I've got a really dumb reef stocking question (sorry!)    75 gal.; reading
I come from a freshwater background, and while I know that the inch per gallon rule is not accurate, I have also been taught that the smaller the fish is, the more that can be put into a tank of an equal size without it being overstocked.
<In general; yes>
Say in a 12 gallon tank, you cannot keep a 12 inch Oscar, but you CAN keep 12 2 inch neon tetras.
How does stocking work in a reef tank, though?
<Really, there are no "hard and fast rules" other than less is better. Some species are more aggressive, others better in duos/pairs, trios, groups... solitary>
I'm making out some tentative plans that revolve around a 75 gallon tank with a 20 gallon refugium (the current coral-only reef) and no skimmer for power consumption issues (though I may cave on the latter), and have been looking into stocking. From Googling and asking questions, though, it seems like people tend to be more concerned with number of fish than potential bioload that the fish would be putting out, advocating 5-9 medium-bodied fish (including deep-bodied fish like clowns or tangs, or high food need fish like Anthias), as opposed to a few groups of smaller fish.
My original -very high number- idea was a scooter (either red, or red wine-after the tank is at least a year old) a Firefish,
<Which species... see the Microdesmid coverage on WWM Re... again some better as ones, twos, groups>
a royal gramma, a pair of rusty gobies (Priolepis hiopliti), and then 5 each of masked gobies, tiger gobies (Tigrigobius macrodon), and 3-5 chalk bass.
<One; territorial>
 The Firefish, gramma, scooter, and chalk bass would top off around 3 inches, the rusty gobies about 1 inch, and the other gobies about 1.5
inches.
I asked a few people what they'd knock off of the list to make it work in a 75, mentioning my two biggest concerns were that I've read that the tiger and masked gobies share the same general territory, hovering near corals, and that I've read that chalk bass will sometimes eat smaller fish, and most of my gobies would be half their size and somewhat spaghetti-shaped. The knee-jerk reaction I got when asking questions, though, was "that's 20 fish in a small tank. You can kiss the thought of ever having anything but soft corals and high nitrates goodbye.
<Mmm; I disagree>
Take out half and you MIGHT be able to get away with it if you get a big skimmer." Even taking out half of the number itself, and leaving the largest of them, I can't imagine that 5 chalk bass,
<I'd only have one here... again, READ on WWM re the genus>
1 gramma, and 1 Firefish would have the same bioload as 2 clowns, 1 Bristletooth tang, a Chromis, and a trio of Anthias, correct? Is there an objective way to look at the stocking that does not just equate numbers to good stocking, or is that really the bigger concern in a reef?
<What you have listed should be fine; with honing the numbers of individuals down to 15-20. Bob Fenner>
Re: I've got a really dumb reef stocking question (sorry!)      11/24/16
I'd meant N. magnifica with the Firefish, sorry, I guess I was just thinking in common names for them. WWM says that they naturally occur in pairs or harems in the wild, though most of the hobbyist pages I have seen say that you'll usually end up with one, even if you buy them as a mated pair. Guess I'll scratch them from my list.
<I'd stock two... and make sure there are no holes for them to escape out the top!>
Mr. Jackson's article on chalk bass on your site mentions that "While singular specimens are seen, they are a social animal typically occurring in loose small groups of harems or shoals with a distinct pecking order."
<In a much larger space than you propose here. Four square feet is too little for more than one specimen>
and that it is best to add them in trios or groups of five if you wish to have more than one in a tank, so I had assumed that they would be more comfortable in groups. Will definitely take the number down to one of those max, though.
Thank you for the advice!
<Just stating what I might do given similar circumstances; glad to share.

Chlorodesmis/ DSB/ Jumping Prevention/ Echinaster starfish... reef stkg. f'   3/2/08 Hello again WWM Crew, <RA> Today I'm back with yet more questions that are dying to be answered. At the moment my tank is cycling, so I have been avidly researching species and thinking of different stocking plans. Anyways, here's a list of species I plan on stocking at the moment: Fish Paracheilinus filamentosus(5) Nemateleotris magnifica (pair) Stonogobiops nematodes (pair) Cirrhitichthys falco(1) Inverts Nassarius distortus(8) Cerithium sp.(10) Trochus sp.(5) Alpheus randalli(1) Algae Chlorodesmis fastigiata Possible Additions Cirripectes stigmaticus(1) Stenopus hispidus (pair) <Not with the Hawk> Echinaster sp.(2) Halymenia sp. The tank is an 86.4g (48"L x 16"W x 26"T) with an approx. 2" sandbed and 125 lbs of liverock. I plan on having the Chlorodesmis grow on all of the liverock and having that instead of coral. My questions are: 1. I'm interested in herbivorous blennies. Would any edible algae grow if I have Chlorodesmis (lack of nutrients + allelopaths)? This is also a concern for my snails. <Likely to be consumed> I'm interested in having a remote DSB. 2. Would a DSB slow the growth rate of the Chlorodesmis (competition for nutrients)? <Yes> 3. What is the purpose of having worms, mini stars, etc. besides to aerate the substrate? <For your enjoyment, to complete closed processing of foods...> 4. If I don't get any of the "Possible Additions", will this setup really produce enough waste/nutrients to support both Chlorodesmis and a DSB? <Maybe> 5. I know that wrasse and Firefish are prone to jumping. Are they too thin to be stopped by eggcrate? If so, what should I use? <The eggcrate should work> 6. Could you please identify or at least give me some general guidelines for this Echinaster species on http://liveaquaria.com/product/prod_Display.cfm?pCatId=581? I'm really interested in it. <"Page no longer available"... likely care is identical per the genus, Order... covered on WWM> Well, that's all I can think of right now. Thanks for reading. TIA, Random Aquarist <And you for sharing. Bob Fenner>

Moving Up'¦to a Larger Tank  2/28/08 WWM Crew, Your website is very well done, and extremely informative. <Thank you.> I've been reading your site for a couple of months now trying to figure out what I want out of my reef system, or better yet what I want to go into my system. Here is what I have currently, a 20 gallon tank with a wet dry filter, 2 power heads with an under gravel filter, 20 lbs of live rock, Corallife 50/50 65watt bulb & fixture. Inhabitants include, 1 lawnmower blenny, 1 sgt. major damsel 1 pink tip Haitian anemone 1med/large grape Caulerpa plant, a mix of snails and hermit crabs, 1 cleaner shrimp, and 3 peppermint shrimp. I know it sound like a lot but all of this livestock is pretty small. Which brings me to my next point. All of this livestock is small now, but will quickly out grow my tank. <Quickly being the operative word.> In about a month or so I am going to start up a 72 gallon bow front tank and slowly transfer everybody over. What I have been searching for is maybe a list or something of the sort of what kind of livestock, specifically, can I put in my new tank. I know that this is a broad question, and nothing in life is a sure bet. However, I need a shove in the right direction. First of all, I noticed that a lot of people have a different opinion of just exactly "reef safe" is. What exactly does "reef safe" mean? Does it mean: everybody gets along in the tank from fish to corals to all invertebrates, or does it mean most everybody gets along, with the exceptions of a few critters who like to take samples of their tank mates or just as long as nobody samples the corals, mushrooms, etc. everything else is fair game. <Both definitions fit. What some consider reef safe may pick at inverts depending on the individual fish. Others are considered reef safe so long as you don't have certain inverts in your tank (such as the shrimp). To be truly reef safe in my opinion, all should get along.> I think you know what I'm trying to say. What kind of fish can I put into my tank that will not harm my shrimp, any future corals, my anemone, or chow down on my snails or hermit crabs. <I hear you.> The new tank will have plenty of light for new corals and my anemone. <Be aware it is not a good idea to mix these.> I have taken a whack at a few fish that I am considering; please tell me if they would make good neighbors for what I already have. 2 Hippo Tangs <This tank is really still too small for these. Tangs require a good amount of swimming space.> 1 Magnificent Rabbit fish <These get fairly large and fall into that hit and miss reef safe category.> 2 False percula clown fish <Not a problem.> Any other suggestions would be greatly appreciated. Steve Harris <Keep reading, research each addition thoroughly as you stock this new tank. A few links are included below to get you started, Scott V.> http://www.wetwebmedia.com/rabbitfi.htm http://wetwebmedia.com/paracant.htm

Moving Forward To My Last Fish Choice and Some Corals -- 02/28/08 Eric, <<Hey Danny>> I'm looking to make my stocking plan for corals. <<Okay>> Here's my system and what I've got today: Equipment: 65g tank 36" x 24" x 18" with about 85 lbs of live rock Protein skimmer Canister filter with carbon Red Sea Ozone generator with ORP controller & probe (set to 360mv) 2x 150 watt 20,000K MH Fixture along with a T5 with 1 actinic and 1 daylight bulb combo and two 1-watt moon lights 2 Koralia # 3 power heads (850 gph) Fish / corals: 1 Solar wrasse (doing great, eating like a pig!) <<Yippee!>> 1 Sixline wrasse 1 Royal Gramma 2 Tomato clowns 2 Ricordea (mid-sized) 6 small assorted mushrooms <<These last two can quickly become 'many' and take over the tank, if left unchecked>> 1 Leather coral, I think is a Lobophytum 12 assorted snails 1 Cowry 2 Emerald crabs <<Can/will become dangerous to other livestock as they get large (and they do get large, possibly to 4' across the carapace)>> 6 blue-legged hermits I would like to add a Flame Angel, <<Your tank is a borderline too small for this fish'¦in my opinion>> a bubble tip anemone <<Mmm'¦not recommended with sessile inverts/mixed with noxious soft corals'¦especially in this volume of water>> and some LPS or SPS over time. I know I may be pushing the limit <<Indeed>> but many of the LFS' I go to seem to think it could work if I give the right space and run carbon. <<But'¦for how long'¦>> From the fish books I have and all the reading I've done on WWM, there seems to be no definitive answers. <<Ah well, Danny'¦tis true'¦but then the hobby is not 'black and white' but rather; oh how do I say it'¦ a system of 'balances''¦ The equilibrium or 'balance' of your system is affected by many factors (size, equipment, maintenance practices, husbandry skills, stocking selection/levels, etc.), and one way or another, these factors limit what can realistically be accomplished for the long-term (and you should always consider the 'long-term' when planning/stocking your system). Right now, I think your most limiting factor is the 'size' of the system. You enjoyed a measure of success (and some luck [grin]) with the addition of the Solar Fairy Wrasse, but you are leaning towards upsetting the balance of your system with some of your proposed new additions'¦in my opinion>> As you know from my recent wrasse experience I'm willing to go the extra mile to make things work but there's only so much one can do... <<Yes'¦ Must work within the limitations of what you have>> So I was hoping you could provide some sound guidance that would help me make realistic choices. <<I've given 'my' viewpoints>> I also provided a photo... Danny <<I see it'¦and there's that beautiful Cirrhilabrus solorensis in the foreground. Cheers mate, Eric Russell>>

