Sailfin Tang needs to be moved ASAP  – 03/09/07
Hello WWM crew,
I hope all is well. I have a problem and I really could use some good advice. I have an acquaintance that recently had some sort of 'wipe out event' in his 90-gallon FOWLR setup (Most likely due to ignorance and neglect on his part). His only two surviving fish were a pencil wrasse and a sailfin tang. He asked if I could take the fish while he figured out what to do. Not wanting to see his fish suffer further, I agreed to take them and set them up in my 30-gallon QT tank. As it turns out, he will not be setting up his tank again (I believe due to financial reasons), but I now have these fish. Herein lays the problem. The pencil wrasse, after two weeks of QT has been a great addition to my 210-gallon reef setup, he appears healthy, is eating, and is always out scavenging (all good signs I hope.) My problem is that I don't know what to do with the sailfin. I have to get him out of my 30-gallon QT ASAP. He is still small, but I understand that Sailfins need plenty of swimming space and they grow very large. The issue is I already have a yellow tang and as these fish are from the same genus, they will probably not get along. I really hate to now give up this fish as my wife has really become attached to him, (he will feed out of her hand when she offers Nori).
Are there any proven techniques that I can try to get this fellow in my main display tank?
<<I usually suggest complete re-arrangement of the tank, but this is likely impossible with your set-up. >>
I know it is hard to predict what a fish may do, but this is an all or nothing effort. My tank holds 300+ lbs of live rock with plenty of caves and crevices. Once he is in, I will never be able to get him out. Any guidance or insight that you can provide will be greatly appreciated.
<<All can really suggest to make things more likely to go in your favour is do it just after lights out, perhaps distract with a feeding.  It really is a gamble.  I wish I had a more concrete answer for you, but there just isn’t one.>>
Best regards,
Dean
<<Good luck my friend. Lisa.>>

Brittle or serpent star? Bristly -vs.- Smooth.   2/25/07
Good evening!
I cannot seem to find the information on WWM or in the Reef Invertebrates book <See page 346> which tells the difference between Serpent Stars and Brittle Stars.  
<Most serpent stars have smooth arms where as most brittle stars have some type of spiny projections.  More here:  http://www.wetwebmedia.com/ca/cav1i4/echinoderms/echinoderms.htm  >
My FOWLR tank (45 gal, one Humu Humu Trigger, one Sailfin Tang, One Tomato Clown and one Yellow Tail Damsel) has been running since February 2006 and has had this collection of fish since the end of June 2006.  
<Sigh...  Here come the tang police...  The sailfin tang will get big, to nearly 16 inches.  Tank size should be a minimum of 135 gallons to provide enough swimming space.  Forty-five gallons is way too small long term for this fish.>  
Everything seems happy and healthy.  
<See above comment.>
A few weeks ago I saw a small star of some sort - center is about the size of an eraser on a pencil, the five legs are each about 1-1.1/2" long.  It is a dark gray-green color.  Legs appear to be smooth.  Is this a green brittle star?  How is a serpent star different?
<I suspect you have some mini stars in your system.  Either Amphipholis or possibly Ophiactis.  Both are beneficial detritivores that need little in terms of care and typical reproduce in the system.  I don't think there is any cause for concern.>  
I've only seen this guy three times in the last few weeks, at night after the lights have been out.
<Not surprising, most hide during the day.>
Thanks!
Judi
<You're welcome!  -Mich>

