank live in fear of being eaten? Would the lion actually eat them or is the information of eating shrimp and crabs accurate? 
<Robert, your tank is overstocked right now. Adding a lionfish will create waste problems leading to nuisance algae. The yellow tang really needs a minimum of 75 gallons. It is small now, but will grow. This goes for the eel also. FYI, do a Google search on the Wet Web, type in keyword "lionfish". Here you will find info you need on this fish. James (Salty Dog)>

Not Lyin' About the Lionfish
OK so I'm already over stocked, I already have plans to add a protein skimmer (could you recommend one than is not HOT or in sump, a canister type one that will allow me to keep the top of the tank sealed for the eel?)...
<I know of no canister type protein skimmers.> 
... will make the adjustments to the tank conditions, that really wasn't my question. Although any advice from a voice of experience is appreciated. Will this breed particularly, eat the others in the tank?
<A lionfish will eat anything it can get in its mouth. I have seen them eat good size goldfish although that is not the recommended menu.> 
The yellow tang is all but bought, if you ask the girlfriend she already has one in mind, (kinda like me and my lionfish), but I can talk her out of it. Will the lion torment and eat the other fish or will it be content to eat the shrimp, crab meat, and other goodies I provide?
<There is much you don't know about lionfish. From the factory, so to speak, they won't touch anything that isn't alive. It takes time and patience to acclimate one to eat frozen type foods etc.> 
I have scoured your pages, as well as most any other page I can find, for info on the spotted lionfish and have come up with very varying responses. It'll eat crustaceans, it'll eat anything, they get 1.5' long they get 7" long, about the only thing they can all agree on it the spots on the fins at maturity and the lack of a membrane to the ends of the fins. Thanks again. 
<Obviously you are going to get the lion one way or another, that's your choosing. The eel alone will grow quite fast and if you have no plans for a larger tank, you will encounter all sorts of problems. Good luck. James (Salty Dog)> 

Lionfish compatibility 3/11/05
Hello, I would like to know if a Fuzzy Dwarf Lionfish would eat a Firefish.
<almost certainly>
If he would could you tell me what small fish that the lionfish would not eat?
<generally those that it cannot swallow whole. Be safe and only keep tankmates as long as the lionfish>
Thank you very much. Please write back soon. Jason
<best regards, Anthony> 

Dwarf Fuzzy Lionfish Compatibility
Hi, I'm Nick and I'm twelve and my dad and I have a 55 gallon salt water tank and we were thinking of adding a dwarf fuzzy lionfish. We currently have a tomato clown w/a rose anemone, a yellow tang, a scooter blenny, a lawnmower blenny (approx. 5" long), 7 or so turbo snails, 2 black neon gobies, 2 firefish gobies, a feather duster, an arc-eyed hawkfish, a Dottyback, a red flame scallop, 5 tiny blue leg hermit crabs, green hair algae, and about 20 lbs. of live rock, all happy and doing fine. We're planning to add another 35 lbs. of live rock before we get the lionfish. Is this a good setup to get the lion? We have many hiding places for the fish, so they won't (hopefully!) get eaten.
<You say that everything is happy and doing fine. Adding a lion to the mix would almost surely change that. They are not community fishes, and will consume smaller fishes as well as invertebrates that will fit in their gape. To compound things, Lions have specialized feeding habits. All in all, I would not recommend your purchasing a Dwarf Fuzzy Lionfish for inclusion in your marine reef aquarium, Mike G.> 

Lionfish Sting
Hi Everyone!
Thanks for taking the time to help me out.  I have a 65 gal salt tank with a yellow bar angelfish (juvenile), a maroon clown, a fuzzy dwarf lionfish, and a yellow longnosed butterfly fish. Everything was fine until yesterday morning when I noticed that the butterfly was acting funny, he seemed to just be swimming around with the current of the tank. My husband noticed two wounds on his underside like he was poked. We are guessing that he ran into the lionfish. My lionfish is very active and friendly. Since yesterday the lion has been sitting on some live rock on the back of the tank not moving. This is very strange behavior. So I jumped on your site and tried to research lion stings to other fish. What I got out of it is that usually the fish will die within 30 minutes of the sting... if they live past that, there is a chance they will pull through. This morning the butterfly was wedged between some live rock, my husband let him free and now he is on his side on the bottom of the tank. He is still alive and moves around a little. I don't know how to help him, I am thinking I should just leave him alone. He has lived over a day now. He has not gotten worse but hasn't gotten better either. What would you do? 
<Heidi, it is possible that this could happen but unlikely. Has the butterfly been eating good, and what foods do you feed it? Does the angel show aggressive signs? Angels do have a very sharp spike just below their gill plate which is also used as defense. It's also possible that the angel could have done this. James (Salty Dog)>

Dwarf Lionfish Companions?
Hello all.
<Hi there! Scott F. here tonight!>
I'd like to start by saying you run a great site.
<Thank you for the kind words! We're thrilled to be here for you!>
I've been doing a lot of research on keeping dwarf lionfish, and have decided to keep a Dwarf Zebra Lionfish (Dendrochirus zebra) in a 29 gallon aquarium. I will use a 20 gallon sump with the aquarium. I was wondering...will a larger species of Damselfish (I am looking specifically at the Blue-Banded Sergeant Major, Abudefduf oxyodon) do all-right with my Lionfish in this tank? I understand I will be unable to keep small damsels, as they will be eaten, and that some larger species have aggressive tendencies. Will this damsel pester my lion to no end?
<Well, to be quite honest, I'd be very hesitant to recommend keeping this damsel with the Lion. Almost all Abudefduf Damselfish are rather nasty, and there is a very real possibility that the damsel can harass the Lionfish excessively.>
If this is not a good choice, what other tank mate might do okay with my Lion?
<I'd consider a Halichoeres species wrasse, which should be able to hold its own and not harass the Lionfish. Other, small laterally-compressed fishes will work, too. Do a little research on the WWM site for some possible candidates!>
Thank you so much for the help. Keep up the good work-you help more people than you can imagine.
Go with God.  Jeff <><
<Glad to be of service, Jeff! Regards, Scott F.>

Dwarf Lion and the "oopsie" factor.
Dear Sirs,  
I bought a 3" dwarf lionfish.  Will it eat a 3" royal Gramma, 3'
sailfin tang, 4' red Coris and 3" clowns?  People at fish store said no,
it'll grow up with them and everything will be fine.  I ran into your
website and I'm saying to myself oopsies.  
Sincerely, Renee
>>>Hello Renee,
Yes, no, no, and yes. The royal Gramma and clowns don't have all that much more growing to do.
Oopsie sounds about right. :) You need consider how "tall" the fish is, which makes a big difference. A 3" royal Gramma is much easier to swallow than a 3" tang. Keep in mind the eventual size of the lion vs. these other fish as well. Stick with larger fish, as even the smaller lion species attain a decent size - certainly large enough to ingest some of those fish you mentioned.
Cheers
Jim<<<

Dwarf Lionfish, compatibility, aquarist danger
Hi <Hello Karen>
I tried to search your site for the answer but could not find either.  Hope you do not mind I have 2 questions.<No problem>
1.  Would a dwarf lionfish be compatible with a Banggai cardinal & coral beauty.<The Banggai cardinal might be a snack for the lion depending on it's size.>  I also have chocolate chip starfish, orange star, black sea urchin.  Various snails and hermit crabs.  Torch coral, green star polyps, cabbage leather, button polyps
and a few candy canes.
2.  My hands are in my tank a lot.  I am very worried about them being venomous, would I be protected if I were to wear latex gloves  say up to the elbow when in the tank?<The sting is not lethal unless you also have a strong reaction to bee stings, none the less do avoid the dorsal fin. James (Salty Dog)>
Thanks