What Do I Put In Next? (Reef Stocking Questions) -- 02/27/08 Hi all, and thanks. <<Hello'¦and welcome>> Without this site I doubt I'd know as much as I do now'¦ <<I know I wouldn't!>> After saying that I'm going to tell you what corals I have. Don't yell at me... <<Um'¦okay>> A friend of mine gave me a couple. <<And twisted your arm to make you take them? [grin]>> The tank's a 92 gal corner bow with a 30 gal sump, a 30 gal refugium, 6" deep sand bed and algae. <<Sounds good>> The tank is doing great - lots of macroalgae and little bugs on the glass. Here's what I have. 1) Pulsating xenia 2) Leather tree 3) Star polyp 4) Green mushrooms O.k. so far so good'¦ All soft yes? <<yes>> Now the bad. 5) A small frag of Blastomussa? (I know LPS) 6) Frogspawn (small) LPS OK how bad is it? <<Not 'too' bad at all'¦and quite common within the hobby yet to create/keep this 'reef garden' type of mix. Do be sure to employ some chemical filtration and a good quality skimmer>> Do you think they'll be alright, or will I have problems? <<With proper spacing/separation to prevent physical contact, along with the awareness and good husbandry/maintenance to deal with the inherent problems of such a mix, it is possible to keep these animals together>> What will I have the biggest problem with and why? <<My opinion'¦the softies'¦and due to their noxious nature/ability to malaffect the entire system very quickly>> What would you do? <<Add some purposeful chemical filtration'¦perhaps carbon and/or Poly-Filter in a canister filter>> My friend also gave me (again don't yell) ;) A beautiful rose bubble tip anemone with a built-in Clarkii. It's awesome! <<Mmm, no doubt'¦and entirely unsuited to this mixed bag>> And 2 clams a maxima and a Crocea. <<Can/will be very susceptible to poisoning from the 'softies'>> 7) Feather duster 8) 2 peppermint shrimp. 9) Assorted snails, emerald crab, 5 small red legged hermits. I also need to know what order to put my fish in. Here's the list of what I would like. Please let me know your opinion as to what are good/bad and your reason. <<Sure>> 1) Powder blue tang <<Not a good choice. Needs a bit larger system'¦these fish seem very susceptible to environmental stressors which usually manifest as protozoan infections. The Yellow Tang (Zebrasoma flavescens) or Scopas Tang (Zebrasoma Scopas), or a smaller Ctenochaetus species like the Kole Tang (C. strigosus) would make for better/much hardier additions, in my opinion>> 2) Angel coral beauty <<Beautiful little fish'¦and the Flame Angel (Centropyge loricula) would make a good alternate selection>> 3) Fridmani Pseudochromis 4) 3 small blue Chromis 5) A goby- which would you recommend- a diamond, tiger watchman or yellow watchman (or would a red spotted blenny be better) I just want something to help clean the sand. <<Mmm, is up to you'¦though this can be a two-edged sword as these animals are quite prone to large disturbances of the sand bed that 'can be' detrimental to the function/performance of your DSB>> 6) And if there's room, maybe a couple of Banggai cardinals. Again, what order should they go in? <<I would add the Tang last, with the Pseudochromis and Angel just before'¦and the rest before these, though in no particular order>> Thanks again for all your wisdom and expertise. <<Happy to share. EricR>>

Marine Aquarium Help... stkg., reading   2/23/08 Hello, my name is Ray, and I am a relative amateur to the marine fish keeping world with only a couple of easy species to keep under my belt (Volitans lion, snowflake eel). I have a few questions about my 125 gallon aquarium. The tank is currently stocked with ten Chromis viridis, one Amphiprion ocellaris, one Nemateleotris magnifica, a couple blue-legged hermits, margarita snails, a pair of serpent stars, a pair of urchins, a sand sifting star, and a peppermint shrimp. My first question pertains to stocking given the livestock in the tank, would 4 Serranus tortugarum, one Gramma loreto, one Opistognathus aurifrons, 2 Sphaeramia nematoptera, 2 Pterapogon kauderni, one Centropyge bispinosa, one Siganus vulpinus, one Pseudocheilinus hexataenia, 2 Gobiosoma oceanops, possibly one Synchiropus splendidus, more peppermint shrimp, serpent stars, hermits, snails, and possibly a bubble tip anemone coexist together? <Mmm, likely so... though the Anemone may consume the Mandarin... and the Lined Wrasse can become bullies to other rock-inhabiting fishes. But otherwise, I give you good odds here> The tank has been running for about six months and has two pieces of live rock in it, and I plan to add more. The other decor is lava rock <Do read on WWM re this... some types are unsuitable> set up in cave formation to enable territory set ups, and plastic corals. My other two questions are small: can cured rock bought from my LFS go straight into the tank (after cleaning to remove mantis shrimps and the like) <Mmm, sometimes... best to isolate, re-cure, examine for pests for a few weeks yourself...> and are there any plants (such as mangrove, kelp, or shaving brushes) that could escape the attention of the fish? Thanks a million, Ray <Sure... can be read about in articles, FAQs files on WWM. I'd give a read re all the life you list, are considering... re Systems, Compatibility, Feeding... there. Bob Fenner> Re: Marine Aquarium Help, reef lvstg. f'  2/23/08 Thank you very much. Originally I had planned to have a group of 3 of the Firefish gobies, <Better with two of this genus in this sized volume> but I bought one on an impulse buy without enough money to buy the rest of the group and don't want to get a group unless I can introduce them simultaneously. <Can place another for the two> The wrasse was not in the original line up either, but I am thinking about it because I discovered some small white bristleworms in my MagFloat algae scrubber. (Your sight says they are harmless/beneficial but I don't want them to get out of hand.) This is my first large tank and I'd like to be able to enjoy it before I go off to college this September. Again, thank you. <Welcome! BobF>

Stocking a New Reef System 2/21/08 Hi, <Hey there! Scott F. at your service!> I wonder if you could please give me some advice. I have an Oceanic 92 gallon bowfront corner tank. This is stocked with approx 90 lbs of live rock and very little else at this point. The tank is ready to start to be stocked and I am considering my options. I want to keep it as a reef tank with corals and so my fish options are what I am concerned with at this point. My coral options will be, initially, corals on the more hardy end of the spectrum to gain experience. I am researching these now. I'll be looking at soft and leathers, mushrooms etc. no hard corals. <Nothing at all wrong with that approach, IMO! Soft corals are interesting and beautiful.> On the fish stocking I would like. A Kole Tang, A Scarlet Hawkfish, a Chalk Basslet and a couple or three Engineer Gobies. I would also like a Lemon Peel Angel but am I overstocking? <You'd be pushing it, IMO. I would omit the Angel. More importantly, the Lemon Peel, although one of my favorite fishes, is a potential coral eater/nipper, so you need to be aware of this. Other than that, I have little to criticize in your stocking plan!> I think this seems OK but would value your advice. <And we value your visits to WWM!> In addition to the basics I have a 300 gph pump ( 4 foot rise - 1 inch tube for in and out feeds) - a Fluval Turboflotor 1000 protein skimmer, an FB600 fluidized bed filter and a 3 powerhead wave system (Wavemaster pro). Ian <Sounds like a plan, Ian! Good luck! Regards, Scott F.>