Re: Brittle or serpent star? TANG follow up   2/26/07
<Hi Judi, Mich here.>
You guys are fantastic.  Thanks for your prompt answers, etc.  
<Welcome!>
I did a fair amount of reading, etc, when I started my setup, but I also went to three different stores for advice.  I always told everyone the Humu Humu trigger was the main character I wanted, and then asked what else would work with it in the space I had.  The tang was suggested at the store I ended up buying a lot at.  The store is very clean with quite a range of stock and the owner seems quite knowledgeable.  After stocking my tank with these guys (damsel first - he was my 'canary' <cringe, are better ways to cycle> at tank start-up, then tang, then clown and trigger together at store owner's recommendation). I did find more info about tang on-line - AFTER I bought him - that made me wonder about my choice.  
<Always best to do your own research before you place any creature in your tank.>
He has grown in the 9 months I've had him = from about 3" dia to 4". I really like him, too; lots of personality.  He and the clown are like a married couple - kind of picking on each other all day but they sleep together at night:-) Bummer.
<Not a happily married couple here by any means!  Lots of stress.  Is worrisome.>
How quickly will he grow?  
<Depends on many factors.>
I have considered getting another larger tank in the future because I am enjoying this one so much, but it will be a couple of years before I can do that.
<I'm sorry to say but you may need to consider another home for this tang.  -Mich>

-Adding Tangs?  8/28/06
Hello, all.
<Evening>
I have kinda a long story. I used to have two saltwater tanks, each with it's own tang-a sailfin and a yellow. They were both about the same size. I upgraded the two into one larger one-150 gallons. I added the tangs at the same time, and watched them to see if one would need to be removed. To my surprise, they got along great. They swam together like old buddies all over the tank. Sometimes I would see them waving their tails at each other, but it seemed to me like very minor tiffs or just play fighting. (I've seen the yellow actually attack and kill another fish, so I know what that looks like.)
<Tis a tad small for them long term, but glad to hear they were doing well>
However, I just moved, and through my own stupidity, I lost several fish (I was lucky not to lose all of them) including the sailfin tang. The tank has now been set up for a week, and the yellow tang is really sketchy-very shy, always hiding in the rocks and not coming out much. It seems to me like he misses his friend. (and he's probably weirded out about the rocks all in different places.) Anyways, I was wondering if I should get him a new friend. I know tangs usually like to fight with each other, but if I get one right now, and of the same size and general shape, do you think they would be okay together? Or was my pairing a one in a million chance? I was thinking of either another sailfin, a purple tang, a blue tang or a powder blur tang. (Although I know the last two have disease issues.)
Thanks for the input!!
<I would follow what has worked in the past.  If a sailfin worked well before, it has less of a chance of fighting with the yellow due to the yellow's attitude.  That being said, your new tang might bully the old, so do watch out.  Your correct in your assumptions for the hiding probably, you did not mention how recent the move was, so I would check all the parameters closely.>

Sailfin Nipping at Corals 8/15/06
Dear WWM crew:
<Hi>
I have a Zebrasoma desjardinii that has started picking at my
Devil's Hand Leather, one of my Favorites spp., and a couple of my Xeniids.
<Not unheard of, but not very common either.>
I keep my fish well fed with various foods (Nori, Spirulina enriched brine shrimp, Ocean Nutrition's Formula 2, and live brine shrimp gut loaded with phyto/Selcon/Cyclop-eeze, etc.), so I'm at a loss as to why my prized, mainly-herbivorous, "reef safe" tang would start eating my corals.
<Forget the brine, even gut loaded.  Still not very nutritious, will probably be better off using Mysid.>
I don't want to have to relocate the fish, since I have had him for over a year, and have grown attached, if you know what I mean.
<Sure>
I was hoping you could give me your thoughts/recommendations regarding my situation.
<Well, you’re battling instinct here, so it’s going to be hard to change his behavior.  However this behavior could indicate a nutritional deficiency here, I would try switching up his diet some, forget the brine, switch to Mysid, and maybe try a few different brands of food, New-Life being my personal favorite, and see if it helps minimize this behavior.>
Thanks in advance,
Adam

Purple and Yellow Tangs?? Comp. of Zebrasoma    8/7/06
I am told through LFS's that Yellow and Purple Tangs need to be kept either one by itself or 3 or more, not just a pair.
<Best individually in small systems (under a hundred gallons), can be kept in multiple numbers in multiple hundreds of gallon systems...>
My question is can I have 2 purple tangs and just one yellow? Or will they gang up on the yellow? Tank is 125 with live rock.

