Peppermint shrimp, anemone and Dottyback compatibility   10/2/06
  Hello, back for my weekly question.  Hope you are doing well.  I am sure there is a answer to my question somewhere on WWM, but I am having trouble finding it.  On my endless quest for a cure of Aiptasia, I am thinking of purchasing 4 or 5 peppermint shrimp.  My question is, will the peppermint shrimp go after my bubble tip (huge) or any of the LPS corals I have (yes, bad mix I know)?  
<Likely so>
Lastly in your opinion would my blue flavivertex Pseudochromis go after my peppermint shrimp?  
<Maybe if/during molting if there is insufficient cover>
If either of these answers are yes, I can put the peppermint shrimp in my sump with some Aiptasia covered rocks, right?  Thanks, Ryan.
<Yes. Bob Fenner>

Lyretail/Steene's Dottyback comp.   9/4/06
I have a 35gallon tank w/ a female Pseudochromis steenei  or also known as the Lyretail Dottyback.
<Yikes... a gorgeous, but very aggressive species!>
  Her name is Morticia :)
<Good name here>
  anyhow., I'm going to be upgrading to a larger tank - maybe a 100gal (not sure yet). What I'm wanting to know is: 1) What will cohabitate with my Dottyback?  [right now I only have a black sea urchin & chocolate chip starfish sharing the tank w/ no problems] 2) If there is any other fish that can cohabitate what size tank should I get?
<"The bigger the better">
3) And what procedures should I follow to make a safe change?
<Stock Morticia last...>
THANK YOU! It's such a rare fish there's hardly any reading material other then what a terror the fish is. I love it...it's the first fish I can hand feed. NO FEAR for a little poot. :) 
I couldn't find the Dottyback FAQ's again after I got redirected to register.  Sorry, I hope you don't mind me emailing my question directly.

<Mmm, we send all direct as well as posting. Whatever you settle on, make sure it's at least as large, fast, smart... and place it/them first. Bob Fenner>

Re: Lyretail Dottyback  - 09/14/06
I got the male Lyretail in the mail yesterday and it is only 1/2 the size of Morticia.
<Trouble>
I never guessed the male would be a juvi., but I'm thinking this could be to my advantage if I can handle this right.  The Plexi glass separator is working keeping Morticia on her side but Gomez (will be his name of course) is able to venture to the other side.  It's totally incredible because it appears Gomez actually knows which side is his, only after 3 or 4 hours in the tank.
<Oh yes...>
I thought it was kind of funny in a sense because when he found an opening to the other side Morticia let him know she was there and he started high tailing it back to his side.   She just snapped at him and then she went back into the rocks.  It wasn't like she chased him around or anything, but it did startle him enough to start looking for his escape passage back to home turf.  My questions are now.,
1) since he is the smaller of the 2 can I safely remove the separator.
<No... not likely>
[I thought the male arriving would of been larger and would of possibly harmed the female,,, not the other way around] or 2) do I need to wait until he's an adult size also before putting them together?
<Can try... with you being present only... to re-separate them>
  and still wait until I get the larger tank? [they are housed in a 37 gallons right now with no other fishies]  
3) How long does it take to reach maturity?
<Mmm, likely another six months or so. Bob Fenner>

Re: Lyretail Dottyback  9/15/06
I was concerned but not any more because nature is dictating my next step.
<As it will>
I guess even in fishy land boys will be boys and girls will be girls. It's been three days now and Gomez's boy curiosity and persistence has kept him on Morticia's side of the tank most of today. And Morticia well it appears has fallen for his dashing good looks & charm because she is not chasing him away anymore, and has even found a back door to Gomez's side of the reef.
Hell, and I thought this was going to be a long and drawn out process! A few hours ago I removed the Plexiglas and all is well, actually better then well.  It's obvious Morticia likes the extra room to move around. I don't see anything to be worried about anymore  <big grins>
<We'll see...>
I just saw MACNA XVIII is being held in Houston.
<Ah, yes>
  I only live 30 miles North of the city so you bet I'll be there.
<Good>
I saw a banner showing y'all will be there also.  Will y'all be displaying or selling anything?
<Mmm, I'm giving a pitch late Sunday>
I can't wait.
Has it ever been held in Houston before?
<Don't recall it ever being there>
Thanks for all your assistance.  If by chance we have any little Addams I'll let you know.  I've been kind of documenting my process in the forum something I still need to update since my last step.

Goby Addition/Pseudochromis Aggression - 08/31/06
Hi WWM Crew,
<<Good Morning>>
I have a 30 gallon tank all water parameters are very good.  In the 30 gallon tank is an Ocellaris Clownfish (Amphiprion ocellaris) and a Fridmani Pseudochromis (Pseudochromis fridmani).  I was wondering if I could move a Yellow Clown Goby (Gobiodon okinawae) which I have in another tank into the 30 gallon tank?
<<Yes>>
Even with the Fridmani Pseudochromis already in there because they tend to be aggressive fish.
<<If "tank bred/raised" it will be much more "mild mannered" than its wild caught brethren.  But either way, I think the goby will be fine>>
Thanks for your reply.
<<Quite welcome.  EricR>>

Mithraculus comp. with Dottyback   8/6/06
I put an emerald crab in a 55 gallon tank with live rock, sand. The emerald crab was killed and/or eaten by the only fish I have in the tank; a strawberry pseudo. I was using him to rid the tank of excess bubble algae. It is the first time I have ever kept one of these fish, and found nothing to indicate the emerald crab would be in danger. Is this normal behaviour for this species? (strawberry pseudo) Thanks, Eddie

911--Dottyback eating hermit crab   7/7/06
Hello!  Thank you for this amazing website.  I have learned more than a lifetime of experience from you and I love Anthony's and Bob's books.  I have kind of an emergency because my Strawberry Dottyback just ate my reef hermit crab--tail first--and the claws, etc. seem to be stuck in his mouth!
What should I do?  Remove the crab?  I can send a picture if you would like.  Thank you!  Jessica
<Mmm, I would try to extricate the crab exoskeleton bits here... two nets to catch the Dotty, gentle pulling with tweezers/forceps... Good hunting! Bob Fenner>

Eel Blenny/Pseudochromid Question... with Dwarf Lions OK, with a Queen Trigger, No Way   6/17/06
Hello,
I have recently come across a Eel Blenny/Green Wolf Eel (Congrogadus subduscens) at the local fish store, but have been having some
difficulty in finding info on it.  I've read that it gets fairly long in length, but despite its size is quite passive as a Dottyback.  Can you please reconfirm this?
<Please see here: http://www.wetwebmedia.com/pseudoch.htm>
How passive is it?  
<Quite... maybe a 2-3 out of ten...>
In my tank I have two dwarf lionfish (at the moment, inedible size).  Would these fish go alright together in the future?
<Should, yes>
  I also have a decent sized queen trigger.  Any problems there?
<!Huge... Balistes vetula is close to a "ten out of ten"... Not to be trusted with these other fish species. Bob Fenner>
sincerely,
Aaron Raney

Dottybacks/Compatibility   5/25/06
Hello again and thanks for responding to my last e-mail!  The page  that I was directed to was very helpful.  Thing is, I wasn't sure when it  was written.
By that I mean, was it written before orchid dottys were  being tank raised and being considered more "passive" for lack of better words,  or was it referring to the wild orchid dottys, which I heard can be living  terrors.  <<Was written (my me) ahead of this time. RMF>> I'm just not sure whether to take the gamble on these guys or  not.  I don't want to take my tank apart to catch these super quick and  agile swimmers if they get out of hand.  I know they may become more  aggressive as they get older, just wondering if that is still true for tank  raised orchid dottys.  Sorry for the trouble, and thanks  again!
<Tank raised Dottybacks that I feel would be compatible/safe are:
Pseudochromis Fridmani/Fridman's Dottyback
Pseudochromis Springeri/Springer's Dottyback
Pseudochromis Flavivertex/Sunrise Dottyback
Pseudochromis Bicolor/Bicolor Dottyback
All of the above may chase smaller fish but generally have good personalities.
They will defend their nook from intruders, all will prey on bristleworms, and most important, if more than one is desired, they should be put in the tank at the same time.  I have a Bicolor Dottyback in a 30 mini reef that is a perfect gentleman.  All are easy to care for.  I hope this helps you out.