Fuzzy Dwarf Lionfish
Hello! Great website, very insightful!, Well here is my question. I have a
46 bow front (this is not my first tank), with 50# LR with plenty of caves
and such, testing 0's on nitrates, nitrites and ammonia, 8.2 PH and 1.023
salinity. I have a brain coral, doing well, some polyps and a mushroom rock
all healthy. The only fish in the tank are a leftover yellow tail damsel
(doing fine) and a 3" Flame Angel. I added a Fuzzy Dwarf (approx. 3"), (my
favorite fish) anyway last night all was well. This morning the Flame was
dead. It had a large white swollen spot on the side of its head.
It seems
the Lion and the Flame had a disagreement and the Lion won. Does that sound
like a lion sting?
<Maybe... but the angel loss could just as well as be unrelated>
The Flame was healthy and eating well.
Any info would be appreciated. Also what would you suggest as another tank
mate for the lion?
Rob
<Something bigger than its mouth, but not too likely to pick on it. Bob Fenner>

- Dwarf Lionfish -
Hi there,
Firstly I would like to say how great your website is, it's very helpful. I have a quick question for you. I have just bought a dwarf lionfish and I was wondering if it will eat any of my other fish? I have a pair of clowns, a goby, a psychedelic mandarin, a yellow tang, a small damsel and 4 green Chromis. I also have turbo snails, hermit crabs a cleaner shrimp and a pink lobster. Will any of these eventually become expensive fish food? <It's possible, yes... although most likely with the smaller fish.> Also my lionfish doesn't seem to be eating, the shop where I got him said that they do take about a week to start eating because they don't like to be disturbed but it's now been in the tank for over two weeks. What do you recommend feeding him, I have tried frozen and live brine shrimp, ghost shrimp and a small guppy. <Suggest any seafood item - shrimp, krill, scallops, clams, white fish, but not live feeders. Put the selection on a feeding stick and dangle close to the fish. I'd also try this just after lights-out... these fish prefer darker spaces and would do well if you could provide it a cave or similar structure to call its home.>
Thank you for your time and keep up the good work
Allie
<Cheers, J -- >

Lionfish tank mates
I haven't had a chance to thank you for the advice.  I went with this:  1 fuzzy, 2 percula clowns, 1 pink watchman goby and a black leopard wrasse.  There are also 2 starfish a corral banded clown (thought it would be a snack but, it's been in there since May).  I haven't been able to find a corral beauty locally.  I am thinking of adding either a porcelain crab or green emerald. << Coral Beauties are very popular, you shouldn't have to look far for one.  Porcelain and emerald crabs should be fine.  Emerald are probably a better choice in this situation. >>

Compatibility
Hi, <Hi Alex, MacL here with you today.> I was wondering if I could house a Zebra Moray and Dwarf Fuzzy Lionfish together in a 100 gal comfortably for their whole lives? <I know people who have done it, but their tank was larger than yours. I would think the secret would be to keep the Moray fed.> Thank you!

Hi,
Do fuzzy dwarf lions and Volitans lions get along good?

>>>Sure, just make sure the fuzzy lion has some size to begin with. You don't want him getting swallowed by the Volitans - they grow FAST.

Tank Compatibility Questions
I have a 6 inch clown trigger, a 7 inch Picasso trigger, a porcupine puffer,
green wrasse, miniatus grouper and 12 other fish in a 350 gallon tank.
<The other twelve we'll assume all are compatible, similar in temperament>
I love puffer and would like to add a 6 inch stars and stripes and I love
lions and was going to add a 6 inch Volitans lion.  I also would like to add
a second fox face lo. The first lion (antennata) lasted 12 hours.  
Any chance that the lion can hold it's own?  How about the second fox face
or second puffer??
<The puffer would likely be fine... as long as you can get it (I'd train it while in quarantine) to accept food from a "feeding stick" (to assure it's getting fed), and the Lo/Siganus should also be able to be added... but Lionfishes in with triggers are a bad match... too likely to get eaten by them if not starved by competition. I would get/use another system for your Lions. Bob Fenner>
Thanks,
Cara

Cloudy eyed lionfish
I have recently noticed that my lionfish has some cloudiness in its eyes and has been occasionally sitting on the ground.  My main concern is the cloudiness...but when he sits on the ground he will have his fins down, that is until the Picasso trigger swims anywhere near him.  I have looked through other FAQ's but haven't seen anything that answers this question.  Do you have any suggestions or recommendations?
<The root cause of this condition is almost invariably water quality related... do check your pH, alkalinity, and in any case, do a good-sized water change (like 25%)... And look into either getting another system, or trading one of these animals... triggers and lions are not compatible in most all settings. Bob Fenner>

Ongoing Lionfishes trial ends
Mac- <Hi Brett, so sorry to hear your sad news. : {>
Unfortunately....Baby Daddy passed on this morning. :( I suppose I will have to be a little bit more selective when I get ready to add Baby Daddy 2 to the tank. <Well I think you were trying to be selective and I can't imagine a greater tank than to be with someone like you that truly cares.>
Is an antennata an appropriate choice for a tank mate for my Volitans? I definitely wanted a different species...and I think antennata are some of the most beautiful... <I do as well and I have seen them work successfully. I can't know what your guy died from but honestly I don't think he was right from day one. >
As you can see from the pictures I sent you, after several days, Big Daddy was fine with Baby Daddy. <I think Big Daddy is GORGEOUS.> I think if I started with a lion that was slightly larger than the original antennata, I will have much better luck. <I think you'd feel more comfortable.> The LFS TOLD me that he was already eating frozen freeze dried food, but I suppose next time I will ask to see a feeding the day before I bring him home to make sure they are eating. <VERY SMART!!! Its not that they try to mislead you, just that to them one bite might be eating where you'd like to see a fish that eats like a pig.> Since I don't have the ability to quarantine, I think I really have to get a lion that at least is familiar with frozen foods. <Definitely get one that is eating heartily because you just don't know how long he has gone without foods.>
Any suggestions on what I should be looking for in a new tank mate for Big Daddy would be helpful.... I am going to start the search in a week or so.
Thanks for all of your help. Baby Daddy's passing was not due to a lack
of care or concern, and I appreciate all of your help. <I wish I could have been of more help.  Just look for one that is eating well and that "looks healthy".  I know that seems vague but if he's washed out looking at all that doesn't bode well.>

Creating a Compatible Community (Stocking Question)
'Sup WWM crew!
<Hey! Scott F. with ya' today!>
I'm just coming back from deployment and I want to set up a 40 gallon aquarium. I'd really like to get a Fu Manchu lionfish, but I would like to have at least one other fish in the aquarium if possible. So far I've considered a Valentini puffer, a small Snowflake Eel, or a Centropyge angel (Coral Beauty or Pygmy maybe).
<I would not even think about the Puffer or the Eel in this sized tank, so the Centropyge looks pretty good!>
I have a BakPak IIR from my last aquarium, and I'd be buying a good
hang-on filter. I know it would be a bit crowded, but I'd be picking up smaller sized fish, since I plan on buying a much larger (150 gal or more) aquarium in the next 6 months.
<I'd avoid assembling this mix of fishes until a larger tank is up and running. Even then, mixing a Puffer and the Lion could be a potential problem.>
Anyway, I was wondering what you folks think about this setup... Does it sound good? Or are there any other tankmates that would work? Or am I crazy!!!
Thanks, Jarin
<You're certainly not crazy, Jarin! But I would consider smaller tankmates in this sized setup. Or, better yet- why not just keep the Lionfish on his own for a while, then move him into your larger tank, followed by the other proposed tankmates. This will help this shy fish become more comfortable...The best way to go, IMO! Good luck! Regards, Scott F.>