-Sailfin Stocking-  - 5/7/2006
Bob:
<Justin with you today, but I was at IMAC with Bob>
I worked at IMAC (staff) last week but couldn't manage to get by your throng of admirers to say hi.  Next time!  You've been a lot of help with fish
recommendations and here I am again!
<Thanks for helping put on such a great convention/conference.>
I have a 150gal 5x2x2 tank, with a 150 sump and 75 fuge.  So lots of water.
My question has nothing to do with bioload as I'm fine there.
It's more a "space" issue in the display.
<Ok>
I have a 2.5" hepatus (grown from 1.5" in 2 months!) and a 2.5" or so Kole tang.
<Very nice specimens for a home aquarium.  Any fighting or territorial issues?>
I have an opportunity to acquire the most gorgeous sailfin tang I've ever seen.  Had my eye on him months ago but the store owner said he wasn't
selling.  Then he decided to sell to someone who is getting out.  I have "dibs" but need to do this responsibly.
<Yes, responsibly is definately the right word here.>
I know every individual will be different, so even if they are on paper compatible one can't control for that.  But in principle should these 3 fish
be ok in this size display?  My other fish are 3 Chromis, 1 radiant wrasse, 1 mandarin goby, 2 perculas and 1 royal Gramma.  This would be my last fish addition.
Thanks!
Joel
<Joel Ill be honest with you, If you can provide another tank for this specimen or one of the others should an issue arise, or if your LFS is willing to re-home one of the fish if there is an issue, then I think you should be ok.  I would definitely think this will be the Alpha fish in the tank, and certainly the last fish you want to add. Hope you have good luck with these specimens, but do keep a very careful eye on them once you add the sailfin.>
<Justin (Jager)>

-Sailfin Stocking part 2-  - 5/7/2006
Thanks!  This one has been extremely mild-mannered in it's current home. The ones in my tank are also fine
though at times the Kole picks on the Hepatus. That's changing as the latter grows, now they leave each other alone.
<Good to hear, the sailfin will probably  pick on them both to assert dominance as it is normally a much more aggressive alpha fish, so do be ready just incase.  Good luck and write back to let us know how things are progressing if it does go well.>
<Justin (Jager)>
Thanks, I'll give it a go.  Appreciate it!

SAILFIN TANG under Stress?  11/22/05
Hi. I Just added a sailfin tang to my tank, past Wednesday. It was sold as in good condition. But I noticed that it had a bulge in its stripes, just below its snout on the lower part of his body. The size is about 2.5 inches. It is not eating. I've been feeding the same as all the fishes in the tank, marine fish pellets. It's kept with a black percula clownfish, yellow tang, powder brown tang and a yellow tailed damsel, they are all peaceful with each other except the yellow tang which sometimes gets a little bit aggressive but doesn't do any harm. The sailfin doesn't move much from its territory,
<A clue that these tangs are not "getting along">
and I don't know if  I've seen correctly but it has eaten some of the other fish's wastes.
<Yes, natural. No worries>
I added a lettuce leaf to see, if it would at least go try it, but wasn't successful, although I didn't know i had to boil the lettuce leaf before introducing it to the aquarium. Also, I noticed like a white thing coming out of its snout, as if it had a tongue, I don't know if its a tongue or a parasite, or if its just blowing or what not which I don't seem to see in any of the other fishes. As you can see I'm a beginner, and its the first time I've had a problem like this. If you have any advice, i would appreciate it, because its a beautiful fish and wouldn't want to lose it..
Thanks in advance,
Frances Aviles

<You really should move this sailfin tang to another system, and soon. Though it may not appear to be "fighting", there is too much antagonism for it to live comfortably in this setting. Bob Fenner>