Dottybacks/Compatibility  - 05/22/2006
Hello WWM crew!
<Hello>
I have read your FAQ's like crazy trying to establish an opinion on  tank raised Dottybacks and their temperament...I still need help!  I read  that Orchids are some of the more passive species (among tank raised  Dottybacks).  Have they possibly become very passive in the latter stages  of the tank bred process?  I have a 95 gallon reef tank with currently  100lbs of rock, I am adding more slowly since that stuff can be pricey around  here.  It currently houses 1 ocellaris clownfish, two pajama  Cardinalfish, one peppermint shrimp, and
one skunk cleaner shrimp...yep, that's  all, it's a reef in progress, and I take it slow!  
<Ahh, patience, an excellent tool in this hobby.>
I am trying to choose the tankmates, and am reading like crazy trying to make sure I don't get a fish that I have to disassemble my tank just to catch him cause he is pounding another fish.  Basically, I would love to add an Orchid, or possibly the hybrid Indigo Dottyback, but don't want to do so if he  is going to pick on other fish.  I would like to place a yellow assessor in there as well, but would rather have the Orchid or Indigo.  Are these tank  raised species likely to pick on my shrimp or bully any other fish, and if they would bully some tankmates, which ones should I avoid?  The cardinals are  kinda slow and peaceful, I would really hope that a Dottyback will not bully  them as well.  The LFS owner said in his opinion they have become as docile  as any fish, and he would label them as "peaceful, but territorial." He didn't  think
they would seek out someone to pick on just for sport, what's your take on this?  I appreciate your help, and value your opinions and knowledge, it  has been very helpful in the past!  Take care!

Mauled Dottyback - 26/4/06
Hi everybody!
<Hi Sam!>
This is Sam from India
<You've got John from China today.>
Today morning when I was checking out my tank all fishes were fine.
But my favorite fish the Diadema Dottyback was not so well, it looked like it could not swim and is struggling to change its place.
So I took my probe stick, as usually it should move when the stick is taken near it.
But it did not move much but was struggling to move, there is some problem I thought!
Then I moved it with my stick and to my horror its entire stomach was eaten away!
As it was struggling too much, I thought there is no chance of recovery so I just put it in the freezer and had to euthanize it.
Was this right?
<Oh! That sounds horrible! I think you made the correct decision to euthanize the fish and spare it from its slow demise. However, opinion varies on whether freezing is the most humane method. clove oil anesthetization - or even a whack on the head - are likely quicker and less painful for the fish. But this is a moot point - you should be proud that you did the best you could.>
What could have caused it? In my tank I have a Yellow-tail Damsel, a Blue Devil, a pair of Allardi Clownfish, and a few Nerite snails.
The Dottyback was the oldest dude, and no one messed with it!
<unless it was very sick/weak already, I don't know what could have happened here.>
The tank is full of live rock; could some thing be hidden in it?
<Could have: have you added any live rock recently? Loud clicking/tapping noises at night would be a tell-tale sign of a mantis shrimp.>
And the best part is that it was not dead and then eaten, but was alive when eaten!
<Poor fish.>
No other fish was interested in checking him out! It just happened 10 minutes ago, so still a bit sad.
<Understandable. Do keep an eye out for unwanted hitchhikers if you have recently added live rock. Other things to think about are sharp objects - or perhaps falling rocks - in the tank. Maybe an exposed powerhead impeller? Or, if the fish fell ill beforehand, then look into water parameters.>
Anyways, see if u can answer this!
Thanks,
Sam
<I hope you get to the bottom of it! Best regards, John.>

Trapping a fish in a fish trap ... bad Dottyback   4/23/06
Hi guys, I wrote to you earlier about a yellow Pseudochromis that was in my quarantine tank. You said it would be ok to introduce into my 125g reef. Well, he has eaten my fire shrimp, peppermint shrimp and possibly my emerald crab. He is extremely territorial.
<What species is this Dottyback? Some are pure terrors (e.g. Steene's), while others are by and large "reef safe" (the tank produced Fridman's for instance>
Unfortunately the entire tank is his territory!! My two remaining shrimp ( skunk cleaners) are resorted to living on powerhead. If  they go to the sand then he bullies them. My question is on using a fish trap for him. How do you use it. I have a full blown reef, with rock and corals so the typical fish net won't work here. Please advise me how. Thank you, Stephanie

Pseudochromis aureus compatibility with shrimp  3/18/06
Hello all, I am in a dilemma. I purchased from an on line retailer a yellow Pseudochromis fish, about 2" which has been in  quarantine for 30 days. My fear, and question, is that I have read (of course, after purchase) that they can eat ornamental shrimp.
<Some Dottybacks have a predisposition to...>
I have a 125g. tank with plenty of rockwork and corals. Once I put this fish in, it will be a nightmare to catch if it is indeed a shrimp killer. What do you think is the likely hood of this happening?
<With this species, sized specimen, type of set-up... very small chance>
I have 4 shrimp---1 fire shrimp 2", 1 peppermint shrimp 2", and 2 cleaner (skunk) shrimp 3". I intend to keep him there until I am fairly sure he is ok. You all have been right on in the past. He seems so shy in the quarantine tank, but putting him in the big tank may open up other problems, so I want to be prepared. Thanks in advance, Stephanie.
<I would risk this introduction/mix. Cheers, Bob Fenner>

Royal Gramma Help... actually, an example of punctuated knowledge, learning in our species... A useful paradigm for military conflicts, government manipulation of the masses   3/16/06
Hi, I started a fish only saltwater aquarium about 7 weeks ago. I cycled the tank with damsels and removed them as I was told by my fish consultant when I was ready to get other fish.
<Mmm, see WWM re this practice... the damsels may have left you a nasty (disease) surprise...>
I bought 2 percula clowns and 1 royal Gramma. In about 2 days, one clown died and from the way I described it, my fish consultant believes it was clownfish disease.
<There's more than one... Brooklynellosis? Should not have occurred if these were tank bred...>
About a week later, I lost the other one. I am waiting about 2 weeks before I buy anymore clowns.
<... in the meanwhile, please read on WWM re these animals needs>
I have now had the royal Gramma for about 3 weeks and over that time I have added a Heniochus butterfly, a coral beauty angel, and a strawberry Pseudochromis.
<... how large is this system? How filtered?>
The Pseudochromis charged at the royal Gramma once or twice when I first added him to the display tank, and they have seemed fine ever since.
<Will be unless this system is "at least four feet long">
I see no tension between any of the fish right now. They are all eating fine and look healthy, except the royal Gramma. A couple days ago, I noticed his top fin was a little rigid and had a tiny tear in it. I also saw that his left fin looks like the cartilage has been torn.
<Likely from tussling with the Dottyback>
He can still swim fine, but I am concerned. I also saw that one of his bottom fins looks like half of it was sort of snapped off. I also see 2 whitish lines back above his eyes, but I don't know if they were there before. Could these characteristics be from the Pseudochromis or could it be an infection of some kind?
<Both, from one, then the other... will likely die if not removed, treated elsewhere>
I am very concerned and if you have any advice, please let me know. Thanks!
<... as time goes by you'll understand how little useful information you have provided here. Please, do yourself and your livestock the favor of educating yourself. Don't rely on a consultant, me... read. Bob Fenner>

Skunk Cleaner Shrimp vs. Dottyback - 2/20/2006
Hi crew!
<<Hi Chris.>>
I'm just researching the possibility of adding a Lysmata amboinensis to my 30gal (UK) FOWLR tank. I have 2 Tank Bred Amphiprion ocellaris and a Pseudochromis porphyreus, a few Nassarius Snails, a Bumble Bee Snail, a Super Turbo and a Blue Legged Hermit Crab along with a few Actinodiscus and a very small Sarcophyton.   
I really wanted to know if it's at all likely that the Dottyback would eat or attack a skunk cleaner. I think it would make a really cool addition to my tank, but I don’t want to add one if it's likely to end up as an expensive meal for my Dottyback. I've looked through the FAQs but no-one seems to have asked the question.
<<Tough call.  I have never personally had a problem with this fish and shrimp. That said, some have.  If I were you, I would remove your Pseudochromis to a quarantine tank, add the shrimp to the qt, and watch carefully to see how the fish reacts.  This way if it goes poorly, you can more easily separate the two without having to tear apart your display tank.  Just a suggestion.  Alternatively, add a larger shrimp, watch closely, and be prepared to separate/lose a shrimp.>>
Thanks again for a fantastic resource. Whenever I'm planning something for my aquarium I always spend a few hours/days trawling through the WWM site, reading up.
<<Me too.>>
Warm Regards,
Chris.