Stocking a New Reef System for Long-Term Success  -02/20/08 Hello <Hi there! Scott F. in today.> Thanks for all your help in the past. I am still in the planning stages of my setup. I have a 150g dual overflow oceanic AGA. This will be a full reef setup. <Sounds nice!> Next to it slightly lower will be a 150 refugium with a DSB LR and Chaeto. One of the overflows from the display will feed the refugium. <A good plan.> And the other will feed the sump which will be under the tank. The sump will have a large protein skimmer still looking at brands. I have all of that set up and I think I'm ready to go. <Exciting!> Now my stocking questions. I will be transferring the fish from my current 30g reef into this tank and using the 30 as a quarantine. The current stock: Cherub pygmy angel (Centropyge argi) False Percula clown (Amphiprion ocellaris) 2-green Chromis (Chromis viridis) possibly add 3 more skunk cleaner shrimp (add 2 or 3) Blood shrimp ( add 1 or 2) Peppermint shrimp (add 3 to 5) Small Blue Leg hermits 1 Turbo snail I want to add to that McCosker's Flasher wrasse (Paracheilinus mccoskeri) Diadem Dottyback (Pseudochromis diadema) <Can be a nasty one, make sure that you add him later in the stocking plan, and provide plenty of hiding places.> Either a psychedelic or green Mandarin ( Synchiropus picturatus, Synchiropus splendidus) mated pair if possible Is there much difference between the two other than looks? <There is not much difference between the two from a behavioral or husbandry standpoint, in my experience. Both require steady supplies of living foodstuffs, such as copepods and amphipods, to live healthy, happy lives. In a new system, I'd be a bit hesitant to add one. Give it several months to establish significant populations of beneficial food organisms.> 5-7 purple queen Anthias (Pseudanthias sp.) Purple Firefish (Nemateleotris decora) Possible another pygmy angel but I do not know if I want to take the risk <It is a risk. However, if you are bringing the current Angel into the new aquarium at the same time as the new one, and if there are sufficient areas for the fishes to establish territories, AND if you choose a specimen comparable in size, AND if you are lucky...it could work. It's a real dice roll.> Suggestions on type? <I suppose that I'd go with another Cherub.> Nassarius snails a few more Turbos That is my fish list I have not finished my coral list but do you see any problems with this? <Other than the caveats mentioned above, I don't see any major flaws in this stocking plan.> Also do you think my refugium will be enough to feed most of the tank I don't fully understand with the 1 to 1 ratio if the tank would be almost self sustaining? Keith Fontes <I think that once you get the system and refugium established, they will work well together, supplying supplemental food sources for the inhabitants of the aquarium. It will take a number of months for this to happen, however. Patience is required. In the mean time, you'll have to feed your system regularly. If you really want to create a "rich" population of living food sources in the system, consider seeding the system with populations of desired animals, and wait a month or two (or more!) before stocking with fishes! Most hobbyists would be hesitant to do this, but it is a great way to get a "head start" on the production of living food sources for your system. I've done it, and it works well! Best of luck with the new system! Regards, Scott F.>

75 Stocking, reef   2/8/08 Hello Crew: I wanted to get your opinion on some stocking. I have discovered via trial and error that small fish are the way to go in my 75 gallon reef. I currently have Leathers and Zoas along with some Green star polyps. I have tried all sorts of fish and am happy to report that I have found excellent homes for all of them using my local reef forum. I now have 2 Percula Clowns, an Orchid Dotty Back, a Banggai Cardinal, a Yellow Watchman Goby, an Algae Blenny, and 2 Blue Green Chromis, the third was the odd man out and didn't make it. I think I have room for a couple more Chromis and would like to bring the school up to 5 or 7, I also would like to add a couple Firefish. Based on my reading on the site I think 4 would work but I am not sure if I have the room. <You do> I would like to keep my tank on the "under stocked" side and am not sure if I am pushing it. The other option I have thought of is additional Cardinals but my boy is 2 years old and I am afraid that he will not take well to the new comers. Any advice would be really appreciated regarding a good final stocking level with additions of Chromis, Firefish, and potentially Cardinals. Thank you so much for all that you do and for the advise you give. Regards, Craig <What you propose should be fine... I would leave off with other Banggais as well. Bob Fenner>

What Fish Next? Reef stkg.     2/8/08 Hello WWM Crew! <Ashley> We have recently moved up to a 40 gallon breeder tank from a 16 gallon tank and added a Crocea clam. <I assume you upgraded lighting also.> Currently, we have a Percula (not a true), 2 Chromis and a Mandarin Goby (I promise he is well-fed with copepods I add on a regular basis). <This will get expensive and not be a viable long term solution; this fish does need a larger tank.> Over the next year, we were hoping to add one, possibly two more fish. I dearly love the clam, named him Mick Jagger, and don't want to add anything that would harm it. <You have to love that name for a clam!> I have read through much of your archives and would love to hear any recommendations you have. Here are the questions... Are there any Tangs you would recommend that would stay small enough for our tank? <No> We originally, before the clam, had planned on a Flame Angel fish since it is from the Marshall Islands where I lived as kid, but I see it gets mixed reviews especially since we want to add corals eventually. <Yes, sometimes they work out fine in a reef, sometimes not so.> The LFS recommended a Six-Line Wrasse, are there any other Wrasses that you might recommend? <Maybe a Fourline wrasse, Pseudocheilinus tetrataenia But, I would skip the addition of either, they will quickly outcompete the Mandarin for food.> My husband thinks he wants a Foxface, but I think it might be a bit big and a coral nipper? <Yes, too large for this tank and can be a nipper.> Thank you so much! The information you provide is enormously helpful and appreciated. I was saved several times from purchasing some less than adequate equipment for the new tank setup thanks to all of you sharing your expertise! Ashley Nocks <Welcome, happy reefing, Scott V.> http://www.wetwebmedia.com/linedwrascompfaq.htm

Reef Stocking Levels/Compatibility 2/6/08 The happy place A question for the fish gurus, but first what I have in the tank. I have a 75G Reef tank with many corals soft to hard, 2 anemones (one Maroon Clown houses both), and 4 types of mushrooms that are practically growing out my ears. As for fish I have a Blue Tang 5", <Why cap the "Blue Tang" and not the rest of the fish names??> Lawnmower Blenny 3", 4 cardinals 2", Potters Angel 3", Maroon Clown 4", corus <Coris> Gaimard Wrasse 5", Serpentine Starfish 1'+ tip to tip, 2 urchins, some hermmies, some snails, and last but not least a 24" Snowflake Eel. <Yikes, at the size these fish are, you are very overstocked, problems coming.> I bought the Corus <Coris> wrasse about 10 ago, along with a second maroon that just went back in trade for the Potters Angel. The maroons did not get along at all even though they were put in together. I figured this would happen but it got too bad. <Geez, why do it if you knew what the results would be.> Back to the question. The wrasse did laps out front for about 4 hours, then dove in for bed. Came back out the next day and was out all day and part of the night. Came out again the next day for about 6 hours and I have not seen him since. He did get some Mysid shrimp before he vanished but it has been about a week since I have seen him. <Did you look behind the tank. on the floor and/or elsewhere. They are notorious for jumping...if your tank is not covered.> The second maroon I had was a real troublemaker and went after every fish in the tank. He only really attacked my other clown though. <Yes, are semi aggressive.> I don't think the eel or starfish would have got him. <I wouldn't rule this out (starfish), especially a one foot specimen.> I have had the tank up like this for 8 months and no loss of any fish, big or small. The eel gets plenty to eat as does the star. The only thing I ever lost was a Seahare to the star (expensive meal). What are your thoughts on this corus <Coris> wrasse? He has got to be about ready to start his color change as others his size I have seen are just starting. Would this have anything to do with it? <Nope.> Everything else in the tank is happy and out front swimming all day long. What do you think??? <I think your tank is too small to house that many fish at the size they are, just increases aggression. High organic waste levels can also be expected. The Coris Wrasse needs to be in something like a 100 gallon tank and not kept with invertebrates. Hermit Crabs, snails, etc, will soon disappear. You may want to read here on this fish. http://www.wetwebmedia.com/marine/fishes/wrasses/coris/gaimard.htm James (Salty Dog)>

Moving to a Bigger Tank, reef... stkg., set-up  2-1-08 Hi Bob, <Do I look that old? ;) Mike here today, Bob is having a beer (if he's lucky...)> Fantastic site with a TON of great information. <Yes it is, thanks> I Currently have a 56 gal with LR/LS, NO coral, a few inverts (snails, arrow crab, choc chip star, and emerald crab) and of course fish. We just bought some more fish for the aquarium last week knowing we will be buying a 125 gal this coming week. The fish we have are 1 Banggai cardinal, 1 PJ cardinal, 1 maroon/gold clown, 1 blue hippo tang, and the new additions are 1 latticed butterfly, 1 coral beauty angel, 1 Twinspot goby, and 1 red knobbed starfish. <Banggai's are schooling fish, might want to get a few more of these guys> A lot for a 56 gal tank, <Too small for the tang, that's for sure> I really should have waited to get the new guys. Everyone is doing fine, but I want to keep the ball rolling on getting them into their bigger home. <Good idea> My question involves setting up/cycling the new 125g tank. First of all, let me mention that we are not currently happy with our current substrate (Florida crushed coral) from a purely aesthetic point of view, and want to add sand to the new tank, which I'm sure the new Twinspot will love more than the coral. My LFS suggested that with adding the new LS, my existing as well as some new LR, and also adding a live bacteria product, that I could move the fish over after 24 hours, and if I wanted to wait 1 week and monitor the water that would be better, but after 1 week it was fine. I have read the articles here on establishing the bio filter and cycling, and that time period seems a little short to me. I really don't have the space to maintain both tanks for long, but when it comes to the health of my "babies" I can manage for a couple weeks. Do you think adding what I have mentioned above, and waiting about 2 weeks and monitoring the water quality will be long enough? <Yes, as long as all the param.s read appropriately...should anything go awry, Amquel+ is a lifesaver. Make sure your skimmer can handle the larger water volume, and if you don't have a skimmer, get one> Also, they advised that by adding all three items, LR, LS, and live bacteria, that I really wont see a fluctuation in test numbers in terms of ammonia and nitrites. What SHOULD I be looking for to know that the tank is truly ready, an increase in Nitrates? <If your ammonia and nitrites are zero, you can safely add your livestock. Monitor your water once daily for any ammonia or nitrite spikes (possible but not likely) and dose with Amquel+ or Seachem Prime to neutralize (assuming your animals are present)> My last question is, will moving the decor and LR to the new tank, and basically leaving my livestock in a bare tank with substrate be detrimental to them? Should I leave a couple decorations and a big piece or two of LR in there until the move? <I wouldn't even split the two - you should be fine adding the LR and fish at the same time. The LR is what's performing your biological filtration in your current aquarium anyway (unless you have another biological filter you didn't mention) and it will continue to do so in your new aquarium. Add your sand to you new aquarium, fill with saltwater of the same temp/salinity/pH, and add your rock and animals - just see above re param.s> Sorry for so many questions, but I want to do this the right way and not over stress them. <No problem> Thank you again for such a great site and great information. <Anytime> Mike Parker <M. Maddox>