Dwarf Lionfish Questions
Right now I have Volitans lionfish in my 150 gallon tank...any problem if its a male Volitans and a male dwarf? <Not usually. The dwarf Fuzzy lionfish (Dendrochirus brachypterus) is the only one that I'm aware of in which two males will consistently fight, with sex often being difficult to determine in the P. Volitans.>
Also Let me know what you recommend for a dwarf. A short fin? A Fu Man chu? etc.....tell me which one you find the best for home aquaria. <In my experience, the Fuzzy Dwarf listed above is both the easiest to maintain and the hardiest, with the Fu Manchu often being among the hardest to convert over to non-living foods as well as being completely intolerant of others of its own kind. The P. russellii is, in my opinion, the easiest of all the lions to keep and somewhat smaller than the P. Volitans at about 12" when mature yet still mixing well with its larger and smaller relatives.  You may want to consider one or two of the more traditional medium scorpionfish as well, as they are also compatible, often quite colorful and remaining on the bottom, thus not competing for the same tank areas.....I have a False Stonefish (S. diabola), a New Guinea Scorpion (S. papuanensis) and a Barbfish (S. brasiliensis) all housed with lions and doing famously.  It never ceases to amaze me that some of these decidedly predatory species are among the least territorial in the hobby with some actually appearing to form actual "friendships", seeking each other out for company. For added variety, the morays of the genus Echidna and Zebra morays also frequently fit in with no disputes of any kind.  A Lionfish/Moray tank ALWAYS gets amazement and attention, yet is surprisingly easy.>

Lionfish Tankmates
Hi Bob;
<Hi...you've MikeD here>
I have a 40 gallon tank with about 30 lbs of live rock and a 2 inch dwarf lionfish.  What would make good tankmates? What species of fish?<Species that are slower moving and not territorial usually works best, such as a marine Betta, a smaller scorpionfish, waspfish or a Hamlet. Small species will be considered food, so something in the 3"-5" range is your best choice.>. What species of inverts?<Almost any invertebrate will be fine except small shrimp (including cleaners) and crabs, which are the foods of choice. Dwarf lobsters, sea stars, sea urchins, sea cucumbers, etc. all work well.>  Unfortunately, I will not be able to upgrade to a larger tank for at least two more years so this is a limiting factor.  Also, I am having problems with green and brown algae in the tank.  The snails that I have fall off the rock into the sand and die when they cannot right themselves (and I am not there to put them back on the rock).<This is quite common, with Astrea snails being less prone to this .>  Should I buy more snails (what species), or add to the roughly 15 dwarf and scarlet hermit crabs that currently inhabit the tank?  Or are there other algae controllers that could live in my small tank and coexist with my lion?<Algae control in a marine tank is often problematic as there are relatively few herbivorous crustaceans. Larger emerald crabs that are too large to be eaten might help somewhat, with shorter periods with the light on often helping as well.>  Thank you.

Aggressive Fish Tank Questions
Hi,
<Hi, MikeD here>
When my 200 gallon tank gets fixed I am planning on starting an aggressive fish tank.<That's a good sized tank for your plan.>
I have a wet dry filter and a skimmer and a large Rio powerhead.
Here's what I plan on having
Volitans Lionfish
Harlequin Tusk
Clown Trigger
Niger Trigger
Koran Angel
Puffer (maybe)
Would this be too crowded? <Initially, no, but as the fish grow, yes.>
Are these fish all compatible?<In my opinion, no. I usually strongly suggest only Crosshatch, Bluechin or Sargassum triggerfish in tanks to contain Lionfish or other slow ambush predators.>
Should I get a Puffer instead of the Clown Trigger? <I would strongly recommend this course of action. While small clown Triggers are often quite delicate, once they begin to grow and mature most end up killing EVERYTHING in the tank with them eventually. The brilliant and beautiful coloration of a Clown Triggerfish is an excellent example of "warning coloration" advising other creatures to beware.  While the Niger Trigger is often far less aggressive, they too can change overnight and can grow to 19" and the poison fins of a lionfish are no defense at all against an irate trigger.>
Also what order should I get them in?<With the other fish that you've listed, order is relatively unimportant except for the Angel, which should be added last if it has any size to it. This has an added advantage in that many Angels do poorly in newly set up tanks, with one year often being the magic number, at least in my own experience.>
Any other info you could give me would be appreciated.<My only other suggestions would be to utilize natural foods cut to appropriate size for all but the Angel, as this will cut down on oils and particles that often lead to cloudiness and bacterial blooms.  While may "formulas" and cubes appear logical, they often create more problems than they solve.>
Thanks,
Adam Siders

Lionfish Compatibility
<Hi, MikeD here>
I have a five foot long, one hundred gallon, fish-only tank.  It is home to a six inch Volitans Lion and an eight inch Snowflake Eel.  These two have gotten  along fine except occasionally at feeding time when all hell has broken loose.<Using a feeding stick or a long pair of tongs will prevent this if you "target feed" the eel in the LR.>
  I recently added a three and a half inch Red Sea Angel which has adapted to my aquarium very well.  My only concern is that the Lionfish has made several unsuccessful attempts to make the Angel lunch.<I strongly suspect that he's merely attempting to drive it away from him, rather than making it "lunch".>  Just prior to adding the Angel I fed the Lion an ample amount indicated by his bloated stomach, yet once the Angel was in he went right after him.  Now I understand the Lion has a rather large mouth but after much discussion with my local fish guy we both concluded that the tall body would likely prevent the Angel from becoming an
expensive snack.  Now either we are mistaken or the Lion is just not too fond of his new roommate and imposing his dominance.  Any thoughts on this matter would be greatly appreciated.<I suspect that you are correct in your assumptions, although territoriality is likely not the primary reason Many juvenile angels have body shapes similar to damselfish, notorious fin-nippers that are high on the Lion's list of fish to be kept at a distance.  In addition, some angels serve as cleaners while young, which would tend to re-enforce the lionfish's keeping it at fin's length out of self preservation.>

Chocolate Chips and Lionfishes
Hi all!!!
<Hi, MikeD here>
I believe, sadly, that my Chocolate Chip Starfish is dying. He seems to be melting away (one limb gone and seems to be spreading). The arm was white 2 days ago, I found him "stuck" to my powerhead and removed him.<It's being stuck is due to it's weakened condition as a normal chocolate chip starfish has plenty of strength to walk away, even one that was injured.> I checked your great site and learned that the white might possibly be caused by stress. He also looked quite shriveled that day, but became very active once removed from the powerhead...I assumed that stress was the cause.<Stress may have been a contributing factor, but it sounds like your animal may be the victim of an active infection that I've seen before in sea stars.  While it's unknown as to whether it's a bacterial or viral infection, it seems to be almost universally fatal and highly contagious to other sea stars as well. The one consolation is that it seems to affect the sea stars only, having no effect upon sea urchins, sea cucumbers or any of the other echinoderms.>
The next day, I saw that my fuzzy dwarf lionfish was "aggressively" checking him out.<Any interest by the lionfish was purely in looking to see if there were any small sea creatures actively attacking the infection site, such as small shrimp or isopods which would have been greedily gobbled up.> Are they able to peacefully cohabitate as I was told that they were? <Without question, yes they are.>
Alas, my poor Chocolate Chip now looks as if he were dipped in milk, will he eventually die or is there something I can do? He is still active and eating...Please help!!<This is one of those situations where I truly believe that there is nothing that you can do, with the exception of removing the animal in hopes of preventing the spread to other sea stars that you might have.  If you have none, I strongly suggest that you wait a month or two before introducing another, one of the things that makes me suspect a bacteria, virus or even parasitic protozoa that needs sea stars to survive and dies off without their presence..... I've never had a spontaneous reoccurrence of the "disease" once it's run its course and killed all the sea stars in an aquarium. In all instances where I've had this occur, it was shortly after the introduction of a new sea star....it may be possible to bring it in with an introduction of another animal, such as a fish or coral that was kept in an open system at the LFS that contained sea stars, a reason why even invertebrates should be kept in isolation as a preventive measure, but this is pure speculation as, again, any instances I've seen were with the purchase of an infected animal.>