Orange wolf eels and fuzzy dwarf lions  1/8/06
I have a 55-gallon tank with live rock. I recently introduced a wolf
eel. I know this Dottyback is often referred to as a "green wolf eel,"
<Yes>
but this specimen is bright orange -- not brown -- with aqua-colored markings. Is that coloration unusual or is it what is meant by a brown female?
<Is unusual... perhaps a female>
It is a gorgeous fish but highly aggressive. The LFS guy assured me that the wolf eel would not bother my fuzzy dwarf lionfish, but it
certainly freaked it out, and the FDL started hanging out at the top of the tank, even upside down at times, and hanging onto the protein
skimmer. After a couple of days, things seemed to settle down in the tank, and the FDL moved around the tank more, back on the rock at times,
but still very wary of the wolf eel. Then two things happened. The FDL ate a feeder goldfish that was meant for the wolf eel (having read your
site, I now know to train it to eat other foods), and it took most of the day for the FDL to fully swallow a fish that was not that much smaller
than itself. The next day the FDL was dead, resting on the bottom and looking much whiter than it had in life. Your website talks about cyanide
poisoning as a possible cause of death (we had had the FDL only about 10 days before introducing the wolf eel), but I wonder if either the
goldfish or stress caused by the wolf eel are more likely causes.
<Scorpaenid fishes are easy to collect... cyanide isn't used on them. The other inputs are of more import here.>
My family would love to replace the FDL, but I wonder about its compatibility with the wolf eel.
<In this size system, considering what you're written re the behavior of this Dottyback, I wouldn't>
Thank you for your help.
<Welcome. Bob Fenner>

Re: Orange wolf eels and fuzzy dwarf lions   1/11/06
Dear Bob and WWM Crew -
<Franck>
Thank you  for the helpful response. Your site is a remarkable source of information -- I just wish I had heard about it before I started. The LFS
guy directed me to your site over the weekend as the best place to get answers on-line, and I was proud to be able to say I was already familiar with the resource.
<Ahh!>
In my previous email, you suggested that another dwarf lionfish may not recommended for my 55-gal set-up given the aggressive wolf eel.
<Correct. Have seen some of these that were pure terrors. At any length it is likely that the "Wolf Eel" would eat most all food placed in the tank>
Is there anything else that you could suggest to a novice that might thrive?
<The choices are vast here... and covered to a degree on WWM>
In addition to the Dottyback, I have a coral banded shrimp, a percula clown, and three surviving starter damsels (the Dottyback got the fourth). I
have about 25 lbs of live rock sitting on a thin layer of 20 lbs. of live sand. One other odd question -- does the wolf eel produce large "droppings"?
<Yes. Can>
I have found occasional soft black lumps on the bottom, and I can think of no other source. I assume these need to be scooped up immediately -- I
just never heard of this as part of maintenance process!
Thanks again.
Franck
<Happens. Bob Fenner>

Pseudochromis fridmani aggression 11/1/05
I've read that the tank-raised Dottybacks are less aggressive but I still am not sure if they would be compatible with my tank. 
<They generally adapt better to confined systems and the social life of tank mates that occurs in captivity in comparison to their wild captured cousins. However they are instinctly territorial and have the potential to be quite aggressive.> 
I currently have a 100 gal setup with:
1 Firefish
1 court jester goby
1 powder blue tang
2 tomato clowns
1 cleaner shrimp
2 sexy shrimp
What problems do you foresee? 
<Possibly a little aggression toward the Firefish though since it is already established and this tank is on the side you may be okay.>I am a little worried about the sexy shrimp and the Firefish. 
<The sexy shrimp could definitely fall prey to a larger specimen.> 
I know he would be added last - does this also minimize aggression?
<Minimizes the chance of aggression but not a guarantee.>
Thank you,
Marlana Marks
<You are welcome, Adam J.> 

Pseudochromis vs. Clowns 10/18/05
Hi WWM Crew!
<Hello Steve!>
First, my compliments on your fantastic site...the knowledge contained within its pages has proved invaluable time and again.
<Glad you have found us useful.>
I was hoping to get your advice on my current situation with my, normally, very peaceful fridmani. Recently, I moved two tank-bred A. Perculas (born June 16) 
<Little guys.> 
into his, and he's having difficulty accepting the newcomers. 
<Not surprising honestly.> 
Previously, his only tank mate for over two years, other than the assorted cleanup crew and a cleaner shrimp, was a yellow goby (Gobiodon okinawae) which mysteriously disappeared a few weeks ago. 
<The fridmani had a territory (tank) to himself the addition of new fish is going to upset him.> 
I knew there would be a possibility that he could act aggressively towards newcomers, 
<More than a possibility, more like a likelihood.>
but convinced myself that the chances would be very slim considering his past behavior, the fact that there's plenty of hiding space in this 30-gallon reef tank,
<Its not a physical space issue it’s a psychological space issue.>
and that fridmanis and Perculas normally get along admirably. Well, so much for my reasoning! 
<Personalities are unpredictable at times with fish and people.>
At any rate, the fridmani seems hell-bent on keeping the two Perculas trapped in a corner. 
<Not pleasant for the perks, could lead to stress or feeding strikes.> 
He does sometimes charge into their midst, but I have not observed him actually nipping at them, and don't believe he's making any physical attacks. 
<These psychological attacks can be just as damaging over time.> 
When I approach the tank, he seems to know instinctively that he's misbehaving and will retreat into his favorite cave. With the fridmani out of sight, the Perculas will immediately leave their cover and seem to enjoy exploring their new environment and playing in the outflow from the water pumps. After I've "intervened" and they've been released from hiding, I've noticed that even after I retreat, they will "stand their ground" and not allow the fridmani to chase them back into the corner so easily. They don't actually go after him, naturally, but they do seem to exhibit some teamwork 
<There is strength in numbers being in pair is better than being alone.> 
and will "stare him down" for a while. Nonetheless, two or three times a day (this is only their second day in the tank), I'll have to come over to the tank to make the fridmani retreat (I don't actually do anything other than walk over to it and stand there for a few minutes). BTW, it was always normal for this shy fish to retreat when anyone approached the glass, even at feeding time.
<Yes these are instincts.>
Do you believe the fridmani will begin to accept his new tank mates given some time? 
<He could but its also possible he could become bolder and begin attacking even more.> 
If so, how long should I tolerate this before intervening in a more drastic manner? 
<You should be intervening now, I was going to suggest re-aquascaping but I see that’s not an option.> 
Unfortunately, I can't rearrange the LR, or I would have done that today. Should I pull the fridmani out for a while and re-introduce him later? 
<That would be my second choice, move the fridmani to your quarantine tank for at least a week maybe longer.> 
Naturally, it would be quite some feat for me to actually capture him (can't really move the structure as I mentioned; LOTS of hiding places; and he's not only fast, he seems to be rather intelligent as well). 
<I understand.> 
Obviously, in the worst case, I know I'll have to pull the Perculas out. 
<Yes.> 
However, even though when it comes to fish I've always felt that fewer was more, I really didn't want this to become a single fish tank, especially since he is rather shy. 
<I understand.> 
But, if he can't come to terms with these, I can't imagine him accepting any other fish that I'd be willing to introduce to the tank.
<In all honesty the chances of the fridmani settling down are not good, you are going to have to intervene in one way or another.>
Suggestions?
<You would try your best to temporarily separate the fridmani.>
Thanks and Cheers! Steve
<You’re welcome Adam J.> 