Compatibility/Acclimation 1/23/08 Hello crew, <Hello> I know that you hear it a thousand times a day, but it's still worth saying. You are the go to site on the web for information. Any time I am ever tempted to get a fish/coral/ invert, I always check out what you have to say about it first. As you have mentioned not every published person is even remotely correct on certain issues; (granted there is always some range within what is true). Anyway onto the questions: One of my tanks is a 30g mixed fish/reef. It has been up and running for 9 months now and doing well since I added the Remora pro skimmer- lots of hair algae before that now zero. Currently residing in the tank are: False Percula Clowns Coral beauty- not a nipper :) Blue damsel CBS <Coral Banded Shrimp?> Hawaiian Shrimp (Saron marmoratus) And various sps, LPSs, soft corals I feed the tank a varied diet at least twice a day and all my parameters are within acceptable ranges. My question is this, who bit the Coral Beauty? <I'm betting on the Blue Damsel.> If not as soon <?> as the bite out of the tail fin healed, another two circular bites appeared in the same location. I would assume that it was the damsel because of their notorious reputation but... Lately the clowns have been hosting a Goniopora. (I know, hard by itself, even harder with the pestering of clowns- I have noticed a bit of recession after two months) Anyway, the female has become quite protective of it's host. Is it likely that the clown could be the culprit? <Both, as you say, this coral is difficult to keep without the Clownfish agitating it. You do not mention your lighting and this coral requires very high light levels to survive, and even at that, most will not survive long.> Or should I go ahead and remove the damsel and see where it goes from there? The reason I ask is because I have never seen any aggression between any of the tankmates. Even when I first added the Coral Beauty two months ago, I saw no signs of discontent. Why all of a sudden? <With you being in front of the tank, it could change the mindset of the damsel, more concerned with you than the Coral Beauty. I'd remove the damsel.> Second question: after reading the explanation of the two ways to acclimate fish and inverts- normal and "guerrilla" I guess- I am still left with one question. What is the purpose of acclimating a specimen to your exact pH, salinity, etc. if you're just going to put them in a freshwater/ Methylene blue dip for five minutes? Are you suggesting to just jump to the dip after temperature acclimation? <I do not strive to match the pH and other parameters exactly. A pH within .1 is fine along with an SG within .001 is fine. Temperatures can be within a degree. As far as the freshwater dip, I'm really not a fan of dipping a perfectly healthy fish. Why put it through unnecessary stress, much better to quarantine a new specimen and treat only if needed. As far as acclimation, I prefer the drip method. This type of acclimation will slowly adjust all the water parameters within a safe time frame with no need to manually adjust the shipping water. There are inexpensive kits on the market now for drip acclimation.> Thanks for your time <You're welcome. James (Salty Dog)>

Re: Compatibility/Acclimation 1/23/08 Thanks for the quick reply. <You're welcome.> Will remove the damsel... not that it'll be anything but impossible- I'm thinking a fish trap. Not that it really matters but I'll tell you anyway. <Yes, never easy, one reason why I research everything before I buy, because once the fish is in...you know the rest of the story.> You mentioned lighting requirements for my Goniopora. I have a 30g high with a 4"dsb so the substrate level is essentially 20" deep. I am keeping the Goniopora right on the substrate. Lighting the tank I have a 150w HQI MH and 64w actinics x2. So this tank has 278w/ 30g= 9.2w/g. Granted this is a lot of light, but it has to go quite the distance to reach the Goniopora. <Should be fine here with lighting. James (Salty Dog)>

Marine Stocking Questions 1-22-08 <Hi there Danny, Yunachin here.> Basically I'm new to having a saltwater aquarium and I'd like some help with my fish selection. <Welcome to the saltwater hobby!> Here's my set up: 65 Gallon tank, with a Filstar-2 Canister filter, Protein skimmer, 2 power heads for circulation, a heater, 2 150w 20,000K metal halide light and a T5 Actinic. <Nice.> Inside I have about 70 lbs of live rock, some Tonga some Fiji and Vanuatu mixed and I am planning to go with a glass bottom. <If you plan on having any type of corals in your tank may I recommend some aragonite versus a glass bottom. Aragonite helps buffer to an extent and can also help in the long run with denitrifying your tank and helping improve your water quality.> I'm about a month in and am cycling with 2 Damsels (a Princess and a Yellow tail) 8 hermit crabs, 8 Trochus snails, and an emerald crab. As well, I plan to have a reef set up with some LPS and either SPS or Softies in the future. <Here are some links for some great beginner corals: http://www.wetwebmedia.com/trachyphlliidae.htm ; http://www.wetwebmedia.com/clavulariids.htm ;> In addition to the 2 Damsels, the stocking list I would like to build up to over the next 6 months or so is a 4 or 6 line Wrasse, 2 Percula Clowns, and for my feature fish, a Kole Tang, Flame Angel or Copper Band Butterfly Which of the 3 would you recommend, or do you have any better suggestions for something in the range of 5" - 8" that would fare well in my tank. <First I do not recommend a Copperband butterfly due to the fact that getting them to eat is a very difficult task. Flame Angels are gorgeous but can be nippers of coral so you would have to watch when introducing him into your tank. Also watch for aggression and combat it by having caves and such for him to retreat to if need be. A Kole Tang would be okay to add to the tank if you choose and here is a link to check out some more information : http://www.wetwebmedia.com/ctenocha.htm ;> I have also been told that the Damsels are not the best fish, would you recommend change if I were to find them a new home? <Damsel fish can be extremely aggressive and because they are in the same family as clowns I would recommend removing them before adding clowns to avoid any aggression and possible deaths. It is amazing such tiny beautiful fish can have such little attitudes. Good Luck on the new set-up! --Yunachin>  

R3: Lighting For 65g Biotope Shallow Reef Clam Tank (But Not 'Really' A Biotope'¦Bummer) -- 01/19/08 I'm following along so far! <<Excellent!>> **Ah! A convert'¦** No conversion from me...

Bookmarked as well. <<Beautiful and comparatively peaceful wrasses...and not unknown to help with pest organisms (flat worms, Pyramidellid snails, etc.)>> **Of concern'¦re the inclusion/addition of the anemone** Understood.

Don't misunderstand me, I think an anemone with symbiotic Clownfish make for a beautiful and immensely interesting display'¦I'm just stating that in the best interest for all, the tank and its other inhabitants should be geared toward/designed for the anemone>> **Ah, putty in my hands [grin]. But seriously, as much as I like my own opinions, do seek out information from other sources as well, and use your own good judgment to make your decisions** LOL'¦noted. Don't worry; I won't listen to you too much. <VBG> don't go getting a big head or anything. :-P <<Ha! Too late'¦!>> I will ultimately decide for myself after consideration of various viewpoints. <<Ah good'¦>> **And more simple to research** Infinitely more simple, which is a relief. **If you do this (add an anemone), I recommend allowing the Cnidarian to become acclimated/hardened before introducing the clowns as they can be pretty rough on a newly acquired, and therefore stressed, anemone** This seems to be the 'majority' opinion I've come upon, although I do read of the opposite, too. <<No doubt>> It seems sensible to add the more sensitive creature first so that she can adapt before being beaten up. <<Indeed>> **Indeed'¦ Do read-up on our site re 'cleanup crews''¦but when utilizing a DSB I am partial to the small burrowing and detritus feeding snails such as Cerith and Nassarius species. The smaller Brittle and Serpent stars are very good detritivores, but can become hazardous to smaller fishes if/when they become large'¦and do avoid the Green Brittle Star altogether (genus Ophiarachna). Many folks also employ supposedly reef-safe crabs ('hermit' or otherwise), but I don't, as I feel they are 'too' opportunistic in their feeding habits** Another member of the Crabs are Evil Society'¦ <<Mmm'¦yes, I suppose so'¦but not without reason>> I've sure noticed that not many people want to keep them in their tanks. <<Actually, my experience is just the opposite'¦most any reef hobbyist I know keeps crabs of some form>> They are fascinating critters, though, aren't they? <<Oh yes!>> Thanks for the suggestions. <<Welcome>> **Excellent my friend** I'm just not feeling the Allelopathy today, so it's on tomorrow's menu. Lack of sleep caused by my kitty not feeling well during the night. Oh well. <<Can sympathize'¦mine thinks he needs to get me up at 3am every morning because 'he' is hungry>> **Ah, I see now'¦still marginal for halides I think** Agreed. **Okay'¦do fit 'as many' bulbs as you can. And keep the addition of bulbs in the short-wave (Actinic) spectrum to the very minimum** I'm starting with a 6x39 Tek Retrofit, with this bulb sequence: 2 - ATI Blue Plus, 1 - ATI True Actinic, 1 - ATI Aquablue, 1 -UV Lighting AquaSun, 1 - GE 6500K Daylight. After measuring I'm concerned that eight won't fit. If there is room remaining I will order up two more. <<Okay>> How's the bulb choice? <<Too much 'blue' in my opinion Utilizing more bulbs with a lower Kelvin rating will give more output/provide more useful light spectrum'¦something I think you will find important to your SPS and most definitely to any anemone you try to place under this lighting>> I had a lengthy conversation with the lighting guy (reefgeek) and this is what he suggested I try for what I would like to keep. <<Apparently we disagree [grin]>> Thanks, again, Eric... We are currently getting about a foot of snow. Fun! Barb M. <<Always welcome, Barb. We to are supposed to see some 'white stuff' (about an inch), but temps are in the 40s so I have my doubts.