- Lionfish & Cleaner Shrimp and Other Questions -
Hi guys,
I'm wondering will a lionfish eat a cleaner shrimp or a cleaner wrasse? <Think it might leave the cleaner shrimp alone, but hard to predict. Would need to keep it well fed. As for the cleaner wrasse, I don't really endorse their use in captivity... these fish should be left in the ocean.>
Also could a Asfur and a annularis angel live together in a 5ft x 18" x 24"? <They could for a short while, but really not a tank large enough for these angels even individually.>
Thanks.
<Cheers, J -- >

Lionfish Compatibility
Dear sir,
<Hi, MikeD here>
Don't mean to intrude, but I found you to be a knowledgeable person
regarding sea-aquariums, so... Perhaps you can indeed give me some good
advice...<We'll sure try>
In the near future, I'm planning on installing a decent size marine
aquarium, in the area of 625-700 liters (about 150-180 gallons, I
think)<This is a beautiful sized tank>. Probably, I'll try to install it as a indo-pacific imitation  
habitat (any advice on that?)<I'm not sure what you're referring to. Perhaps the single most important question is whether you wish to concentrate primarily on fish or corals, which quite a large difference. If you're speaking of residents, that's often fine, but not a requirement, with many fish from the same region living in different mini-ecosystems so they never encounter each other in the wild>
I'd like to include a (dwarf) lionfish species, but my daughter also
really want me to introduce a 'Nemo' clown-fish. Would this work?<With the dwarf lionfish, particularly, often quite well.> I
first though of the volitans species, but since they grow way to large,
they certainly will take the clowns for food, I think<You think correctly!**grin** Large lions require particular fiends, although some mixes, such as Lionfish/Triggerfish are very commonly fatal>... Will the
smaller dwarfs try the same?<Not unless starving. The vast majority of the diet of wild dwarf lionfish is comprised of small shrimp and crabs, very easily duplicated in a home tank.>
tnx for your opinion ;)
(and I'll be reading up your site, in the meanwhile ;)) <Thank you and enjoy>

Dendrochirus biocellatus (Fu Man Chu Lion)
Hi Bob
<MikeD here instead...can you deal with the disappointment?>
I hope you don't mind me emailing you direct. I am looking for further information on the Fu Man Chu Lion fish.<OK> I am setting up a 48" x 24" x 24" reef aquarium, used to keep a lionfish about 15-years ago. Seen a Fu Man Chu in a local marine shop, and quite fell in love with it.<They ARE sweet!>
So to get to the point, I would love to keep it in a reef system, could you suggest suitable companions for a reef tank in terms of fish.<Sure...anything that won't fit into its mouth> Also would he consume hermit crabs<No, the shells are too hard to swallow>, snails<ditto> and cleaner shrimps?<With gusto, as shrimp are their main diet. This is  as close to a Scorpionfish as you'll find in the Lionfish group. Negatives are 1) they hide in the LR a lot, 2) tend to be very aggressive w/each other, and 3) often are very difficult to wean over to frozen/prepared foods. Positives are 1) they are beautiful, 2) totally non-destructive towards anything not considered food, 3)actually quite hardy as long as sufficient foods can be found, and 4) often do well in fairly small containers as they don't swim much and usually move by "crawling".  Any help at all?>
Regards
Neil

Dendrochirus Biocellatus (Fu Man Chu Lion)
Thank you for the info MikeD,
<Back again and you're very welcome>
Guess my problem is I love clownfish also, maybe I should think along the lines of two tanks, one to house the lionfish and one to house everything that will fit in its mouth.<What did I miss here? I don't see a problem with a pair of Clownfish (preferably a larger species) in a 4 foot aquarium with a Fu Manchu or even a Dwarf Fuzzy. There should be enough room to avoid territory conflicts and if you're willing to make sure that a ready supply of live ghost shrimp is on hand, it could work nicely. Keep in mind that Fu Man Chu is among the smallest of the Lionfish>
Back to the drawing board!
Regards
Neil

Russell's Lion and Tang?
Will a fully grow Russell's Lion eat a fully grown Yellow Tang?
<MikeD here. Not unless it's cut up into very small pieces. I can't visualize a P. russelli even trying if it was starving to death>

Lionfish and Porcupine Puffer In One Tank
<MIkeD here again>
Better yet, could I put a Russell's Lion and a Porcupine puffer in the 90
together and call it good?<They'd be fine for a while, but again, both get large and produce copious amounts of waste> or would the puffer snack on the Lion's fins?<I've not seen nor heard of compatibility issues between these two fish, and have kept them together in larger tanks, but suspect that in a 90, eventually you'll have water quality issues and a very good chance of the porcupine puffer eventually accidentally envenomizing itself.
They're good natured but clumsy and in my estimation it's an accident waiting to happen even if it doesn't outgrow the tank.>
Thanks again for all the help!!<Good Luck>

A couple of lion questions
Firstly thank you for a great site <You're very welcome, MikeD .. I have learned a lot from the
articles and FAQS.<anyone in the hobby is always learning, no matter how long you stick with it> I have been using WetWebMedia since setting up my
tank and I am happy to say the day for fish is finally here!
My am is zero, nitrites zero and nitrates 5ppm.
The tank is a 5x2x2  I think that is roughly 130g<149.6 actually>
Question1
I have seen a lot of tanks with a mixture of lions. Is it ok to mix
species like volitans and fu Manchu? Big size difference don't want the
little fella to end up as lunch!<Wise thinking. While many species of lionfish and Scorpionfish can be kept together, in less than a year a P. volitans would be large enough to eat it and may well try if it gets hungry enough> Would it be safer to keep to the
zebras and Radiatas as companions. I was thinking 1 volitans, 1 zebra
and 1 fu Manchu.<Even the Zebra is risky with a P. volitans unless you buy a really large specimen initially, as the volitans growth rate is so much faster than either of the other. You might try a P. russelli instead of a P. volitans, as they look very similar. The Russell's lionfish is often sold AS P. volitans, with the only difference being the tail (caudal) fin.  On a Russell's the tail will be clear with no spots, while the volitans will always have a pepper-spotted tail.  The Russell's stays smaller (average 10 inches in a home tank) and has a preference for shrimp over fish yet looks VERY similar, even as an adult.>
Question 2
I know that shrimps are out but what about other inverts like anemones
and mushrooms?<no problem here at all, with the exception of small crabs being on the menu as well as shrimp except hermits). Lionfish and Scorpionfish usually won't bother any sea stars, cucumbers, urchins, snails or corals, and I've even had some luck with large arrow crabs acting as cleaners for them.>
Thanks for any help you can offer<You're welcome, I hope this helps>