Purple pseudo and percula tank raised Help  9/19.5/05
I am a novice, I love your site it has taught me a lot.  i recently added a purple pseudo to my tank, with a percula  I have LR and all that my clown was healthy and happy.  The fish store guy suggested this purple pseudo as a good match but he seems quite aggressive and keeps nipping at my clown his bottom fins are getting torn what should i do,?
<Separate them... ASAP>
my clown is very friendly and feeds from my fingers.  I feel when i go to the fish store they are only helpful if you know what your talking about,  it's hard to be a novice and get good advice, but I actually love my SW tank and plan to expand to get a rose tip anemone later down the line. After i know what I'm doing.   Can you please help!!!!
<Keep studying, thinking critically my friend. You'll do fine. Bob Fenner>

Royal Dottyback- A Royal Pain?
My wife and I have had some bad luck picking fish lately. Our first fish died a couple months ago (it was a Strawberry Basslet). When we finally got the courage up to get something else... we got a Bicolor Basslet and a Diamond Goby. Things went well for a couple days. Next thing I know my goby is on the ground dead. I think my Basslet bullied him out. The reason I say that is this: I went back to the pet store and got a Sixline wrasse. Sure enough, Basslet bullied him.
<Hey - you really need to quarantine new arrivals for a few weeks before placing them in you system. It can make the difference between success and failure!>
My wrasse didn't jump out, but I can't find him. I've been told a six line wrasse will hide in the rocks.
<They can. I had one disappear, only to be found thriving in my overflow box months later, apparently none the worse for the experience!>
Still, I'm paranoid he's dead. So I pick up every rock, but don't see him. I guess something ate him.
<These fishes are very adept at hiding, in rocks, substrate, etc. I wouldn't give up just yet.>
(combination of Basslet, shrimp, serpent star, crabs.. who knows) Now my question is this. If my wrasse did die, what fish can I possibly get... that my Basslet wouldn't bully, or at the very least could stand its ground against it?
<If you are referring to the "Bicolor Dottyback" or "Royal Dottyback" (Ahh.. the danger of using common names), Pseudochromis paccagnellae, then you are dealing with a fish that, is a real behavioral problem in many tanks, as you seem to be finding out. You'd be best to stock the fish with larger, more aggressive fishes that can hold their own.>
And do you think there's any chance my wrasse is still alive? I saw him yesterday morning.. but not since. (I have about 40 lbs of live rock in a 29 gallon tank.. and I picked up every rock to check.. but I guess I could have missed a crevice here or there??) If you can offer up any advice, I would greatly
appreciate it. Thanks. Neil
<Well, Neil, it's hard to say...There is very likely a chance that he's hiding and will emerge soon.>
PS: in case you need specifics about my tank and what's in it.. here goes:
29 gallon tank
40 lbs live rock
1 Bicolor Basslet
1 Sixline Wrasse (I hope)
1 feather duster
1 Serpent Star
1 Coral Banded shrimp
about 15 hermit crabs (mix of Blueleg and Scarlet)
about 15 snails (mix of Turbo, Nassarius, and Cerith)
2 Sea Cucumbers
Oh.. and last I checked, which was just a couple days ago.. pH was normal.. and there was no ammonia, nitrates, nitrites, phosphates, etc. (I've had the tank about 5 months).
Again, Thanks for your help.
<Glad to be of service! Keep looking! Regards, Scott F.>

Dottyback Compatibility
Bob, 
<James, for Bob today>
First, I would like to thank you for your contributions to this great hobby!
<You're welcome>
Your work has helped us out tremendously. Now to the point. I am setting up a new 125 and moving the rock over. After a couple of months to stabilize, I would like to add a couple of Dottybacks. One would be the Orchid, the other the sunrise. I plan on about 120 lbs of rock or so. I believe I now have about 80 and the rock is all from the Marshall's. It is going to be a Marshall Island biotope. I have not decide on fore or back reef. The dotties would be captive bred. In this type tank do you think the 2 dotties would work? If not, what would you suggest as the minimum size tank for maintain these fish together? Thanks for your time and contributions. 
<Steve, it would be the equivalent of putting two male freshwater Bettas in a tank together. Read here. http://www.wetwebmedia.com/pseudoch.htm. James (Salty Dog)> 

Dottyback Compatibility - II
James,
Thanks for the reply. I guess I won't be doing that! I have read all the FAQ's and I couldn't find a minimum tank size to house 2 dotties. Do you have a recommendation? 
<Steve, it's just not wise to put two dotties together. They are great scrappers with others of their kind. James (Salty Dog)> 

Dottyback Compatibility - Oh no you don't!
James,
Thanks! I hate when I can't do what I want ;-) I won't even think it again.  I appreciate your looking out for the best interest of the fish!!! 
<And your wallet. James (Salty Dog)> 

Wrasse Vs. Dottyback?
Do you have any specific recommendations for fish that are generally larger and more aggressive than my Dottyback? Thanks.
<Well, I'd look into some of the larger Halichoeres species of wrasse, such as H. ornatissimus or H. marginatus. They are cool and can hold their own! HTH! Regards, Scott F.> 

Killer Dottyback or?
Hi Crew, I need some advice about my large yellow Dottyback. I purchased her a short time ago and was assured from the local saltwater fish store that she would not disrupt my reef tank. Well I am seeing changes here. A 55gal tank with about 100lbs of live rock. A clown, Chromis, 2-damsels. Multiple small corals of all sizes and shapes. My big question is I am now missing a few of my Astrea snails, and I haven't seen any of my Stomatellas and my 2-cleaner shrimp are missing as well. 
I have started to feed her frozen meaty foods and have noticed how aggressive she is with shrimp and squid pieces. Is she the culprit and if so is there any way to trap her without taking all the rock out of the tank and disrupting the growing
coral I have in there now? Thanks Lacee22
<Mmm, could be the Dottyback, but I'm wondering if you have another critter... a Mantis Shrimp, Pistol Shrimp, perhaps large worm... at play here. I would buy or devise a trap (these are gone over on WWM... you can use the indices or search tool there) and a flashlight at night to investigate further... Bob Fenner> 

Dottyback and Firefish in a Small Tank (6/5/05)
Perhaps you can help me, I have had a 10 gallon reef tank going for about 4 months. Everything is great.  But this weekend we picked up a Firefish. The day I got him I acclimated him and put him in the tank. After a very short time, the Dottyback (Pseudochromis aldabraensis) was attacking him. <Totally within what should be expected from this very aggressive fish, especially in such a small tank.> He would come from under the LR attack and go back again. Probably attacked about 10 time in 10 minutes. So I put the Firefish in a plastic container with holes in it, and just floated him for 2 days now. Maybe this way the Dottyback can get use to the fire fish. <That will not happen. Expect exactly the same if you release the Firefish into the tank again.> I added the Dottyback and my percula clown together and they are both fine together. <The Dottyback will attack any fish of similar body type such as Firefish, gobies, royal Gramma. They have been known to eviscerate and kill fish larger than themselves.>  I also have a peppermint shrimp that's fine.  Can you tell me if
I can successfully add the fire fish to my tank? Thank you, Ron <Sorry to say this Ron, but I highly doubt it. Your tank is too small and the Dottyback is too aggressive. If I were you, I'd remove it. I'm not sure you'll be able to get any other fish in there with it now, most especially a Firefish. Consider replacing him with the safer Royal Gramma. With the clown, a Gramma and the Firefish, this tiny tank will be full. There are other options for stocking, but 10G can really only handle 3 or 4 small marine fish. Hope this helps, Steve Allen.>