Planned for. <Excellent> ** No doubt, and you're about to get another** That's why I wrote! :) <<Hope you found it useful>> **Mmm, well'¦so much for the biotope'¦** I'll say the dreaded phrase; "from what I've read". I read about this style of tank in John Tullock's Natural Reef Aquariums; Simplified Approaches to Creating Living Microcosms. <<Hmm, my reference/hobby books are currently packed-up (in the middle of renovations)>> But, as I've just opened the book I see I've mis-stated myself! Oh, geez. <<Oh?>> Well, here goes: It appears I have mixed up my purposes (but you knew that! lol)... this approach is called in the book "An Inshore Aquarium for Clown-fish". <<I still gotta say, I just don't think mixing corals/clams with an anemone is good practice unless the tank is very large (hundreds of gallons) and the other invertebrate life well established (hardened), and the anemone is suitably isolated/separated from the sessile animals'¦and even then, best left to experienced hobbyists. If you really want to have that 'symbiotic' experience'¦I recommend you study up on the species of anemone you want to keep (some are easier/better suited to captive life than others) and set up a tank just for this'¦along with a pair of the proper species of Clownfish>> I think with all the studying I'm doing my brain has become very confused. <<Perhaps a quiet moment with a glass of wine is in order'¦>> Here's what he suggests. Let's see if you agree with the approach: "for a smaller system" he suggests a pairing of tank-raised Amphiprion clarkii clownfish and a Macrodactyla doreensis. <<Good choices'¦though there are other suitable; and in my opinion more attractive, Clownfishes that can be kept with this anemone>> Other fish he recommends: Mandarin fish- Synchiropus splendidus or Synchiropus picturatus (added after the tank is very mature), <<I think your tank is too small for these very specialized feeders, ever'¦and they are also likely to become 'anemone food'>> Six or Four Line Wrasse, <<Do be cautious here, these can become quite the little terror'¦ Definitely the 'last' to be added in the stocking order>> Anthias, Cardinals, Damsels, grazing Tangs (obviously I would not have all these fish, but choose from the list). <<Indeed'¦ But this tank is too small for a Tang as well>> Sabellid worms, Giant clams such as Tridacna squamosa, T. gigas, T. crocea, Hippopus hippopus. SPS corals, with careful placement to avoid interaction with the anemone. <<Mmmm'¦>> No softies to mess with the anemone, <<Wise>> of which there would be one. What do you think? <<Have stated my opinions [grin]. And I still think the SPS and a clam or two would make for a great display'¦>> **Well Barb, I think you and I have different ideas of what 'not many fish' constitutes for this tank. While this stock list is not excessive (depending on final numbers of Cardinals and Anthiines), it certainly isn't a 'light' load for this tank** I'm still learning! And, I'm teachable! << Very good, Grasshopper (imagine my best Chinese accent here). Do keep reading/researching your choices re environmental requirements, compatibility, et al'¦ And if/when necessary'¦you know where to find me>> **Ah good'¦let's do bandy back and forth before anything becomes 'permanent' ** Yes, definitely, lets! <<Cool>> **All 'pluses' here. You will also need a good quality skimmer, and some way to provide chemical filtration (canister filter or media reactor of some kind). And while we're talking chemical filtration'¦while 'researching/reading-up on' the other aspects of reef keeping, do a keyword search on our site and read-up on 'Allelopathy' ** I have an ASM G2 skimmer with a Sedra 5000 pump. How's that? <<Should do nicely>> I will read up on Allelopathy, which I believe has to do with chemical warfare between corals in tanks? <<Indeed, but more than just corals'¦ Algae, sponges, many types of organisms can/will employ chemical means of defense>> The chemical filtration will help with allelopathy, I presume? <<And more'¦>> **Hmm, I'm a fan of metal halide for most all marine systems'¦but this canopy sounds too limiting/would position the lights too close to the water I think. I think overheating will be an issue'¦and water splashes could easily 'do in' the bulbs or if present, constantly coat/obscure the shields (aside from outright failure, broken bulbs can also pose shock or fire hazards'¦and a broken bulb that is still burning can seriously damage livestock from excessive UV) ** The rests for the canopy could be lowered about 1-1/2in, would that make a difference? <<...? Wouldn't this just place the bulbs even closer to the surface of the water? Or perhaps I have misunderstood>> Or, I could call the LFS and see if they will let me return it for a store credit. <<This would be my first choice>> **Even so'¦I think you're best going with T5 lighting if you stick with this canopy** Okay. I think I may be inclined to return it or sell it so I can get the most effective lighting for the tank. **Ah yes, luckily winters are shorter and more temperate here in South Carolina** My son lives in NC on Topsail Island. His winters are nice, too! <<Likely a bit cooler this weekend!>> **The T5s are a viable option, though since you wish to keep clams and SPS (Acroporids I assume), I would go with 8 of the 39w lamps'¦six 10,000K and two Actinic** Okay, gotcha! **Too much wattage on the halides** That's what I figured when this was suggested! 'X'ed off the list. **This would be my first choice of any listed thus far'¦though I would be inclined to search out a different brand** Can you recommend any brands? <<Hmm, I generally 'build my own' from DIY components. I suggest you visit the reef forums (ReefCentral.com/Reefs.org) and query folks there re a quality fixture>> This configuration would be good, though, for the "new" biotope I outlined above? <<Yes>> ** Mmm, will still be measured in 'years' ** This is what I figured, and I am NOT considering it. **Agreed'¦and can cause more than heat issues, as explained** Yes, I understand. <<Ah good>> **Are we still talking about the LED fixture? ** No, the Current USA 2x150 fixture I mentioned above has 24 hour lighting... it was attractive to me for that reason. <<I see>> **Should be plenty'¦ The T5s can be mounted individually with individual reflectors'¦thus allowing you to use the full measure of the canopy lid** Okay, I will look into measurement information this evening. **Have done so [grin]** Yes, you have, Thank you! <<A pleasure>> **Feel free to write back for further clarification/discussion on any of these issues.

If there is room remaining I will order up two more. <<Okay>> How's the bulb choice? <<Too much 'blue' in my opinion Utilizing more bulbs with a lower Kelvin rating will give more output/provide more useful light spectrum'¦something I think you will find important to your SPS and most definitely to any anemone you try to place under this lighting>> I had a lengthy conversation with the lighting guy (reefgeek) and this is what he suggested I try for what I would like to keep. <<Apparently we disagree [grin]>> Thanks, again, Eric... We are currently getting about a foot of snow. Fun! Barb M. <<Always welcome, Barb. We to are supposed to see some 'white stuff' (about an inch), but temps are in the 40s so I have my doubts. Too bad'¦our cats have never seen/experienced snow! Regards, EricR>>

Re: Dancing with the Devil - New Tank and curing LR, and now, Reef stkg.  1/15/08 Hi Scott, Thanks for the advice. <Very welcome Ranjith.> Since there is a DSB, will it not digest the nitrates by the time the rock cures? <Theoretically it could over time with no other nitrate being produced. The reality is that it will not consume nitrates at the rate they will likely be produce curing rock. You will need some water changes, and should anyhow.> That is the main point of the DSB right? To control nitrates. <Yes.> I agree there will be a lot of nitrates but left alone, the DSB should digest all of it right? <Over time.> Also, what made you conclude that anaerobic activity was going on? <Hmm.. mentioned as a possibility. Actually unlikely at the depth we were talking about.> Any idea how I can keep the beach sand from flying around? <Only by controlling where and how your tank's flow is dispersed.> Will it help if I add slightly larger particle substrate around half inch above the sand? <This can help, but in an active reef tank the smaller particles will eventually resurface. Larger particles may also act as a detritus trap.> I plan to make this by using the mixer to grind some crushed coral. That should help in culturing larger pods as well right? <Somewhat, a refugium is better for this purpose.> Regarding the surge You think I should reduce the volume? <No, it sounds like a good plan.> I was thinking of an interval of 15-30 odd seconds between surges. Faster in the day and slower at night. <OK, will be fine.> I plan to keep the following critters. 1. Zooanthids and sea mats (around 10 varieties fragged to create the multi colour mix) <You may want to place these on rocks separated from the main aquascaping. Although they are quite nice, they can multiply very fast and become quite a nuisance.> 2. Mushrooms - (around 5-6 varieties fragged to create the multi colour mix) 3. Leather coral (mushroom leather, finger leather)- 2-3 pieces grown from frags. 4. elegance coral and hammer coral - one each <I urge you to skip the elegance, read the link below.> http://www.wetwebmedia.com/elegance.htm 5. sea pen (maybe) -- one <Difficult to keep.> 6. xenia 7. star polyps 8. Feather dusters (as many as possible :D) 9. Fromia Indica starfish - 2 10. Shrimps (4-6) <What kind?> 11. black serpent stars - 2 12. 1 giant clam <Careful with placement. Many species will need to be placed directly under your light.> 13. blue branching sponge <Again, any specific sponge? Some are much more suitable than others for aquaria.> Fishes: 1. Group of fairy wrasse (3-5) 2. Trio of multispined dwarf angel < Centropyge multispinus? Nice fish, but stick with only one. Too many territoriality issues here.> 3. Regal tang - 1 4. Long nose Hawkfish -- 1 <This fish may put some of your inverts in danger.> 5. Pair of Sebae clowns or skunk clowns <Go for tank bred Sebaes if possible.> 6. Bi-color blenny - 1 Can you suggest any butterfly that would leave the above mentioned corals alone along with the feather dusters? <One of the longnose butterflies should work, but will be pushing the tank's long term capacity in my opinion.> An anemone for the clowns would surely be out of the question right? <With all the mix above, I wouldn't.> Cheers again Ranjith < I hope this helps, Scott V.>