Fu Man Chu Lion
Hi WWM Team. I would like to say I love your web site and I use it a lot. I have a question about Fu Man Chu Lionfish. I have a 55g reef tank with 1 blue mandarin, yellow tang, yellow fin fairy wrasse, dwarf hawkfish, lawnmower blenny, 2 percula clowns, Chistletooth wrasse, and a coral banded shrimp. I have about 65lbs of live rock and some assorted corals. I have wanted a fu man chu lion for a long time now and I am at the point where I am adding the last fish, which I have always planned to be a fu man chu. But my question is about my beloved coral banded shrimp (Gary). Will the lion eat him? << It is possible. >> I have asked many people at many different stores and they say if I keep the lion well feed he would not show any interest in my shrimp and or the shrimp is too big for the fu man chu. << I feel the same way.  I don't think of Fu Man Chu Lions going after coral banded shrimp.  He may, but if your shrimp is big enough, I wouldn't think it to be a problem. >> And if there is anything else I should be aware of with my setup or anything else. But before I buy one I would like your opinion. << Mandarin, clowns, blenny.... not the typical tank mates for a lionfish.  Most people have small reef fish, or larger predator fish.  Interesting to see your mix. >> Please let me in on your input. Thank You Very Much. << You also mentioned keeping the lion well fed.  I just want to make sure you know that well fed doesn't mean constantly fed.  It also doesn't mean over fed.  Make sure you stay away from goldfish or guppies or things like that.  Instead use krill, Mysis, and the like. >>

Flame Angel and Lion 
Hello,<Howdy!> Would I be able to mix a Volitans lion that is currently 2-3 inches, with a dwarf flame angel? Would there be any possibility of the angel being eaten, I have heard that they are smart and know to avoid lions, but I wasn't really sure. I was not able to find anything in Bob's book about this. <I would not attempt this because although the angel is smart and fast the lion will probably get him eventually.>Thank You

Clown and lion
I have a 2 to three inch or maybe bigger tomato clown and I am getting a devil lion will the devil lion eat the tomato clown? I also have 2 damsels will a regular lion eat my tomato clown?
<Please supply more information. I'll make my reply short and sweet: The Lion will eat almost anything that can fit in its mouth. You make the call on this one. Take Care, Graham.>

Peaceful Coexistence? (Lionfish Compatibility)
Hi All,
<Hey there! Scott F. with you today!>
First of all I have to tell you that you have a great web site. It must take a lot of work to organize and keep it running efficiently.
<We have a very dedicated group of good people here who make it all happen!>
I never had a reason to contact you myself as I always found what I needed through your website until this time. Here is my problem.
I have a 400 gallon marine tank with one lionfish. Never had any problems and I have to say that we got used to each other so much that it/he panics if I don't stand next to the aquarium and talks to it/him.
<Really? And they say that dog people are a strange group...LOL>
Two days ago, I put another lionfish in the aquarium and the first lionfish didn't seem very happy with the new neighbours. I really thought they were going to be best of friends, but instead, as soon as the lionfish was in the water it went on the attack mode. Now it had retired into the darkness of some caves without eating anything.
<Well, a certain amount of hassling the newcomer is to be expected when adding another lionfish into a system where one is already well established>
Do you actually think that the lionfish got jealous and is showing some anger to me? Will he accept the fact that he cannot have a 400 gallon aquarium by himself and be okay ?
<I think that you simply need to give the established fish a bit more time to "accept" the newcomer. In time, they should find some degree of peaceful coexistence. However, if things don't settle down, or the new guy seems to be on the decline, do take action immediately> Thanks and kind regards
Richard
<Well, hopefully things will work out and these two brutes will be getting a long like a couple of beer-drinking buddies...Good luck! Regards, Scott F>

Lions, Triggers and Clowns
<Hello, Ryan Bowen with you today>
I searched your website to make sure I didn't miss an answer...<Thank You!>
I just got a medium-sized Volitans Lion and would like to put him in my 58g
tank with: 2 black and white perculas, a Chromis that has been with me
through thick and thin, and a 2inch Humu. I read that both Humu and lion
should hold their own, but my concern lies in them.
Will the lion eat the Humu if he can catch him? <Likely no, but there is always a chance> Is that normal?
Will the Humu break spines on the lion? <Yes, he will nip away at the long appendages, and the breaks in his skin will become infected in time.  Not a good combo in such small quarters.>
Should I just return the lion to the store for credit? <Or the rest of your fish.  You've done the responsible thing.  Good luck! Ryan>
Thanks for any help!

Tube anemone and lion
hi! <Howdy!> I recently got a tube anemone & was wondering if I could still get a lion, Or would the tube anemone grab & eat it ?  assuming its a small juv lion, also, is there any chance of the lion stinging the anemone?<I would say go for it, they should be fine together. Cody>

Quick questions on lions
hi!<Howdy, Cody here today!> thanks for the info on the lions. iv got a couple questions though, as I'm about to get my lion! (hopefully pretty soon :D)
I'm debating between a dwarf fuzzy or a dwarf zebra.  which one of the 2 will swim around more ? out in the open ?<Neither will be very active and would probably be out about the same amount of time.> 
iv only got a 40G tank. & wanted to know what other fish would u suggest that I could have with the lion ?   iv read up in the lionfish compatibility FAQs, but still don't know what would be best ?  it would be Great if u could name some possibilities.  (my tank kinda limits me to what I can add in with a lion)   would a Tomatoe clown or any clown of any sort be ok ? what about a hawk fish ?<The clown and hawk should be ok as long as they can't fit in the lions mouth!  For a hawk I would suggest either the long nose or the arc eye.  You might also try a dwarf puffer such as the blue spot for a tank mate.  Cody>
thanks Heaps !!

Lionfish
Hello Robert. could you please advise me if it is possible to keep a
lionfish, (dwarf, or antennata) in my existing tank. The tank is 50 gallons
with a collection of soft corals, fish are 1coral beauty 3-4inch 2regal
tangs 4 inch 1pyjama cardinal 3 inch.<I would not keep a lionfish with these
fish, especially in such a small aquarium. I would be worried that the lion would
try to "hunt" the other small inhabitants which probably would fit in its mouth>
   Do I need feeder fish before I wean it to frozen foods, any help and
hints would be greatly appreciated. <Don't purchase a lionfish for this aquarium, good luck

Lionfish Tankmates Or Entrees?
Hi again Scott
<Hey there!>
My Tank is around 70 gallons- maybe a bit more.
My initial plan was to keep a lion fish preferably volitans, but now I am thinking that I might get bored with just one fish.
<It is quite possible!>
I am now thinking of maybe going for a few smaller fishes like a few damsels or something.
<They can make for an interesting, colorful tank- kinda like a freshwater Mbuna tank...lots of action>
Can you maybe help me , I still would like to go with the Lion but I ain't sure what else I can combine with it.
<Well, if you go for one of the "dwarf" species, your choices are greater...Lots of other small to medium sized fishes, like various wrasses, dwarf angels, etc that will not harass the lion, and will not become part of his menu...Worth a look or two or three on the WWM site...>
I am aware that if I go with the Lion I ain't gonna be able to put more than +/-two more fish in my tank, right?
<Depending on size, that sounds about right...It sounds like you are still determined to go with a "full-sized" model, right? I'm still a bit hesitant to recommend other fishes to go with a full-sized lion in this sized aquarium...>
Please help me with a few good combinations, I know the choices are very wide but please give me your personal suggestions.
<Well, as indicated above, with a dwarf lion, your companion choices are much greater...You will not be as limited, IMO...Enjoy the research available on the WWM site. I like the idea of wrasses and perhaps a Centropyge angelfish with a dwarf lion...>
Thanks Again. Regards,
Ziad Limbada

Compatibility. lions and horses. is a NO NO
hi, I have a 90 gal. fwrocks only tank.
may I mixed two lion fishes with seahorses since both are slow on their swimming habits?
<number one...the lions will probably eat the seahorses. and number two...lions get very large,
your small 90 gallon aquarium will only accommodate them for a short period of time>
please explain, since they-re all I want in the tank<well I suggest you invest in two aquariums
because this mix will definitely not work>