Dottyback Compatibility (6/8/05)
Thanks a lot for your quick and informative answer! <My pleasure. Pre-flight insomnia keeping me up late. Steve Allen again.> And what if I would replace the Randall's Orange stripe prawn goby (Amblyeleotris randalli) by an Orchid Dottyback (Pseudochromis fridmani)? <It might well kill your Dragonet and Firefish.> Just a thought...Thanks! Dominique <While Orchids are a bit less aggressive than others, Dottybacks are well-known for vicious aggression. It would be a bad idea to put any Dottyback in the same tank with timid fish such as Firefish and Dragonets. Not worth the risk.>

Pony Pals... Seahorse compatibility (7/9/05)
I am currently in the process of starting a 77 gallon seahorse tank.
<Congratulations! Seahorses are my absolute favorites!  This is a very nice size for a seahorse corral. Please do look into stocking your tank with captive bred seahorses. They are a healthier, heartier and an environmentally friendlier option. In addition the reliable breeders will have them trained to accept frozen Mysis, so that feeding is not as challenging and costly as feeding their wild caught relatives. There are a few reliable sources these days>
I am looking for suitable tankmates for the seahorses.
<You can find a list of suitable pony pals on syngnathid.org…..
http://www.syngnathid.org/ubbthreads/showflat.php?Cat=&Board=FlatMates&Number=824&page=0&view=collapsed&sb=5&o=&fpart=1>
I learned from seahorse.org that Firefish could make a good addition to my tank.
Yes they make an excellent seahorse companion. I had a pair of purple Firefish Nemateleotris decora for years.>
My question is does that hold true for the purple tilefish, which is in the same family?
<Actually the tilefish are in the family Malacanthidae and Firefish the Microdesmidae family. Tilefish historically have a very poor survivability. You can read more about the tilefish here…..http://www.wetwebmedia.com/tilefishes.htm.
If you are interested in something that is purple you have a few options….. There is the purple Firefish Nemateleotris decora, which you can have a look at here http://www.wetwebmedia.com/dartfish.htm. The Orchid Dottyback, Pseudochromis fridmani which you can have a look at here http://www.wetwebmedia.com/pseudoch.htm.
The Dottybacks typically do not make suitable tankmates for seahorses but the Fridmani Pseudochromis is an exception to the rule. They are also available captive bred which is a very nice advantage. However,  beware not to confuse this fish with Pseudochromis porphyreus the Magenta Dottyback which has more of the typical Dottyback personality which would not be appropriate with seahorses.
Then there is the Black-Cap Gramma, Gramma melacara which you can have a look at here http://www.wetwebmedia.com/grammas.htm.
You can find additional information and support at www.syngnathid.org. Best of luck with your new seahorse corral, Leslie>

Questions about Dottybacks  9/2/05
Hello there. <Hello Rick> I have a few questions about the orchid Dottybacks. <Nice fish> I’m so tempted to buy one, but I want to make sure it won’t dismember my other fish. I have 3 damsels and a clown fish. Will an orchid Dottyback be ok with these fish? How will it affect the other fish. My two yellow tailed damsels are already used to being bullied around by my blue damsel and my percula clown fish is very territorial to his anemone. If anything I think my blue damsel and clownfish will be fine with a Dottyback but my yellowtailed damsels are very shy.  Thank you so much!!!
<Rick, the Dottybacks shouldn't bother any of your fish providing there is no overcrowding in the tank. The blue damsel may have a few rounds with the Dottyback but if you have plenty of hiding spots (caves, etc), you should be OK>  Male Dottybacks are aggressive toward each other so stay away from that.  James (Salty Dog)>

What do you think about eventually adding a Dottyback to my FOWLR which has a royal Gramma in it? War? I was thinking about a neon or an orchid.
p.s. the RG is doing very well with all of the bigger fish. They leave him alone and he travels all over.
>>
Some Dottybacks (Pseudochromis) can be tough as species and individual specimens, but both the Neons and Orchids are pretty mellow and consistent... as a consequence of being largely tank bred and reared (versus wild-collected). I say "go for it", but keep your eyes open...
Bob Fenner

Re: New Mini Reef Set up....
Ok Robert I've got another question for you, So, I took my blue devil and put him in the little breeder box, rearrange the tank completely and let in my 2 new fish, a skunk back Pseudochromis, and a peppermint goby into the tank.. once it was obvious that they were fine and settled and eating, I let the devil loose... he immediately started going after the Pseudochromis, but the Pseudochromis has been putting up a good fight and hasn't suffered at all, and actually has taken a little out of the tail of my blue devil. The situation stands now with the blue devil keeping watch for the Pseudochromis, but not really doing any harm... do you think I should see if he gets bored of this and gives up or should I just remove him from the tank now???
I'll need to do that before my fiancé gets home, she's gotten kinda attached to the fish! :-) maybe I'll get a green Chromis instead....
what ya think?
Thanks!
DAVE
<All actually sounds like it's going "as planned"... a stand-off of sorts is really what you/we can best hope for... and detente seems to have been achieved... these alpha type species are doing about what they will... and likely won't kill one another off at this point... The "loser" of the hour, minute, day can/will hide out for a better chance next time... As long as they're both getting food... and I wouldn't add any more fish/fighters to this milieu... until/when you can enlarge the "arena".

Dottyback
Dear Mr. Fenner,
Once again I have to ask your advice, this time rather urgently:
In a 55 gal. w/LR I had a Yellow Tang, 2 tank-raised Ocellaris clowns, and a Blue Damsel. In anticipation of a new specimen I removed the Damsel to another tank. Although I had planned to purchase a Coral Beauty Angel this weekend, I was dissuaded by the LFS who insisted that I needed to acquire more live rock (I currently have roughly 25 lbs. and am adding 10 lbs. at a time) and better lighting (to encourage macroalgae growth) before purchasing the Coral Beauty.
<Good for them. Good advice>
Another fish caught my eye, what the LFS referred to as a tank-raised "New Holland Basslet." Although I was unable to find the species in any of the guides I consulted, I made the decision to purchase the rather expensive specimen based on information about Basslets in general. This was a mistake, and I could not feel more penitent.
<You should...>
I found the fish (a Dottyback, actually) on your site eventually (I should have looked here first, I realize) and have learned that in the wild it can reach 7.5 inches!
<Yes, and sometimes become an unholy terror...>
I am not planning to introduce any more fish into my system BUT I am greatly concerned that this fish will bring stress and strife to my developing reef.
Should I return it now, consider it a lesson and find a more docile species, or should the Dottyback do well in my system? There are many shell and coral hiding places, but the False Percs are hardly an aggressive species. Help! (I suppose I could remove the clowns, return the damsel to the tank, and keep an "aggressive species" tank?)
R. Duff
<If it were my system, and I intended to add the Coral Beauty and/or keep the peace, I definitely would trade this specimen back in. Too much possibility for trouble.
Bob Fenner>

Re: Dottyback
Dear Mr. Fenner,
I recently wrote requesting help w/an aggressive Australian (New Holland) Dottyback.
Despite my incredibly stupid purchase of a fish I had not researched (but was recommended by my LFS) all is well, I removed the fish easily and returned it to the store for credit which I used for more LR.
So no urgent action is necessary. Sorry for the bother, it is absolutely mystifying that despite the advice of many respected sources I purchased a species I was not familiar with, a mistake I will not repeat.
R. Duff
<Never a bother, and glad to hear this Pseudochromis novaehollandiae is on its way to a happier, more compatible setting.
Bob Fenner>