Chaetodontoplus septentrionalis in a captive reef? Gambling With Corals (Risking A Large Angelfish With Invertebrates)?  1/16/08 Hey guys and gals: <Scott F. your guy tonight!> Simple question. Is Chaetodontoplus septentrionalis an angel that can be placed in a captive reef aquarium (90G) without being too destructive? < I guess it's all relative..."Destructive" to some reef people is the loss of one polyp of coral. Yes- fishes in this genus will nip at all sorts of sessile invertebrates. It's rather uncommon in the U.S. trade, seeing how it has a rather limited distribution (mainly Southeast Asia and Japan). If you have a source and are up to keeping this beautiful fish, the risk may be worth it! My main concern is the size of the fish. This species can and will hit around 10 inches, and a 90 gallon aquarium is simply not large enough to house this species for anything close to a normal life span, IMO. You really will need an aquarium that is six feet or greater in length (preferably 8 feet), as they roam over large areas of reef in nature, and they do like caves and crevices to hide in.> I have a few LPS corals and a few softies (no SPS) and I'm willing to tempt fate on one of my favorite fish of all time if it could possibly be kept without tearing everything up. <A total dice roll, my friend!> If the fish is well-fed enough (3 times daily with New Life Spectrum pellets along with frozen foods -- all soaked in Selcon), could it be somewhat trusted not to be a holy terror to corals? I was thinking about keeping a clam, but I wouldn't trust a large angel with a clam since I've seen first hand one getting nibbled to death in the past and I'd much rather have a huge want of mine in the septentrionalis if at all possible. <Again- there is no guarantee. Even fishes with a "reputation" for NOT munching on corals can turn on them. Like people, fish are individuals, and we cannot expect them to conform to our behavioral expectations.> It's either that, or I was thinking of going with a Pomacanthus annularis which is my distant 2nd choice (but another gorgeous fish to say the least) which I've read in the FAQ's is one of the 3 large marine angels Bob would tempt fate with in a reef environment.- Jon <Well, Jon, I have seen the P. annularis in reef systems. Again, it's a gamble, but it's up to the hobbyist to decide his/her threshold. A more pressing concern is the HUGE size that this fish can attain (like 15 to 18 inches), and its need for correspondingly huge quarters! Keeping one of these fish in anything less than an aquarium of hundreds of gallons is cruel and unusual, in my opinion. My advice to you, my risk-taking friend: Try fishes better suited to the quarters that you can provide, such as a rare Centropyge species (try pricing a C. hotumatua or C. joculator if you want sexy and expensive!), which are just as challenging (and potentially destructive to reef invertebrates), but generally max out at 4 inches or less. Regardless of what route you take, there are tradeoffs that you must make, so be prepared and go for it based on what is best for you and your animals. Good luck! Regards, Scott F.> Jonathan Philpot

Is it the right combination, Reef, FO, no  -- 1/04/08 **Hi Crew, <Ash> First would like to thank the site a ton for all the information it contains, even a novice like me doesn't feel out of place. Have a 135 gal tank with 3.5-4 inch thick sand bed and about 200 lbs of live rock. SG is at 1.024, PH at 8.2-8.4, Calcium is kept at approx near 400. Bi-monthly addition of strontium, calcium and magnesium and Iron( all Kent marine) and once a month addition of Sera Marinvit plus. Am in the process of changing the fishes in the tank, which used to be orange lined trigger, <An Undulated I take it> one snapper (unknown) Clown surgeon, Maroon clown, Picasso Trigger, Fox face, Mata Tang , Sailfin tang (Indian). The new combination would be : Emperor Angel 4 inch Blue ring angel 4 inch <Mmm, these will likely NOT get along... and either one will grow too large for this setting> Picasso trigger 2.5 inch Lunar Wrasse 5 inch Powder Blue Surgeon 5 inch Foxface 3 inch Starfish (unknown ) <Do be careful here...> Two Carrot anemones <What species?> One tube anemone <A cerianthid? Not a good idea> Would like to know if the above combination is fine and if a maroon clown can be added? <I'd be reading re each species Compatibility, Systems... taking good notes. This mix won't work> Tank is over skimmed using two protein skimmers( Venturi and Saw Tooth) and the filtration is with bio balls and activated carbon and ammo rock mixed with zeolite. Have a nano reef also with one mandarin and three Pyjama Cardinals. Thanks in advance. <Welcome. Bob Fenner>

"The Conscientious Marine Aquarist" Comments and Questions. Reef stkg.  -- 1/04/08 Hello Mr. Fenner, I recently bought your book and thought you did a fantastic job giving out the information in an orderly fashion and also to go along with that, you did a fantastic job of explaining many subjects throughout the book in various details, which in turn for me made it much easier to understand. <Thank you for your kind, encouraging words. Do know that a new, 2d ed. of this work (CMA I take it) is due out in a few months. Are you familiar with our website?> I enjoyed reading your book and because you have established credibility I would like to ask you some questions about my tank at home and see what you feel can be done. Well here we go: Its a 65 gallon tank that is reef ready and has a 20 gallon sump underneath it with Live Rock and a protein skimmer. In the tank itself there is approximately 60-80 lbs of live rock along with about an inch and a half of fine substrate. <Mmm, you may want to increase, possibly decrease this level... Please read here: http://wetwebmedia.com/dsbdepth.htm> Metal Halide lighting. The tank has been running for about a year and a half now and I have a few questions on a last selection of fish to add. Inhabitants: 1 Bicolor Angel (4")2 Black Percula Clownfish (One is significantly dominant and has made itself the female, they also host an Long Tentacle Anemone.)1 Maroon Clownish (Hosts a Rose Bubble Tip Anemone which currently just split, so she lives in both) <This mix, Premnas could turn "ugly"... esp. with the other Clown species> 1 Green Mandarin (2")1 Sea Cucumber1 Cleaner Shrimp 2 Peppermint Shrimp1 Chocolate Chip Starfish Green Star Polyps Mushrooms Goniopora My question is... I'm looking for a last introduction of fish to my tank and what I want is a mated pair of fish that can fit in a 65 gallon tank and live happily with the residents that are currently in it. I want to get two of the same fish and have them pair over time or possibly buy a mated pair of a certain kind of fish. What fish for this tank would you recommend to me? Thank you for your time and cooperation, it is greatly appreciated. Sincerely, Aaron <Mmm, perhaps a pair of Cardinals (Apogonids)... Please see WetWebMedia.com re this family, many other choices... Bob Fenner>

Stocking/Compatibility... Reef  1/2/08 I am working on building a stocking list for my new tank. It is about 330gallon and 75 gallon sump. <Wowsie.> Let me know if you believe this stocking list for a reef tank is:  overstocked, low, medium, or heavy load. If you believe this is overstocked, your recommendations for removal would  be appreciated. 1 x Purple Tang <If you go with a Powder Blue, there will be territorial issues here.> 1 x Coral Beauty Angelfish 1 x Blue Devil Damsel <Would not add this hellraiser.> 2 x True Percula Clowns 1 x Yellow Striped Maroon Clown <A semi aggressive fish, with caution> 2 x Lyretail Male Anthias <Would only use one male, will work out much better as there is generally only one male in a harem of Anthias.> 6 x Lyretail Female Anthias 8 x Green Chromis 1 x Powder Blue Tang <Do read here on this fish. http://www.wetwebmedia.com/powdbluetg.htm> 1 x Sailfin Tang <Same as the Purple Tang, the Powder will be aggressive toward them. And, if the Purple Tang should be your choice, eliminate the Sailfin as the Purple Tangs are the most aggressive in the Zebrasoma genus and you may have territorial issues here also. Given the size of your tank, you may be able to pull this off providing plenty of rock is used for retreats.> 2 x Yellow Tail Wrasse (Anampses meleagrides) <These wrasses are difficult to acclimate/keep. I'd go with one or two Flasher Wrasses. I'd eliminate the Blue Devil, Maroon Clown, and two of the tangs. This will give you a very nice display with little or no compatibility issues, and depending on the efficiency of your filtration system, your stocking level should be fine. As for wrasses, do use a sand bottom, not crushed coral etc. Wrasses do much better with a sandy substrate as they do burrow in the sand if danger threatens and also for the night.> Thanks! <You're welcome. James (Salty Dog)> Bryan Re: Stocking/Compatibility 1/3/08 Thanks for the info! <You're welcome.> I forgot some important information, I already own (coincidently the ones you recommend I ax). Purple Tang in 46g <Definitely time for larger quarters.> Maroon Clown in 26g Blue Devil Damsel in 46g clowns in 26g Coral Beauty Angel in 46g I would like to keep most of them as <if> possible as I have had all of them for over 2 years. <Great> My tang and my Maroon Clown both seem to be fairly docile fish, perhaps because of the feeding or perhaps because they are still not nearly full grown. <Being fed well does help reduce aggression.> So if I kept the purple you'd recommend I maybe try the Powder Blue given I have 330 pounds of rock and plenty of hiding spaces? <No, I said if you got the Sailfin Tang you may be able to pull it off in a tank your size. The Powder Blue once acclimated can/will become very aggressive toward other tangs, and you may have problems with the Purple and Sailfin Tang, all depends on the personality of the individual fish.> ....however Sailfin is asking for trouble as I understand it. <Possibly.> As for the wrasse, I have 4-6" of sugar sized aragonite sand and would really like to try the yellow tail, perhaps I will start with one. I have controllers and automation built-in to keep water quality pristine with daily partial water changes, an oversized re-circulating skimmer, and a refugium that will at some point be stocked with macro-algae. I am leaning towards Ulva sp because I am concerned Caulerpa will enter the main display with nobody to eat it. <Understand, and in future queries please cap the names of fish. Saves me time if I do not have to edit the query before posting. James (Salty Dog)> Thanks!!! Best Bryan