-Lions in a reef-
Hi Bob, <Kevin here today>
Your site is great, very interesting and informative. I have a 180 gallon tank (I?#8364;™m in Australia?#8364;? not sure how many US gallons that is) with a built in filter system, 300 watt power head, heater, 15 pounds of living rock and some coral (no fish as yet)?#8364;? I really want a Volitans lionfish and I?#8364;™m sure my setup should be fine for one?#8364;?
<Keep in mind that Volitans will get large and produce a lot of waste, something that is not wanted in a reef aquarium. Make sure the tank has an adequately sized protein skimmer before adding one.>
my question as what else could I put in there? I really wanted a gold spot moray eel as well, would this be feasible?
<Well, I suppose you could, but then you'd have two large waste producing predators in the tank. These guys would do much better in a separate tank for aggressive. Good luck! -Kevin>

Dwarf Lionfish compatibility
Can you help me with this simple question?
<I'll try>
       I have been reading through a lot of information about Dwarf Lionfish,
However none of the info I have read through seems to suggest any
compatibility problems there may be with Dwarf Lions (is the compatibility the some as
the larger species?)
<Yes... basically that they will inhale fishes, sometimes crustaceans that can fit in their quite-large mouths, and reciprocally that one needs to avoid animals that may well bother/pick on them like triggers, larger puffers, big angels...>
       I have a 50 gallon all fish marine tank and I was wondering if a Dwarf
Lionfish would come to blows with the two common clown fish already in the
tank. Could you please inform me of the compatibility between the two Clowns and
the Dwarf Lion fish in a tank of this size.
<There is a possibility that the clowns might bother the lion. I give you better than even odds they'd get along though, better if the tank is sixty or more gallons. The only "sure way" is to try adding the lion and observing carefully. Bob Fenner>

Lionfish Tank!
Dear Crew:
<Hi there! Scott F. here today>
I just recently set up a 75 gallon FOWLR tank for a Volitans Lionfish.  The tank is cycled and the Lion is in his new home:)  What would be a good tankmate or two for him. Wouldn't want to see him get picked on.......TIA
Jane  
<Well Jane- you have a limited amount of choices here, really. The lionfish is quite predatory, and this behavior is magnified in a smaller tank. I'd recommend fishes that are capable of eluding the lionfish, while at the same time, not picking on it! This would seem to indicate that you should stick to fishes that swim in mid water, and have body shapes that make it tougher for the lionfish to devour! Good examples of this would be fishes like tangs, certain blennies (like the "fang" blennies, which can fend for themselves despite their smaller sizes), and even some of the medium size wrasses. Do some careful selecting, and you'll enjoy an interesting tank setup! Good luck! Regards, Scott F.>

Re: Possible tankmates for Lionfish
Thanks for the guidance in selecting a couple of tankmates:)  I don't want
anyone to be eaten or my lion to be picked on.....would a Foxface Rabbitfish
work?
<If the specimen were more than mouth size, the system large enough to support all, sure. Bob Fenner>
I know they are very hardy and I think they are in the Tang family.
I'm going to check out the fang blenny too:)
Jane

The Cowardly Lion?
Hello,
<Hi there- Scott F. with you today>
I have a 90 gal tank for about a year with a 6 inch Volitans lion, a
yellow tang, and some damsels. I had some Ich problems for awhile and I believe I have made adjustments to alleviate that problem. I added a Passer angel about 4 months ago, and he seemed to get along ok, except he would nip at the Volitans tail periodically, but it didn't seem to be a major problem. Then I added a Cuban hog, and he is, as you know, a very aggressive eater.
<Yep...By the way- you may be pushing your tank's capacity here...The Passer alone will get quite large (like 10" plus), and the behaviors of all of the fishes may become very aggressive as they get larger in the relative confines of the tank>
About 6 weeks ago the Volitans got very sick, maybe bacterial, the webbing on his side fins deteriorated, and he developed a patch on his body that turned white, and lost its color. I put him in a 10 gal hospital tank, and treated with Paragon II and Quick Cure as per my LFS. After the recommended dose I did a water change and his scales and fins have healed nicely, but he won't eat. I have tried his usual diet of frozen silversides and krill, and even added live guppies, but he wont touch any of it. He hasn't eaten in almost 5 weeks.
<Not good>
Q1: What can I do to get him to eat?
<I'd start by executing almost daily water changes (like 5% of tank capacity) to help improve water quality in the hospital tank, and to utilize activated carbon and Poly Filter to help dilute any remaining medication. I'd also try administering some vitamins, such as Vita Chem, directly to the water, in the hope that he will drink and/or absorb some through his skin, and initiate the feeding process. Don't give up on him...>
Q2: Could the passer angel and/or Cuban hog have intimidated him and stressed him into this, as my water quality is good? Gregory DePetro
<I'd say that this is certainly an excellent possibility. This kind of problem often has its roots in a stress situation...I'd consider a larger tank (like 150 gallons plus) or trading some of these fishes with a friend who has larger quarters...You may notice substantial improvement in all of you fishes...Worth considering, IMO...Good luck Regards, Scott F>

- Lionfish Compatibility -
<Greetings, JasonC here...>
Hello, Just wondering if you could help us out, Like to purchase a lion fish. Need to know if it would get along with cleaner wrasse, yellow tang and grouper (pantherfish). <Likely there would be a contest to see who would eat whom first - the panther grouper grows quite large, and either it or the lionfish would quickly eat a cleaner wrasse and eventually the tang.> O I almost forgot, would it eat coral. <No.> I am not think it would because the type of fish it is. <Your hunch is correct.> Please reply. Thanks Rob!!!
<Cheers, J -- >

Re: Lionfish Tankmates
Thanks, David, for a quick reply:)   The 75 gallon doesn't have a sump, so I will check in to the Fluval or Eheim.  I have a quarantine tank and have had great results using it with my 58 gallon reef.  The lighting on the 75 is low.... the standard normal florescent.  If I added live rock would it grow out anything for a tang or even produce coralline algae?
<Low lighting will likely promote corallines particularly in the 2 watt per gallon range...but algae would be more difficult at that level. Some tangs will eat Sawblade Caulerpa others won't but Sawblade will grow and spread in very low lighting. I used to keep it in a QT with no lighting and it grew to the point of covering the tank! IMO At 3 watts or less other types of algae would be a little iffy, but if you place the algae high in the tank you will have a good chance. This or any algae culture will need to be growing like wildfire before the tang is added otherwise the tang will destroy the culture. You might consider trying Gracilaria>
Can you please give me a few tankmate suggestions for my Lion?  My reading suggested planktonic triggers as "safe" with lions......it is so hard to get reliable info.......any suggestions will be much appreciated!
<Triggers can be safe. I've have had a combination like this that worked for years. Although the lion did eat a few of my fish; including two Dartfish and a huge lawnmower blenny! The only thing that you need to worry about is fishes the lion can eat (any smaller fish like Dartfish, Chromis, damsels etc.), and mean fishes that will harass the lion ...which is why some people don't like triggers. Otherwise, just about any fish will work. If you choose to add a smaller fish and you notice the lion taking a special interest in the fish (watching it closely)...look out!>

Compatibility
Hi there,
I read over your Scorpionfish and Waspfish FAQs and websites and had a few further questions.  I am setting up a new tank and was just wondering your impressions of compatibility with a Leaffish ( Taenionotus triacanthus) or a Waspfish ( Ablabys taenionotus) of the following (not necessarily all together in the same tank--just trying to find out for each individual species):  
Valentini Puffer ( Canthigaster valentini)
Flame Angel ( Centropyge loricula)
Fuzzy Dwarf Lionfish (
Dendrochirus brachypterus)
Long-nosed Butterflyfish ( Forcipiger flavissimus)
Long-nosed Hawkfish (Oxycirrhites typus)
Are the toxins in the Leaffish and Waspfish closer to the lionfish or the stonefish in strength (I don't mind venomous animals but I don't want anything that can kill me -- just in case)?
<As venomous as Scorpaeninae/Lions is what I've read>
Also, what is the best way to train fish for frozen or prepared foods over live foods?
<Please see here re: http://www.wetwebmedia.com/goldfshfd.htm
and the FAQs linked beyond>
Thanks for all your help, Erik Jorvig