Dottyback
Hi Bob! Long time no chat. I emailed you earlier to let you know I thoroughly enjoy WWM. Now my dilemma.
<Hmm>
As you may recall, I struggled in finally deciding to add a Kole tang to my tank. I found a nice one at a LFS that was eating and he is doing great. He has made his place among the other tangs and everyone is getting along fine. I intended for the Kole to be my final fish. But you always see something new...
<Human nature>
I saw a splendid Dottyback, Pseudochromis splendens today and I was wondering how this fish might get along with my current tank population. My current tank inhabitants include 2 yellow tangs, purple tang, Kole tang, blue-sided fairy wrasse (C. cyanopleura), sand sifting goby, one yellow-tailed damsel, one maroon clown (he finally got his bubble-tip and both are in marital bliss...), and three bicolor Chromis. (Oh, I almost forgot--you probably don't remember the details of my system, but my tank is 180 gallons, 30g sump and 10g refugium.) I also have various softies, 'Shrooms, LPS, a few SPS frags and a new 2" T. maxima among other cleanup crew inverts.
<Should do fine with this mix... this Pseudochromid is likely tank bred, reared... and for the family of Dottybacks quite easygoing>
I've read up on these guys and note that they're generally little devils as far as territoriality goes, they like to jump and they should be added last or next to last. Also that they are ich-prone. But they seem to be very neat fish, always darting around. The specimen I saw was about 1 1/2 inches long or so and seemed pretty active. Based on my experiences with adding fish, I'd be most concerned with the ability of this fish to fit in with the bicolor Chromises and the yellow-tailed damsel--I'd perceive these of the current inhabitants to possibly present the most risk with this addition. (The yellow-tailed damsel is the smallest fish in the system and never picks on anyone else, but he really does like to pick on new additions until they put him in his place...)
I really like the fish, but I really don't want to too terribly disrupt the current tank population as everyone has their "place" now. I also have never had an ich outbreak and that's always a risk--I'm assuming that you'd recommend FW dip/QT for this specimen? Or just FW dip?
<I would quarantine the fish per our sites recommended protocol... barring this, at least a pH-adjusted freshwater bath as spec.ed there, yes>
Also, as far as color goes, is it the norm for these fishes to fade out in captivity, or will they thrive and keep their color with good water quality and a varied diet? (If fading out is the norm, then the reward might not justify the risk.)
<This species is relatively "color fast">
I'm just ruminating on this one for now. I'm inclined to pass on it just from the potential risks of adding a fish and the risks specific to this genus of fishes, but I'd appreciate your thoughts as always.
<Be chatting my friend. Bob Fenner>
Thanks again! --James Deets

Neon Dottybacks
Hi,
I just return from the Western Marine conference where I heard your presentation and in it, (not the topic but) you mention some compatibilities between fishes. I have a question about the neon Dottybacks: I am very impressed with this fishes and I would like to have some of them (tank raised) but, how many could be put together in a 180-G tank without too much aggression?
<Hmm, tank-raised? I would go with three or four individuals...>
Thanks in advance for your help and indeed, as someone mention in the presentation, you have a GREAT website.
Jorge S.
<Thank you my friend. Be chatting. Bob Fenner>

Re: Dottybacks
Thank you for responding to my e-mail. I'm not sure how much e-mail you get, but I suspect that it is quite a bit.
<Yes, a bit>
I had to put the diadem Dottyback in my quarantine tank, it started attacking the royal Gramma. 
<Yes, very common... similar, too similar appearing, habitat>
When I first put them in the tank, the Gramma chased the Dottyback away from my larger group of rocks. (I don't have much rock in yet, about 4 pounds. I am building up my live rock slowly.) I noticed today that the Gramma had some frayed fins so I watched them for a while and observed a fight. I spent an hour trying to catch the dotty (they are fast little buggers) before I finally caught him. I am thinking from what you said in your e-mail that I will have to take him back and wait until I have more rock before replacing the Dottyback.
<Yes>
Thank you again.

<You're welcome. Bob Fenner>

Dottybacks
I recently purchased your book "The Conscientious Marine Aquarist" and am enjoying it. At the same time that I bought your book, I purchased a Royal Gramma and Diadema Dottyback for my two month old 55 gallon system. I think that I would like to add another Dottyback to the tank, perhaps a Sunrise Dottyback, and I was unsure from your book whether that would be possible.
Are you limited to one Dottyback per system or one of each species of Dottyback. In addition to the fish already mentioned, I have two percula clowns in the tank. All are from the same LFS and are tank-raised from C-Quest.
<Thank you for writing! The limit "per tank" of Dottybacks/Pseudochromids is a measure of three main factors: the size of the given system, the amount of rock/cover, and the given species of Pseudochromid... on the latter, some species are literally terrors... killing not just other Dotty's, but most any other fish in its assumed territory. Diademas are amongst the "more mellow", smaller species available, and the tank-raised Sunrise is a virtual marshmallow... If this tank were twice the size and has lots of cover, I would give you 50-50 odds of them making an uneasy truce... a fifty five though? Not a good gamble.>
Thank you for your time and excellent book.
Jeffrey P. Schulz
<Thank you my friend, do take a look at the Dottyback materials stored on the site: www.WetWebMedia.com Bob Fenner>

Blue-barred Dottyback
I have always wanted to try a Dottyback but I was waiting for the right one.... hopefully this one. I have a semi reef tank with a few anemones, hermit crabs, a variety of snails and fish, the largest of which is a 4" truncate Anthias (have seen one of these for sale?)
<Yes>
I purchased a blue-barred Dottyback (Pseudochromis cyanotaenia) yesterday with the thought that he might just fit into my community, although I am worried about the six line wrasse....they have flashed at each other, but there seems to be little problem, there is a lot of rock in the tank. I am a little worried about one thing, both books I have mention that this is a difficult species to keep but not why. 
<http://www.fishbase.org/Summary/SpeciesSummary.cfm?ID=14
Not one of the "meaner" nor larger species of Pseudochromids... I don't have a pic, or much info. on this species: http://www.wetwebmedia.com/pseudoch.htm>
So far the little guy has been a whirl wind of curiosity checking everything out all about the tank and eating right along with the other fish. The Anthias chased him once (he had to make sure the Dottyback knew who was boss!) and then has pretty well ignored him. (the Anthias likes to initiate all new comers... will this be a problem when I finally find him a buddy?). 
<The Anthias? Likely so... you don't state how large this system is... please read over the Fancy Basses materials posted on our site: www.WetWebMedia.com

Any other info I can find would be wonderful.
Thank you

And the Dingo ate me Baby
Dear Bob.
I hope this finds you well and in good spirits. Quick one today.
<Okay>
I have just come back from a lecture this morning and have discovered to my horror that a hermit crab and the CBS the one that you recommended trading :) have been EATEN!!!. There are pieces of fore-claws and hermit crab legs over the bottom of the tank. Apparently the CBS had molted last night as his exoskeleton is still near him. Not sure what happened to the hermit crab.
Quick review of the culprits. Would it be;
a. The tomato clown.
b. The Scooter Blenny.
c. The two fire gobies.
d. One of the Two Cardinals, Banggai and Pajama.
e. The Royal Dottyback
or last but not least, the Yellow Tang, who was always letting the CBS clean him. Please circle your choice :)
<Almost certainly the Dottyback (Pseudochromid for browsers of elsewhere)>
In mourning and do not want to run out and buy another Shrimp esp. the more expensive ones so that they can become Fish Fingers so to speak.
<Yes>
Oh and while I am keeping it short :) I have a quick question about the Pulsing Xenia. When we got it it was a whitish color and was pulsing away like mad. Now that it is in the larger tank it has changed color to purple and the polyps no longer pulse. It retracts at night, and seems to be growing longer day by day. There are also numerous small colonies sprouting up from the two larger stalks.
<Stress symptomology... you do use iodide occasionally? I would... and add something in the way of wash/food about the area (while temporarily shutting down skimmer/s, mechanical filtration? Please read: http://www.wetwebmedia.com/xeniidfaqs.htm>
And also if you could settle a dispute that would be really helpful.
After moving all of the live rock into the new tank about two weeks ago, everything was fine. Now the new coral substrate and everything is becoming covered with a layer of emerald green "algae" as well as on top of the green layer large spots of Maroon and Purple "algae" are developing. The argument is, when I said that it was good algae, as opposed to the hair algae that the tang has disposed of, I was told it looks like it will turn into a swamp. Do I have too much light. I have 130 Gallon tank with 2 watts of power compact 50-50 per gallon.
<This is almost certainly mainly Blue Green Algae/Cyanobacteria... not desirable, not eaten by Tangs... Please read on WWM re its causes, control>
Ok leaving you alone now. I very much appreciate your time. Look forward to your reply. No rush so if there are more pressing matters please answer them first.
<Will do so. Bob Fenner>
Regards as always.