Zebrasoma Aggression  10/21/05
Hi all
<Hi Ignatio.>
I have an established 100 gallon reef tank with 8 juvenile fishes <What type of fish? Could be a little could be a lot. Big difference between juv. Chromis compared to juv. angels or juv. triggers.> healthy and one of them is yellow tang. 1 week ago I add 1 purple tang and unfortunately the size is smaller than yellow tang <Too small of a tank volume for these 2 fish, both psychologically and physically. Also in the same genus (Zebrasoma) a genus which has a nasty disposition to each other I might add.>, up to now the yellow tang is always chasing the purple tang
<Expected.>
but fortunately no sign of torn fins in the body of purple tang and up to now the purple tang wants to eat and fat (I feed them twice a day).
<Still not “healthy” for the purple to be subjected to such aggression.>
Note: when I feed them, the yellow tang is not bothering the purple tang, he just allowed the purple to eat together.
<During this short time the purple is not the priority to the aggressor.>
Do you think this problem will disappear between a month? <No, if you’re a gambling man you would bet on this to get worse with time.> what should I do concerning it is very difficult to capture the purple tang.
<Monitor them, if the aggression persists ultimately you will have to separate. Two adults Zebrasomas will likely not get along in this tank size, especially since one has been established for so long.>
Thank you & best regards

Purple Tang compatibility  10/19/05
Dear crew
I have an established 100 gallon reef tank with 8 juvenile fishes. And 1 of them is yellow tang. 4 days ago I bought the purple tang which is smaller than yellow tang. And after there was a conflict between them, the yellow tang is chasing the purple tang
but up to now the fins are all Ok and nothing damaged in the body of purple tang. And fortunately up to now the purple tang wants to eat. I fed them twice a day. When I feed them, the yellow tang doesn't bother the purple. Do you think this problem will
disappear lets say for 2 weeks or 1 month ? If not, what should I do? (concerning it is very difficult to capture the purple tang) <Tangs and their conspecifics <<Actually congeners in this case... RMF>> generally do not get along very well.  Larger tanks help quell this behavior.  Read here my friend.  http://www.wetwebmedia.com/purptgcomp.htm    James (Salty Dog)>

More Tangs (7-12-05)
I have a 120 g with room for more fish.  I have a 5" Sailfin tang and I want to add blue and yellow tangs. Should I add 1 of each or more and  what sizes would be best?
< I hate to put a damper on your plans but I would not advise adding any other tangs to this tank.  These fish should be placed last due to issues of territoriality.  So the addition of any new fish will most likely prove difficulty, with your Sailfin already well established in the tank. Here is a quote from Bob’s article on Sailfin Tangs http://www.wetwebmedia.com/zebrasom.htm
“Sailfins are better to keep just one individual of one species to a system . They can and will fight with their species and other tangs, seriously damaging other similar appearing fishes, even in tanks of hundreds of gallons. Should you be determined to keep more than one Zebrasoma or con-specifics together, do purchase them as a group, from the same dealer’s tank, and introduce them all at once. Per tang territoriality, these fishes should be placed last, affording their tank-mates time to assert space for themselves.”
You would be best to either leave well enough alone or if you are determined to add additional fish you can try rearranging the rockwork and décor or removing the Tang for a short while prior to introducing any new additions. Sorry for the disappointing news, Leslie>