Stocking question, SW Reef  -- 1/2/08 I have a 3 month old 75 gallon tank with 100lbs LV. I have a 24" hang on refugium with macro algae and a Remora Pro skimmer. Please let me know what you think of the following stocking plan: 1 - Coral Beauty Angelfish (waiting until the tank is 6 months old) 5 - Blue Green Chromis 2 - Common Clownfish 1 - Orchid Dottyback 1 - Six line Wrasse 1- Lawnmower Blenny 1 - Scarlet Hawkfish I also plan to have several soft corals. Please let me know what you think. Thanks so much I love your website. <A very nice list... should work out fine. Bob Fenner>

Over crowding, 55 gal., SW, reading  -- 1/2/08 Hello there and I would like to thank you in advance for your replies. I am starting my reef tank and I am wanting to know if you think that what I am wanting to do is ok. Alright well the tank is 55 gallons and the equipment is a All-Flow freedom filter with built in protein skimmer the light is a Corallife Deluxe Lunar Series it has 2-65 watt true actinic 03 blue compact fluorescent and 2-65 watt 10,000K daylight compact fluorescent lights and the four 3/4 watt lunar lamps. I have about 80lbs live rock and 80lbs live sand. I currently have 4 fish they a two percula clowns a flasher wrasse and a neon goby. The clean up crew so far is 3 sand sifting star fish one cleaner shrimp ten margarita snails one large turbo snail. I have a closed brain, open brain, button polyps, Alveopora, candy cane, fox, and a xenia. Everything is looking great! All water is testing great with nitrates at 0-5 ammonia is 0 ph is 8.2. Now for the question and I hope that I can do this I want to add the flowing fish 1 yellow tang, 2 black and white clowns 1 mandarin goby 1 six line wrasse. The clean up that I want to add is Nassarius snails another cleaner shrimp 2 fire shrimp black long spine urchin brittle star emerald crabs flame scallops <Nah> and a few turbo snails. Some coral that I would like to add are a neon green anchor a clove or pipe organ a torch a frogspawn a toadstool a bubble coral a plate and a slipper or tongue. <...> I know that this is a lot of creatures and of course a slow process that will take a while to get everything (if I can). The plan is to go slow and WATCH WATER READINGS. Sorry this is so long but I don't want to bother you will a bunch of e-mails so I thought that I would write you one long one. Thanks again Brandon <Please read on WWM re the Systems, Compatibility of all you list... Take good notes. Bob Fenner>

Decomposing Starfish... What is: Things I wouldn't keep in my reef tank... 12/31/2007 <Greetings! Mich here, apologizing for the very long delay.> I seem to have a problem with decomposing starfish. <Unfortunately, not an uncommon problem.> I have a 72-gallon tank that has been set up for about 9 months. It has cycled very well, and has wonderful coralline algae growth. I have maybe about 20 pounds of live rock, <I would consider adding more.> along with a Firefish goby, coral beauty angel, blue damsel, royal Gramma Basslet, and tomato clown. As far as non-fish goes, I have a tomato anemone, <Tomato Anemone?> trumpet coral, a pulsing xenia coral, and an orange sponge. <I personally would not keep the sponge... I have had such sponges up and die and take many tankmates along for the ride...> I had a chocolate chip star in the tank for about 6 months, then about 2 weeks ago I noticed that it had a few white spots on its top. I immediately feared the worst and put it in my 10-gallon hospital tank. <Hope you also use it to QT as well! Some reasons to here: http://www.wetwebmedia.com/QuarMarFishes.htm http://www.wetwebmedia.com/quarinverts.htm http://www.wetwebmedia.com/ca/volume_3/cav3i4/quarantine/Quarantine.htm http://www.wetwebmedia.com/quaranti.htm > By the next day, all 5 legs were decomposing with large white chunks falling off, <Nasty!> yet the poor thing was still alive, and by the next morning it was dead. <I'm sorry for your loss.> I looked at my fish very carefully and none of them showed any signs of anything, so I figured that perhaps the starfish got a small cut and got infected, as starfish tend to do. <A possibility.> I left my tank alone for about a week and a half and continued to keep an eye on my fish. They still showed no signs of any sort of disease, <Good.> so 3 days ago I bought a blue Palau starfish. The first day was fine, the second day it looked a little cloudy so I immediately separated it. This morning I found it dead and halfway decomposed, all of the blue flaking off. I'm at a complete loss of anything that would cause this. Please help! <Most starfish brought into the aquarium industry are doomed. They are very sensitive to osmotic changes, such as variations in salinity, and often die from osmotic shock. Starfish generally don't do well in captivity as the diets of most species are poorly understood, if known at all. I would highly discourage from purchasing any more starfish... IMO A red brittle star (Ophioderma squamosissimum) would be a similar but much better choice. Red brittle stars generally fair well in captivity, are good scavengers and unlike the green brittle star (Ophiarachna incrassata), are not predatory on fish. Cheers! Mich>

More fish? Adding To The Mix (Stocking Question) 12/30/07 Dear WetWebMedia crew <Hey there! Scott F. at your service!> I have a 80 Gallon reef tank. I would like to know how many fish I could safely add to it. At the moment I have: A Yellow surgeon A Centropyge Argi Two Firefish (Decora) A Clownish (Ocellaris) A Gobiodon okinawae A Lawn Mower Blenny And a Royal Gramma I Plan to add a Fridmani (Tank- Bred) Unfortunately, it is not often available in Denmark where I live, but since it is one of my favourite fish I'll wait for it. <Admirable! I'm the same way...I'll wait MONTHS for the fish I want. Of course, I'm not that patient with other stuff ("I must have a candy bar NOW!"), but with fish, it's worth the wait!> In addition to the fish, I have 8 shrimps(3 Blood shrimps, 3 Lysmata amboinensis 1 Dancing Shrimp and L. wurdemanni) I also have a Blue Linckia and a Fromia, 3 hermit crabs (Blue legged) and various snails. <Nice mix!> Is it possible to add more fish? I was thinking of 3 Green Chromis, but since I value your opinion, I would hear your thoughts first. Thanks for a wonderful site. Happy new year! P.S. I have 80 Pounds of live rock. Michael Fick Dragør Denmark <Well, Michael, I believe that you could add 2 or 3 smaller fishes, if you are careful with acclimation and compatibility. The Chromis might work out okay, actually. I have never really liked Chromis, myself, but they are attractive and interesting. In addition, they will inhabit a niche that the other fishes will not spend as much time in (the upper water strata), so this will make the tank a bit more "complete" at all levels. Best of luck! Regards, Scott F.>

Stocking Levels 12/29/07 LOVE website; perhaps greatest widespread enhancement of informed & conscientious stewardship of marine life developed. Wish its use by me commenced prior to starting hobby. So many metrics for biocapacity load given infinite variations of constituent organisms in any given system (& shortcomings of simply measuring 'inches' as often cited given material differences in volume & bioloads); often can't reconcile. So, quick question: is my tank 'overloaded'? If not, would like to add: Pearl Jawfish, Helfrichi Firefish, Hippo Tang (3-4" - such that per General guidelines of growth in captivity found, ~6" 3-4 yrs hence, at which time larger accommodations may anyway be requisite for angel currently kept) - OK? 90g FOWLR. ~8 months. In-sump protein skimmer & wet/dry (likely to be replaced w/LR refugium at later date per recommendations). [Mushrooms & coral polyps to be tried (depending on appetites of butterfly & angels)]. Current friends: Chrysurus Angel (3-4") <<Needs a larger system. RMF>> Lemonpeel Angel (3-4") Pakistan Butterfly (4-5") b/w Ocellaris Clown (2.5") Royal Gramma (2.5") McCoskeri Flasher Wrasse ("2.5") Geometric Pygmy Hawkfish ("2") 2 Catalina Gobies (2.5") <<Coldwater animals. RMF>> 1 Red Headed Goby ("1.5") Scarlet Skunk Cleaner Shrimp Emerald Mithrax Crab <Mike, your bioload is too high now, I'd forget adding any more fish.> Many thanks, <You're welcome.