Firefish and Lionfish... Oh, My!
<Roger... Anthony Calfo in your service while Bob is away>
Good evening Rob, to start I must tell you how impressed I am with the website, I've gotten lots of info from your site and it did stop me from getting a mandarin goby (thank goodness), and I work in a pet store so I share the info I find with customers who ask about certain species I have read up on here (salt water). Although we don't sell salt water fish but the store in town that does is always closed Sundays and so sometimes there customers ask us in desperation.
Any how, I bought a beautiful 3" lion fish, I know it's not a dwarf but it doesn't look completely like any on your web site (I'm assuming due to it being a juvenile. But I digress, I have a pair of fire fish whom I have had for at least six months and they live under some slates of marble that are just wide enough for them, originally as protection from my coral banded shrimp who I'll now trade in for a prickly leather jacket (according to my research it should be a good tank mate for my lion). Any way, I've become rather attached to my fire fish and would like to know if you think that their cautious nature will be enough or if I should exchange them so that they have a better chance of survival.
<under no circumstance could the Firefish survive in this tank... they are sure to be eaten. And with all due respect... the very nature of the question indicates your relatively new participation in the hobby. Kudos to you for taking the time to gather information first. Indeed, we must take the time to learn everyday. To the point... without deference to Bob out of posterity... I strongly suggest you buy and read The Conscientious Marine Aquarist. It is loaded with the very information you seek. Easily one of the best references on marine aquariology that you will find. And keep learning! Anthony>

Lemon gumdrops for a Lionfish
I had a citron goby a couple years back and he had a great personality. I really enjoyed his behavior - it was fun to see him "flutter" and suction cup against the glass. 
<great fish indeed... charming>
I had him for almost 2 years before he passed from what I believe to be natural causes. He ate anything offered too. Anyways, one of my LFS just got a shipment of 10-12 clown gobies (slightly under an inch). They are bright yellow and judging from your site they are of the species Gobiodon okinawae. I have a 10 gallon with only a clown that I thought might suit one very well. 
<agreed>
However, I am also interested in purchasing a couple for my 55 g. My question lies in the fact that I have a small 3" Volitans. 
<"Houston... we have a problem.">
Would the "body slime" keep them from being eaten as mentioned in your site, 
<heehee....>
or would it be wishful thinking? 
<ahhh...yes. Wishful thinking... like cologne with "pheromones" in it. Ha!>
The only other inhabitant in the tank with the lion is a gold strip maroon clown. On a separate note, what is best to feed? My first citron ate mostly flakes and brine. 
<I'm amazed that your last goby lasted even a year with any significant amount of brine in its diet. Brine is completely barren food. Hollow. Instead... feed Gammarus, mysids and Pacifica plankton>
THANKS FOR THE TIME, CHRIS
<best regards, Anthony>

Quick Picasso Trigger Question
I have a quick question. I have a small (3") Volitans Lionfish. I want to purchase a small Picasso. Will there be a problem with the Trigger nipping at the Lion's fins.
<Yes, likely.>
I know the long flowing fins can be attractive. Thanks for the time, Chris
<Have a nice weekend! -Steven Pro>

Compatibility, Lion and Grouper
Any thoughts regarding a small panther grouper (3 in.) and small lionfish (3 in.) inhabiting a 29 gallon tank together. I know they will both grow and am prepared to deal with that; however, curious as to your thoughts on how these two predators will cohabitate. Thanks.
<for a short time they will co-habitate (less than 8 months). The grouper ultimately feeds too fast and aggressively and will outcompete the lion... not to mention drastically outgrow it. My advice would be to simply keep one (the lion) and enjoy it easily for more than a year in that tank. Best regards, Anthony>

<Have seen these species kept together... often the bass will "steal" all the food intended for the Lion... and both/either get too big for a twenty nine gallon system. Need an eighty gallon plus just for these two fishes. Bob Fenner>

Cleaners (and Lions, Oh my!)
Hi
Are there any biological cleaners that will not be eaten by a lionfish? the
lionfish is about 5 inches long. Everything I see in my LFS are too small and will surely gobbled up before they hit the water. Thanks
<Always a gamble... but ofttimes if you can get the Cleaner/s into the system (as in initially hiding in the decor), Lionfishes et al. predatory fishes will recognize them as allies and leave them alone... Bob Fenner> 

Lionfish/porcupine puffer compatibility
Hello
Do you happen to know if my porcupine puffer (about 6 inches long) would pick on a lionfish?
<Yes... a very real, and frightening possibility. Puffers can tease, nibble Lionfishes mercilessly>
The volition type. NOT a dwarf lion. One of my LFS said the puffer absolutely would constantly pick on a lion, darting back and forth and nipping on his fins. Another LFS (just as reputable, if not a little more
knowledgeable), said the two would be fine together. All of my resources
(book wise) say nothing about keeping the two together, but most everything says lions are fairly docile, as are porcupine puffers.
<The operative term here should be "can". They can get along or not...>
And if it helps any -- the tank is 75g's and is fully cycled. It houses a 2'
3" peppered moray eel and a 6 inch porcupine puffer. I do 30% water changes every two weeks or so, and the ammonia and nitrite are zero, always. I'm very diligent about cleaning. :)
Another question, if you have time -- I lucked into my moray eel, and am
having a lot of trouble finding any info on them. I did find one page with a
few small paragraphs about him, but otherwise...no one seems to have heard of my eel. He's commonly called a "peppered moray," but the scientific name is "Siderea picta." He's got beautiful coloration, all white with tiny black speckles all over his body and light blue circles around his eyes. Very bold...not shy at all.
<Mmm, a very nice species... the name has been changed, to Gymnothorax pictus... you can find some info., pix on www.FishBase.org on this Muraenid... and in Scott Michael's fab v.1 Reef Fishes book... Bob Fenner>
Thanks, Bryce

Dwarf Lion
Bob,
I am sorry if it seems like I am harassing you I am just after info. I have found that the breed of dwarf lion I am wanting to purchase is Dendrochirus zebra (if it makes a difference). From what info you have given me in your last e-mail I am questioning whether or not to add the three spot damsels. I was going to add 5 or 6 because from what I have
observed they are quite small and I think they look quite neat in larger groups and I figured that if they were in a larger group they might take out all there aggression on each other, am I right on this or wrong? From what you tell me they sound like they like to be quite the trouble makers. If they are to aggressive what other breeds of damsels do you think would be better and would do ok with the breed of lion I have mentioned? I also
like the 3 and 4 striped damsels. I also had a question on another fish I currently have in my tank (actually he is the only fish, I am starting a new marine aquarium and it has been going great and is ready for fish). The fish was sold to me as a "worm goby", this sounded stupid to me so I looked up info on gobies and found that it was a "neon goby" the blue striped one, not the yellow. Is there any info on this fish you could give me?  What it eats? If it is good in a community or is it aggressive? All I know about it is
that it looks very healthy and it has been enjoying burrowing under the rocks and corals.  It will spend all day bringing rocks in and out of its hole it has made (is this normal?)  Thanks, John Moyer 
<< The Three and Four Stripe Dascyllus or Humbugs would be much better choices... the Domino, singly or in groups is a real terror at times... Really. Ounce for ounce they're amazingly bold... if they weighed in at a pound or more I wouldn't go diving with them.... They've drawn blood from biting me in service accounts... Okay, point made I wager.
The D. zebra is a great animal. It should do fine with more peaceable damselfishes... but do be sure they're large enough... for a small fish, Dwarf Lions have cavernous maws.
There is such fishes called Worm Gobies... and there are many species in the Genus Gobiosoma (neon gobies) that are blue-striped... What you most likely have is a Gobiosoma oceanops... it is not aggressive, is a cleaner organism out of the tropical west Atlantic (originally, but yours is likely tank bred/reared)... But they're generally not prodigious diggers... preferring to "perch" on hard substrates. Bob Fenner>>