Sailfin Tang and Flowerpot Coral
Hi Robert,
Hope this finds you enjoying the holiday season!
<Yes my friend, thank you>
I have a question about my Red Sea Sailfin Tang. He is about 5 in. and has
a voracious appetite. He will eat just about anything I feed to the
inhabitants, and immediately consumes all of whatever I place into his
lettuce clip. But lately I have noticed from a distance that he appears to
be nipping at the green Goniopora (flowerpot coral). When I go up to the
tank he will swim away, so I am not really sure if he is doing this or not.
However I discovered some of the tips of this coral appear to be missing.
The other tank inhabitants are 2 Ocellaris, some turbo snails, a few red-leg
hermits, 1 Lysmata wurdemanni, 1 Lysmata amboinensis, some (rapidly
spreading!) pulsing Xenia, and a Bubble-tip anemone.
Do these Sailfin tangs eat flowerpot corals??? 
<They can>
And if so, will this harm him? 
<If sufficiently nibbled, sure>
One day he did not look very well, He was swimming strangely and
appeared to be excreting tons of white flaky stuff, almost as if his
insides were falling out, or as if he just ate a whole fish or some snails
(which he didn't). There were also what looked like lumps protruding from
his stomach.
<Very likely what you so accurately describe was bits of substrate ingested, egested... normal>
Since I never saw a fish excrete this type or amount (constantly for a couple of hours), I was very alarmed. I was not sure whether to remove him to quarantine or wait and see what happens. I decided to wait, and wanted to see if he still had his appetite. He would not eat right away, but after some time, he did eat the seaweed sheet that was in the clip. The next day he was back to normal. This is very confusing. Have you ever seen or heard of anything like that? Could the flowerpot coral have gotten him sick if he did eat some?
<Could be the Goniopora involved... in the wild acanthurids consume, defecate surprisingly large amounts of material. Perhaps give the Surgeonfish sections and FAQs a read on WetWebMedia.com for other input. Bob Fenner>
Thanks in advance for your always helpful advice! Laura

Zebrasoma Wars
Hello again,
I have a 215 mixed fish, invert with 300 lbs of live rock. I purchased a
purple tang which, when acclimated started to bully my pacific Sailfin
tang. (which was already there 3 weeks) The following week, the bullying
stopped and I purchased an Indian Ocean Sailfin (Dej. tang). Immediately, the Pacific started to bully it severely, and the purple is no longer involved.
Will this behavior stop. What should I do at this point?
<Only time will/can tell... Best to not house similar-appearing Surgeonfishes together. Please read here: http://www.wetwebmedia.com/zebrasom.htm>
If I get anther
Sailfin, will they school and stop the madness? 
<Likely make it worse... please reconsider this>
Also regarding water prep, how long should I wait before I can add newly mixed salt/RO water to my system and why cant I do it immediately after the salinity is right. How large of a factor is the air condition in the room where salt is being mixed?
<Please read here: http://www.wetwebmedia.com/water4maruse.htm and the FAQs beyond>
IE, can gas fumes, paint fumes, etc, contaminate if mixing is done in a
garage and left with a powerhead for a few days. I have some stored paint and various other chemicals that one may store in a garage so there are
definitely various air pollutants in there. How much of a factor is this?
<Not much in actual practice... considering the alternate of the exposure of the water surface, entrained air inside the houses, offices of the world. Bob Fenner>

Killer Sailfin (& Cleaner Shrimp f')
Hi Bob, how do I get my Sailfin Tang to stop attacking, my cleaner shrimp. Got the shrimp today at 12:00 pm, all of the antennas picked off by 5:00pm. 
<Put in more rock, hiding spaces for the shrimp and/or remove the Tang from its presence otherwise for a few days. The Sailfin is very likely only trying to "get the shrimps attention" for cleaning services... and the shrimp "suffering from jet-lag". It just needs a rest>
Also, I noticed that they get wobbly after there antennas are gone, (fourth one he has killed). What purpose do the antennas serve, is it balance by any chance.
<At the base of the antennae there are spatial orientation sensors... but not the antennae themselves... These will "regenerate" next molt BTW. Just save it from dying from exhaustion, being knocked about for now. Bob Fenner>
Thanks for all the great resources.