Terror in the tank
Dear Bob-
<You got Steven Pro this afternoon.>
You and your WetWeb folks have given me great advice in the past through both your website and your emails. I've written to you before about this fish, and your diagnosis was perfect. Thought I'd ask another question.
In my 30 gallon tank, I have two fishes a maroon clown(< 2") and a Diadema Dottyback (3"), plus a large coral banded and a couple of hermits. Everyone has been happy and healthy to date, and the fish have been together for over six months.
The problem is the Dottyback. He very suddenly decided "there can be only one" creature in this tank....and it's himself. I purchased more live rock and moved everything around in the tank. (except the fake fan plant that the clown fish calls home)
<A good idea. Too bad it did not resolve the problem.>
This calmed the Dottyback for a day or two, but now he's back at his old tricks. Knocking the crabs around, playing tag with the shrimp, but especially picking on the clown.
The clown for the most part tries to ignore the Basslet, and has not shown any signs except a minor nipped tail, but it's disconcerting to watch the charges of the aggressor.
<Not something to tolerate for long. Beyond the actual wounds inflicted there is the stress involved which may lower the Clownfish's immunity and allow for infection.>
What to do? I believe that the clown when larger, will hold his own (with maybe some payback), but that's down the road.
Should I consider an anemone?
<Not a great choice.>
More rock work?
<If you have less than 40 pounds, maybe more would help.>
Get a cat? (just kidding) A bigger tank is not an option right now as space is limited.
<What about another tank?>
One suggestion (LFS) is to get a Lunar Wrasse or something else to challenge him.
<A little bit of the old woman who swallowed a fly story.>
What's your advice?
<I would remove someone.>
BTW, the LFS I purchased the Dottyback from won't take him back. I've since found a new store with different policies. Unfortunately they don't sell Dottybacks. (for reasons I've already described)  Aside from his antics, the Dottyback is an extremely intelligent and amusing character.
Any insight would be most appreciated.
<See above notes.>
Thanks. Thom
<You are welcome. Good luck. -Steven Pro>

<Greetings... Anthony Calfo in your service while Bob refines his technique for the synchronized swimming team>
Can a Blue Spot Jawfish (Opistognathus rosenblatti) be kept with a New
Holland Pseudochromis (Obgilbyina novaehollandiae)?
<hmmm... somewhat of an odd mix. Although not competitive in niche, I fear that the famous temper of the New Holland Pseudo will be a long-term problem. The Blue spot jaw is not an easy fish to find... cherish it and work around it with more passive tankmates. Anthony>

Incorrigible Emperor and Tusk Update/Dottyback
Anthony,
I am a bit of a "fish stalker" I guess. I've actually talked people OUT of buying a small Asfur that I love because I didn't feel they would take good care of it. Too bad I have to work like the rest of the world so I can only go there on Sat. Well I was reading a section in WWM that I've never read before.......which is shocking! I was reading about the Dottybacks. I had no idea they were such bruisers. 
<well... most just pack a powerful punch for their small size>
The article says that some should be kept with large angels, triggers, etc. 
<actually most Dottybacks would be eaten by these fish. There are few that are truly large and tough enough to hang with the big boys>
Well I was wondering if one of these guys would mix well with my monster Emperor and my new Sohal. 
<hmmm... I suspect not worth the aggravation for either of you>
Before I went through this failed tusk experiment, I got rid of my Red Spot Goby, my purple tang (which is ironic because I ended up with another tang), and my Sergeant Major damsel. Now I have the Emperor, the Sohal, and Maroon Clown in a 75. 
<wow... the angel and the Sohal really should outgrow this tank within a year or die of complications from the crowding. The tank is simply too small my friend. Bob and the WWM gang are just getting back from the Red Sea and have images fresh in their minds of nearly 2 foot long Sohals and foot long Emperors... your tang does not need another fish. You may need a shoehorn soon however, to get them out... heehee. Really, though... you don't want these fish to suffer from the crowding...please do not add any new fish in the interim. Your big boys will grow so fast already no matter how small they are>
I was thinking that a larger Orange Dottyback would look great in there. Is it "too much" fish for my clown? I notice that aggressive natured fish tend to do better with the Emperor. 
<the tank size is definitely an influence>
The Maroon has never been afraid of him and as a result is the ONLY fish he's never gone after. The Sohal introduction could have gone horribly except for the fact that it got right in the angels face and as a result things have been pretty good....still the Emperors tank though. I have LOTS of liverock. 
<Ahhh... even less swimming space <G>>
I don't know how many lbs because I always get a piece at a time, but I'm sure it's way more then 50. Any particular Dottyback you would recommend? Or none? Thanks buddy. Rick
<yes, none... and I do not mean to sound too critical my friend. I know that you are a very empathetic aquarist. But do take the advice to heart. Best regards, Anthony>

Dottyback Intervention...
Mr. Fenner,
<Scott F. with you today!>
I have a question about housing two fish together. I'm not getting a good feel from what I'm reading. I've read that Dottybacks shouldn't be kept fairy wrasses, as the Dottybacks will even harass them.
<Ounce for ounce, these guys can be the nastiest fishes around!>
However, I've also read about how gregarious the orchid Dottyback is. Can I put an orchid with an expensive Cirrhilabrus species, or will they bother each other? 48"x18" 75g tank.
<The orchid, or fridmani Dottyback is definitely more sociable than some of its relatives, however, I'd still keep an eye on things and prepare to intervene if it becomes necessary. With plenty of hiding spaces and rockwork to create and divide territories, I think you should do okay. Perhaps you could add the Dottyback later in the game, or even last- to reduce or eliminate any potential problems. Good luck!>

There's A  New Dottyback In The Neighborhood
Pseudochromis diadema:  I presently have this fish in quarantine. Will it bother my fire goby in 55 gallon reef system?
Thank you, Miguel
<It's really hard to say, Miguel. Pseudochromids are some of the toughest fish in the ocean, ounce for ounce! If there are plenty of hiding spaces for everyone, there is a good chance that you won't have too much trouble with this combo. I would be a lot more concerned if you were adding the Firefish to a tank where the diadema was already in residence! With enough food, territory, and open space, this can work out. Do keep a close eye on things just to make sure, and take quick action to remove somebody if it becomes necessary! Take care!  Scott F.>

P. fridmani compatibility with Firefish and royal Gramma?
Hi bob (and crew!),
<Hola!>
I have a fridmani, a yellow tang, and two clownfish in a 65g with plenty of rockwork. do you think either a pair of Firefish or a royal Gramma would be bothered much by the fridmani?
<Mmm, too likely a problem with either>
I've heard the fridmani may have a more even temper out of the Pseudochromis family; have you had any experience mixing them with Firefish or grammas? thanks!
<Well, actually as the family of Dottybacks go, Fridmani are about "medium" in terms of territoriality/aggression (being tank bred nowadays), but still... they don't like fishes that are similar appearing or that occupy their niche. Bob Fenner>

Blue fish
Thank for the reply. I like the look of the Pseudochromis fridmani, but it sounds like it is pretty aggressive.  <You’re probably thinking of the pseudo. Porphyreus as the fridmani usually stays pretty peaceful.> Will I have trouble in the future if I introduce a new fish? <You should be ok as long as you don’t overstock.> I don't plan on adding other fish, but unfortunately they do die and need replaced eventually.>
While I have your attention, I'd like to ask you about a colt coral. I already have a Rasta coral, but I've read that the colt coral is somewhat  toxic in a reef aquarium. Is this true? Should I not add a colt coral?  <I’m not familiar with the Rasta coral but as long as it is a soft coral and they are placed at least 6” from each other they should be fine.  Cody>
Thank you for your time and help!