Centropyge loricula'¦ Reef Acceptable? (Oh Yes!) -- 12/27/07 Hey there, <<Justin>> After Christmas I was looking to use some of my cash for some aquarium additions. <<A popular notion>> As I was shopping around the LFS a flame angel caught my eye. <<One of my faves'¦>> I have seen them before, but I have a reef setup and the possibility of "nipping" has always scared me off. <<Is a possibility'¦though worth the 'risk,' in my opinion>> I have been reading about them and continue to see both sides of the story. <<Indeed>> So I was looking for a "personal" answer. My tank is a 75 gallon reef (softies and LPS) with about 90 lbs of live rock under two 250 watt MH. I have a 55 gallon refugium (sand, rock, and macro algae) running on the tank as well. I plan on including a few more corals and some clams. If my main concern is for the destruction of my current livestock or the hindrance of future invert additions, what are the chances that the purchase of a flame angel (which I would make the last of the fish additions due to possible aggressions) would cause me more grief than joy? The flame angel is so beautiful and would really add to my tank. Is this beauty worth the risk? I know that all fish are unique and you are not a fortune teller, but I guess I am looking for advice from some people with more experience observing these fish in similar settings over time. Thanks, Justin <<Well Justin'¦I can tell you that I have 'personally' kept this fish in 'reef settings' of differing types for the past couple decades, and not once have I had an issue with 'nipping.' Maybe I've been lucky'¦but I also think there are a few things the hobbyist can do to lessen this behavior. One is to purchase juvenile fish that may not be quite 'set' in their eating habits yet'¦ Another is to not 'starve' your fishes'¦ Keeping all well fed will go along way towards keeping them from picking at your inverts. Also, do provide for the 'psychological' as well as their physiological health. Overcrowded, bullied, or overly exposed (no proper cover), etc., fishes can often exhibit 'behavior' abnormalities as a result. Centropyge loricula is a stunning and hardy aquarium addition, and in my opinion, is healthiest/best showcased in a 'reef' setting. Like you mention, each fish is an individual'¦but I definitely think this species is worth a gamble. Good luck! EricR>> <Well-stated. RMF>
Re: Centropyge loricula'¦Reef Acceptable? (Oh Yes!) -- 12/27/07 Eric, <<Justin>> Thank you for the quick and helpful response! <<Quite welcome>> I would like to follow up by asking another question in regards to the overcrowding and/or bullying that may cause abnormal behaviors. <<Mmm, okay'¦but is pretty straightforward>> I currently have one yellow tang and two blue-green Chromis in my tank. However, I had planned on adding 5-7 more Chromis and two black Ocellaris clowns to the tank before considering the flame angel. <<I see>> Would my current livestock or the future of it be a problem with overcrowding and/or bullying? <<These fishes/this order should all be fine with the angel. I do have some small concern re the group of Chromis in this size tank (75g)'¦in my experience, they're not nearly so docile toward conspecifics as many seem to think>> Thanks again, Justin <<Always welcome. EricR>>

Fish and stocking recommendations 12/25/07 Hello, I was wondering if you could give recommendations for a new saltwater set up. I have experience with freshwater species (15 years), however basically new to saltwater. I have a 72 gallon bow with 20 gallon sump. I have done a great deal of research (Bob's book for xmas) and should have all necessary equipment to have a successful tank. The tank is currently cycling with 55 lbs live rock and Aragralive sand. I intend on eventually keeping one or two clowns with host anemone (also like flame angel). I understand the water quality and maintenance that will go along with the anemones, however, would like to keep hardy and peaceful species. I'm just not too sure on stocking levels and time tested tankmates. Any suggestions would really help point in the right direction. thank you for your insight, mike <Mmm... what you list can work... and there are MANY other compatible choices... I encourage your perusing WWM re these, and as many visits to your LFS as time allows... take your time... this is not a destination, but more a journey to be enjoyed, savored. Bob Fenner>

Review this list of fish/inverts, please?  12/24/07 Hi, I have had a 55gal aquarium for a little over a year now. It has had very few fish in it, just a damsel, a smallish yellow tang (a gift from a friend), and a camel shrimp. I gave the damsel away (a Fiji yellow belly) to make room for more peaceful stuff. I recently got a big load of awesome live rock (with lots of button polyps and neat-o stuff on it), so I'm up to about 50lbs total. I'm wondering if you could review this small list of stuff I'd like to have and give me a thumbs-up or thumbs-down. If thumbs-down, maybe make some recommendations, if you have time. <Hotay> Yellow Tang (already have) (This species might be too big for my 55gal, but he's extremely healthy and beautiful so far. If he gets too big in a few years, I might have to give him up. What do you think?) <Think you're fine here> Camel Shrimp (already have) Ocellaris Clown and bubble anemone (will have ~5W/gal CF lighting). <Do read re Entacmaea culture on WWM> Flame Angel Algae Blenny (I'm pretty good at growing algae, so far...) one or two Banggai Cardinals (maybe pajama cardinals?) (What's the proper quantity of these to have? One? Two? Three?) <See WWM re> fighting conch some other small snails some hermit crabs (blue legs?) 1 sally lightfoot crab? (Is this one safe?) 1 brittle star 1 sea urchin <Mmm, I'd skip on the Crab... the Centropyge might/not go... psychologically... but you'd likely see its decline in time to remove it...> I'm least sure of the inverts. I'm not sure which will each which others... Thanks a million. Seth <Really... mainly the crab. Cheers, Bob Fenner>

Upgrading Tank/Compatibility 12/19/07 Hi Guys: <And gals> First off I'd like to say how valuable your site is for information. I've come here in search of answers to question on more occasions than I can count and have always been super happy with the information I've found. <Good to hear.> I am currently running a 77 gallon SW reef tank, and the existing fish population is: 2 Clarkii Clowns (with five Bubble Tipped Anemones {actually 2, one split into five}), 1 Yellowtail Blue Damsel, 1 Bicolour Angel, 1 Decorated Goby (thought he was something else when I bought him, but he turned out to be a very happy accident, awesome fish), 1 Mandarin Dragonet, <This guy must have nine lives with all the anemones in there.> 1 medium sized Yellow Tang, 2 Cleaner Shrimp, and a Flame Lobster. <I'm guessing Enoplometopus occidentalis (Hawaiian Reef Lobster).> Everything has been very happy and healthy and living very harmoniously together since April. I am currently in the middle of an upgrade to a 130 gallon tank for all my little treasures and am trying to plan for the future population of the larger tank. Actually the 130 gallon is going to live beside a 65 tall and both tanks will be sumped together <How do you plan on pulling this off?> with a 30 gallon sump so the overall volume will be over 200 gallons. The 130 will house all the current residents of the 77 gallon and the 65 gallon will house 2 Tomato Clowns, a Neon Goby, a Mandarin Dragonet, and possibly a Flame Angel. <Mmm, may/will have problems here. As the Tomato Clowns grow they do become rough housers, do not know how well the goby and dragonet will fair in this setting.> I would like to add a Powder Blue Tang <Do read here before considering this addition. http://www.wetwebmedia.com/powdbluetg.htm> and a couple Neon Gobies to the 130 when it is time to finally move everything over. My question is, can I house a Yellow Tang and Powder Blue Tang together in a system this size or is it too small? Will there be a lot of aggression between the two fish, <If you are lucky enough to acclimate the Powder Blue, he will become very dominant and aggressive toward any other tangs in the tank.> and if so would I be better off to add a third tang (like a hippo maybe) to disperse the aggressive behavior? <Is best to have the Powder Blue as the only tang in the tank.> I've seen lots of instances where people are keeping four or five different kinds of tangs in similarly sized systems with no problems, but don't want to just assume this will all work itself out and toss a bunch of fish together, cross my fingers, and see what happens. <You can get away with it in larger systems, but a 130 is too small to pull this off.> Also, the information I've found about the Flame Lobster is that he is reef safe and will not harm my fish, but I'm also aware that lobsters are ambush predators and wonder if the neon gobies I hope to add would be safe in this community. <Small fish such as the Dragonet and Neon Goby will always be at risk, larger fish should be fine. Right now I'd be more concerned with all the anemones in your tank. Anemones and Clownfish are best kept in dedicated systems.> Thanks so much for all your help <You're welcome.

Potential Tank Inhabitants, Reef   12/18/07 Thanks for you help as always! <Welcome> I'm trying to figure out if the inhabitants I would like to add to my tank would push it past its bioload capacity. TANK DESCRIPTION: 180 gallon reef tank 40 gallon sump (about 25 gallons of water in it) with refugium ~160lbs of fully cured live rock... combined from several other smaller, very well established tanks Sequence Reeflow Barracuda (4500gph) Euro Reef RS-180 skimmer Corallife Calcium reactor Corallife Aqualight Pro (48" model with 2, 250W Metal Halides) Corallife Aqualight Pro (72" model with 3, 150W Metal Halides) (yes, that's two light fixtures on one tank) Water quality is almost ideal across the board CURRENT INHABITANTS... FISH: 1 Yellow Tang (~3.5" in length) 1 Six Line Wrasse (~2" in length) 1 Lawnmower Blenny (~4" in length) CNIDARIA: 1 Pagoda Cup Coral (~5" in diameter) 2 Finger Leathers (one is about the size of two golf balls, the other about the size of two softballs) 12 (or so) Green mushrooms a cluster of Proto Palythoa Zoanthids a cluster of purple Zoanthids OTHER: 1 Tridacna Crocea (~4") 1 Tridacna derasa (~4") 2 sand-sifter starfish 1 Cleaner Shrimp (~2") 5 Turbo Snails (big-ish ones) 1 pesky urchin that I can't seem to get rid of... but will (hitch hiker) Plenty of Aiptasia (...to get rid of) Here's what I'd like to add... FISH: 2 small Scribbled Rabbitfish (Siganus doliatus) (I had excellent luck with a S. virgatus. He and my tang got along swimmingly (sorry for the pun)) 5 or 7 *small* Green Chromis (C. viridis) I hear they do better in odd numbers. 2 Diamond Watchman Gobies (V. puellaris) OTHER: 5 Peppermint Shrimp (to control the Aiptasia, hopefully) 12 more Turbo Snails Does that sound like too much? I don't want to stress them out. Any advice on additions or subtractions would be much appreciated. Thanks for taking a look, Eric <Can be done, and reads as a very nice arrangement. Cheers, Bob Fenner>