Stocking A New Tank! (Pt.2)
Sorry last question,
<Never a problem!>
In your opinion with a 200 gallon tank is there any chance I might be ok with a purple tang and a yellow tang.  Is one easier to care for than the other. Thanks
<Well, it is possible to keep both together in a large enough tank. Is it advisable? Well, that's a judgment call... Mixing two tangs of the same genus is potentially problematic. The Purple Tang has a more "belligerent" personality, if you will. It can, however, be done. The key is introduction. There are two ways to do this, IMO: Number one, you can introduce two juveniles at the same time, and provide lots of room and rockwork to break up the territories. If one of the fish is larger than the other, it should be the Yellow, IMO. Number two, you can introduce the Yellow Tang first, then introduce the Purple shortly afterwards. Regardless of which approach you take, things can still go wrong! One of the fish can dominate, and possibly kill, the other. Tangs demand a lot of space, and need good food and stable tank conditions in order to live long, happy lives. Please use your best judgment when trying this approach. Good luck! Regards, Scott F.>

Mixing Tangs
I HAVE A 55 GALLON SALT WATER REEF TANK, AND I WAS WONDERING CAN I PUT A BROWN TANG (Z. scopas) INTO MY SYSTEM WHEN I ALREADY HAVE A YELLOW TANG IN IT NOW. LE ROY
<it is possible but not recommended, my friend. Mixing two tangs from the same genus is always risky. The 55 is barely big enough to house one of them as an adult for their territorial nature. I would not advise putting any other tangs in this tank but you may be able in larger aquarium. Best regards, Anthony>

Purple Tang Bully
Thank you for the advice on placing my flame wrasse.  He was starting to pale out and smash his head in the QT tank so after a week, no signs of disease I gave him a dip and placed him in my 55 gallon.
<Ah, good>
His color is very good now, but my purple tang has become aggressive.  He used to live peacefully with my
maroon clown, but now he is mad and is nipping clown and wrasse.  For the first few days the wrasse would barely come out and when he did the purple would chase him back in to hiding.  He seems to hold his own a little more
now, it has been five days.  But there is a little nip out of the flame's top fin and both little bottom front fins on the clown are about half the size they were.  I never see the aggression towards the clown, maybe it happens at night, but it is obvious the purple doesn't like the wrasse.  I thought the clown was being nipped by a big white-spotted scarlet reef crab, so I removed the crab, but the nips I see are new.  Other inhabitants are 6 tiny hermits, about 1/2 inch, 1 cleaner shrimp, 1 brittle star, and 2 feather dusters, all of which are not bothered by the purple tang.  My question is whether this aggression will continue, it has been five days and it seems a little better but there is physical damage, though minor, to the fins of the other 2 fish.  The tang of course looks better than ever.  Also the clown doesn't seem to care that the tang has nipped its fins, it still swims right next to the tang following it around like it always has.  I have 5 little green Chromis, and 3 neon gobies in QT right now with about a week left, I was hoping that adding these might reduce the tang's aggressiveness, will it?
<I would try removing the Purple Tang (to the quarantine tank) for about five days or so... this move, isolation will often quiet down a natural bully>
I wasn't planning on adding any more fish to the tank after that.  But I do have another question about a blenny I saw in a display tank at an LFS.  They called it a yellow or gold Sailfin blenny from Tonga.  They said it was pretty rare and there was a long waiting list for it.  They didn't know the scientific name for it and I looked through all the blenny stuff on your web site and haven't seen this particular one.  It is one of the cutest fish I have ever seen, looking very cartoonish, very big eyes and flat forehead.  It has a fatter and shorter body style than most of the blennies and looks the most similar to what they call a black Sailfin blenny on ffexpress, except it was a very bright true yellow.  Do you have any idea what genus this blenny is in so I could research it more, and you know what it is, is it a good fish for an aquarium or not, also would it mix with the other fish I have, if I was to ever get one with the long waiting  list.
<This fish might well get along with what you have if the system is large enough. Please see here: http://www.wetwebmedia.com/sabertoothblens.htm
What you have seen is likely Meiacanthus ovalauensis>
Thank you so much for the wonderful advice in the past, it has saved my fish. Kylee
<Glad to have helped you help your livestock. Bob Fenner>