Lions & Inverts
Bob,
Sorry, I forgot a question. On the ffexpress compatibility chart it says lions are compatible with invertebrates (spelled wrong, I know), is this right pertaining to the breed of lion mentioned)? Because all of the other sources I have been to say that lions enjoy munching on small fish, SHRIMP, and CRABS. I am confused. Can you shed some light.  Thank you, John
<< Hmm, well Lionfishes (subfamily Pteroinae, family Scorpaenidae) "are compatible with all invertebrates large enough for them not to swallow" is how I would have stated it... They will indeed swallow crabs, shrimps, even hermits... if they think they're edible and can fit them in their mouth.
Bob "the incandescent one" Fenner>>

Damsels & Lions
Bob,
I love damsels and lionfish both and I want to find some way of having them together. I was wanting to know, I know the larger breeds of lionfish will eat damsels in a bite, but what about a dwarf lion. Can a dwarf lion be placed with damsels or will the fish still make sushi out of the damsels? Thanks, John Moyer
<< As you say... "all is relative" when it comes to size of damsels and lionfish mouths... The latter are deceptively large! And there are even Damsels that are so feisty (and big) that they can bedevil a Lion! 
Some happy mediums do exist... See out nicer, larger Damsel species that are big enough to start with, and you can have something other than the dwarf species (there are several) of Lions... 
In fact, there is a genus of damselfishes that I really think ought to be a much bigger part of the marine aquarium trade, Amblyglyphidodon (a mouthful, I know). I recently wrote and sent in an article to the hobby magazine FAMA with a bunch of images of the three best species (IMO of course)... and have the piece and three pix posted at the URL: www.wetwebmedia.com if you'd like to have an idea of the sorts of damsels (there are over 350 species... presently) I'm talking about. These ones are beautiful stay out and about (instead of hiding), eat most any foods, but not coral polyps... Bob Fenner>>

Buying a Lion
I was thinking of getting a volitans lionfish. Would this be an alright fish for a 80 gal tank. And would it be safe with hermit crabs, snails, and shrimp? What other kind of fish would you suggest I put in with him? Thanks 
<<Probably okay with your invertebrates... might eat the shrimp if not enough cover for them to hide in. Most anything big enough to not fit in the Lion's mouth, and reciprocally not too mean to nip at the Lion will do (no triggers, big puffers)... 
Bob Fenner, who suggests you read over the survey pieces on marine livestock stored on the site: Home Page>>

Anemone crab/lion fish question
Currently I don't have either species in my tank as I'm waiting for my new 
tank to settle out the nitrogen cycle (I estimate another week until  nitrates are around 0). Anyways, I have a 55 gal and I am going to throw in an anemone or two. Clowns are neat but I think that an anemone crab would be pretty unique. knowing that anemone crabs are usually smaller and that lion fish will eat smaller inverts I was wondering it the anemone would be a good defense for the crab (assuming the crab wont leave the safety of the anemone). Lemme know, Jon Trowbridge 
<<A tough situation... can only give you about 50% chance that your Lionfish would not someday suck up the Anemone Crab...Bob Fenner>>

About the lion fish
Do you think a two inch long maroon clown fish will survive in a tank with either a 6 or 8 inch long volitans lionfish? Remember my tank is 120 gallons and 6 foot long. Do you think the lionfish will try to eat my damsel or will they do just fine and not get bothered at all by the lionfish?
Sincerely, Chris
<<It will/would be definitely inhaled/eaten. Bob Fenner>>

Fish
How can I protect my clown fish from getting eaten by my lionfish?
<<Large clown, small lion. Bob Fenner>>

Lion Fish 
Bob, 
I have a 120 gallon marine fish tank. My current stock is as follows: 
1 adult imperator angel 
1 4 inch powder blue tang 
3 yellow tangs 
1 4 inch Naso tang 
1 flame angel 
1 arch hawkfish 
1 blue damsel 
2 lemon peel damsels 
1 tomato clown 
1 blue streak cleaner wrasse 
I just added a 3 inch "nose to tail" black Lion Fish. Most of the fish 
seem to large, at this point, to be eaten, besides maybe the cleaner 
wrasse. Since I added the lion last, do I need to worry about any fish 
being eaten and if so, which fish? I have become attached to all my fish 
and this could mean the difference of whether I keep the Lion. I have only 
lost one fish in the year that I have had it up and running and I don't 
plan to start now with a poor choice. Thank you for your help, Doug 
<Not the Cleaner... it is likely recognized as a "friend"... but they (Labroides) rarely live in captivity in any case... see the rundown on these posted on the site: www.wetwebmedia.com.
The Damsels will be inhaled at some point and very possibly the Clown... but the rest should be fine. Bob Fenner>

Fwd: Lion Fish
Thank you for your help. One more question...what about the flame angel?
Does it have a fighting chance against the lion? Again, thank you, Doug
<Of a certainty yes... this is a smart fish that well knows what a Lionfish is all about... and quick to avoid being ingested. I give it good chances of cohabiting successfully. Bob Fenner>

The Lion's Den...
Hello again and your web site has been invaluable the past few days,
<Hi there! Scott F. here tonight>
I have a 55 gallon bow front with a magnum 350. My pets are a 10" snowflake moray, 3" crown squirrelfish, 3" red emperor snapper, 6" lionfish, and my personal favorite, a 7-8" panther grouper.
Yes, I know it is crowded! Yes, I Know it will get worse!
<Good- because you spared me having to tell you that! :) >
We got in this situation because we had to have the lion (Pterois russelli) because he is just beautiful.
<Yes- a lovely fish>
However, he is a hungry beast and ate all 7 damsels within weeks. So I decided to buy larger fish that he can not get in his mouth. 
<Well, there is a certain logic to that, but...>
This worked to some degree, but some fish (Huma Huma Trigger and angelfish) would eat the webbing between the lion's spines.
<Not a good thing>
Now my question is Can you suggest any fish that would go good with this lion. Preferably 2 or three tank mates. You have to understand, My wife absolutely refuses to have a tank with only 2 fish.
Any suggestions would be appreciated. Bryan Flanigan
<Well, Brian, I certainly understand your wife's feelings, but you really have to look at the situation from an objective standpoint. Conventional aquatic wisdom (and conscientious, responsible husbandry) dictates that an adult Pterois lionfish needs at least 40 gallons or more to just be comfortable. Just about any fish that you'd be able to squeeze into the remaining "available" space would be a snack for this fish. Also, these fish require very powerful filtration to deal with the large amounts of waste products that they produce. Water quality is a serious issue! This does not even take into account the psychological and physiological "toll" that life in such limited quarters will take on the animal.
Imagine you or I being condemned to life in a bedroom. Not good. When this fish hits full size (and he will), his 10 inch size will necessitate a very large, well-filtered tank. If you really love this fish (and I believe that you do), you must do the responsible thing and keep him alone in this tank, and then move him on up to substantially larger digs (with tankmates) in the very near future. I simply cannot recommend housing him with any tankmates at this point in the 55g. I think that your wife will understand this (and maybe consent to the larger tank?). Please research your future purchases through the resources on the wetwebmedia.com site. Keep reading and learning, and you'll make well-informed, responsible decisions in the future. Good luck!>