Dottyback in a small crowded space
Hi Bob and crew, you guys are the best. I have always wanted a Dottyback/Pseudo but I have been apprehensive because of their notorious personalities.  Just when I forget about them, I see one in the store that is just awesome to watch.  I thought that at the least I would ask you your opinion on the matter.  Currently I have:
30 gallon tank with:
45-55 lbs premium Fiji live rock
1 Halichoeres chrysus
1 percula clownfish (true)
1 pistol shrimp
1 cleaner shrimp.
1 Linckia starfish
1 Cryptocentrus leptocephalus
1 Midas Blenny
Assorted tiny blue leg hermit crabs.  All of the above fish are very small in size.
My question is: Could I add a Dottyback, and if on the odd chance it may be a possibility, would I be best off with the orchid Dottyback (because they are considered to be more docile than most)?
Could I add a springeri
Dottyback to my current tank?
<The Orchid would be better... but... your tank is really getting crowded... any chance of a bigger one coming soon? Bob Fenner>
  Thank you very much for your time.  You guys do a tremendous service to hobbyists and fish alike.

Marine fish compatibility
In the interest of marine life, and the expertise of WWM, could an orchid Dottyback co-exist with a fairy wrasse? I don't want anyone chasing anyone else in the tank. It's a 75g with lots of liverock.
Thanks
<likely fine under the circumstances... Orchids are quite peaceful... and enough fairy wrasses are too. The tank is large enough. DO be sure to QT all new fishes... if buying both at once, a clear divider in QT will give you your answer right quick. Best regards, Anthony>

Shrimp and the dotty...
07/15/03
<Hi James, PF with you tonight>
Hi, I want to thank all of you first of all for all of your help and support.  You all are doing a great job!  I have several questions for you.  I have a 75 gallon saltwater tank (fish only).  I have been considering getting a couple of shrimp but was told that many fish (even the peaceful ones I have) may try to eat the shrimp.  I have a pair of clowns and in the future plan on a bi-color Dottyback, a dwarf angel and a flame Hawkfish.  What are your thoughts about adding shrimp to a tank with these fish?  Are the fire red shrimp hardy and do they come out with the tank  light on?  How many would you recommend in a 75 gallon tank?   Also, Is there any type of butterfly fish that would be suitable
for beginners and are very hardy?  I was considering a pair of the black and white ones.  Thank you in advance for your help.
James
<Thanks James, it's what we're here for. On to your questions.
Shrimp and Dottybacks (well, most any fish actually) are a crap shoot. My two orchids lived peacefully with my cleaner and peppermints till I bought two more cleaners (in a 75g), and then they hunted them all down and ripped them to shreds. Go figure. The Hawkfish though, rules them out. It will eat them.
The fire shrimp come from cooler waters than most reef tanks, in the low 70's (there from deeper in the reefs (IIRC, under 100'), thus their higher price, red color, and preference for cooler waters.
As for butterfly's, I would recommend a Klein's Butterfly Chaetodon kleinii, hardy and they stay relatively small.
Have a good night, PF>

Pseudochromis fuscus
>I am in the process of stocking my 135 gallon reef tank with livestock.  I impulsively bought (zero research, I know, very stupid of me) a  fish sold as a "yellow grouper" over the weekend.
It appears that this a yellow Dottyback, Pseudo. fuscus. I would to eventually add cleaner (and other) shrimp to my tank. Will this fish eat cleaner shrimp (and others)?
>>This animal doesn't get very large, so I would think the different Lysmata spp. (and similar in size/habits) would do alright.  Of greater concern is interspecific aggression, watch this animal when introducing other fish!  Marina
>Love your site! Thanks in advance.  Dave

-Springer's pseudo-
Hey Gang, Hope y'all are having a wonderful day! <Actually, it's been raining ALL DAY LONG. :) > I recently bought a Pseudochromis springeri, it was sold as a "neon goby", for $15. <Oooo, sounds like a PetCo thing! I hope it was tank raised as they're readily available and hardy as nails.>  I've read conflicting info about these fish, everything from "nastier than Damsels" to "nicest fish in the waters". this one I got seems to be very peaceful & seems to be searching constantly for food, possibly bristle worms (?) <Been known to eat small ones> At this time, it's a tiny (1.5") fish that is a great addition to my 70g softy reef. What are Anthony's opinion, or any of the fine crew members <Fine Kevin at your service!> , regarding the species?
<I think they're great little reef fish. Could be a problem with fish of similar size, even a bit larger. They've even been known to gobble up a small shrimp here and there, so be wary about the size of new tank additions. Good luck! -Kevin>
Thanks, Scott in Denver.

-Green wolf eel with an appetite for flesh-
We're having a problem with our Green wolf eel. It has eaten 2 Lunar wrasses 1 4 inches and the other 6 inches. <Ouch!> The eel is 14 inches. Would a Niger Trigger fish be OK with it or can you recommend another fish? <Triggers are pretty precarious to swallow, but you may want to choose a more aggressive species. this selection would depend on the adult size of the trigger and the size of your tank.> We also have a Dog Face Puffer and a Yellow Eyed Tang. The Puffer and the Tang seem to be fighting
also. But I think it more of a territorial dispute since the Tang is new. <If the tank is too small, they may dispute indefinitely. Since the tang is new, however, a little bickering is expected. Hope this helps! -Kevin> Any help would be appreciative

Dotty back with a shrimp!
I've read that splendid Dottybacks can be know to go after some shrimp. Are any shrimp safe with this fish or would my skunk cleaner shrimps most likely be left alone? I have two of those and would like to keep them if you know what I mean.<I would say you should be fine, these guys are usually pretty peaceful. Cody>

Orchid Dottyback
Help!  
<Sure>
I went to my LFS and got an Orchid Dottyback.
After getting home I started doing some research (because I don't trust what the LFS salesperson says) and many sites are saying that I will have problems with the Orchid Dottyback when introducing new fish.
<That's the problem when you do research after you have already bought the fish. Always do research before hand!>
I don't know what to do.  I have a 55 gal, about 50# of LR, and only a tomatoe clown and six-line wrasse.
I just started this tank about 2 mos. ago.  
The guy at the LFS told me he would be fine but now I am worried. If I keep him in the tank what else can I put in with him that he will not harass?  
<Almost any fish will harass newcomers in an aquarium - it's a way to establish territory. Unfortunately, some of these Dottybacks can be quite aggressive to new tankmates. To prevent some harassment towards new fish, I would recommend redoing the rockwork right before you add in your new fish specimen. By doing so, the fish will both get an equal chance to get their territory which will therefore prevent fighting which may have occurred. Other than that, there's really not much else you can do other than to take the fish back to the pet store, or, to find a temporary home for the Dottyback until you have gotten the fish you plan to buy (Remember that it's important not to rush when buying fish. It can take several months to establish the correct biological load for some species of fish)>
Thanks for
your help.
<No problem. Graham.>

Steene's Pseudochromis
I recently purchased what I was told is a "Steene's Pseudochromis.  I've searched the web for information on this type of Pseudochromis and haven't been able to find anything.  Additionally I haven't been able to find a picture of a Pseudochromis that looks like what I bought.  
It's hard to describe a fish, but it's most distinguishing characteristic is it's yellow head and dark almost black body.  It also looks to have fairly large teeth, but it may just be the color of the mouth that appears to look like teeth.  
Have you ever heard