We were Sailing along...
<Hi Cheryl, PF here tonight>
I have a Desjardini Sailfin tang that I have had for 4-6 weeks. I am getting another today because I never got the color that I wanted the first time.( I wanted more blue color) I do not have another tank, except a empty 5 gal. with no filter it died).  Can I put a plastic storage bin (I has holes in it that water can go through (10"* 7"*4" or one 12"*8"*5") ) in my existing tank and put my Sailfin tang in it and then add the new tang to the tank? <Well, I would advise that you head out and get a cheapie 10g and quarantine your new fish in there for 4 weeks before adding it to your main display. Here's the link to the FAQ on QT's: www.wetwebmedia.com/quaranti.htm  > I will take the old Sailfin tang to a fish store, but I want to make sure the new tang is doing ok. So I wanted to keep them in the same tank for 3 days. <The problem there is tangs don't usually get along with conspecifics unless you have a very large system. Plus, your new comer could introduce diseases into your tank. Just not worth the risk in my opinion. > Will that work with the plastic storage bin? I have a hang on tank containment tank but that is so small  (7"*5"*4') Or......can small (3") Sailfin tangs get along in the same tank for a week or so?
Thanks,
Cheryl
<You're welcome Cheryl, please read through the QT FAQ and don't mix them together, the money spent on making sure your new fish is healthy will be money well spent.>

Sailfin tang eating cleaner shrimp
Please help!  My sailfin tang who I have had for 1 year has started eating my cleaner shrimp.  She starts by picking on them eventually killing them.  This last time I put in 2 cleaner shrimp at a time thinking it might make a difference, well it didn't.  They are both badly picked on.  I tried giving her more seaweed/algae thinking that might help, but it hasn't.    Please help,  I love to keep cleaner shrimp in my tank!!!
  Thanks for your help.
<Some fishes, including Tangs do become incorrigible in this regard. Sorry to state but there is nothing to be done to change this behavior. Trade the Tang in, or get another tang to keep the shrimp in. Bob Fenner>

Asfur Beat up by Purple Tang
Hi Crew,
<Mike>
How's everybody in the wet world? My tank is 8x2x2 has been running for 4 months So far 80lbs of liverocks whooo it ain't a joke trying to fill this up.
Tank is running excellent current inhabitants: 1 Ocellaris, 5 Green Chromis, 1 Purple firefish, 1 Coral Banded Shrimp, 1 Lawnmower Blenny and my Current addition from the QT the pit-bull Purple Tang!!
<Yikes, a new breed!>
He's been in the main tank for a week. And I purchased an Asfur that's been in the store for 4 Months 4 inches adult coloration. When I released him in the main tank I didn't bother to QT as I've been watching this guy for quite sometime co'z no money = ) He went straight in to the Purple Tangs hang out place inside the big shipwreck when I turned the lights on he has so much scratches on the body with a long slice on the right side and a deep dent. My jaws just dropped Pomacanthus got his butt whoop by tang what is going on??
<The tang is bigger, badder, was there first...>
He ate like crazy and the purple tang was still jerky every time he goes inside the shipwreck freaking shipwreck last night I wanted to throw it away. He is swimming around with pit-bull watching every moves. After I fed them I turned off the lights and went to bed thinking about my beautiful asfur. The next day I sat by the tank turned on the lights he was swimming and the tang seems to calm down except wherever the asfur goes the tang just keeps on following him and swimming closely to the rockwork. My question is I am worried about this scratches and the dent on my asfur's body will this be permanent or scar?
<Likely not>
I am watching with fingers cross that he doesn't get a infection what are my chances?
<Pretty good... large tank, otherwise healthy specimen... very likely tank bred, reared... so low stress>
He is breathing normally. I just need to hear it from you guys. for peace of mind if I lose him my wife would definitely kill me please I need your expertise what should I do?. Thank you again more power to WETWEBMEDIA!!! Regards to all Aquarists!!

Purple tang
I have read through your faq's on purple tangs and I found one that relates to my problem, but I have a few other questions. I recently moved my purple tang from qt to my 55 gallon. His other tankmates were a blue damsel, lemon damsel, yellowtail blue damsel and a gold striped maroon clown. My question is that today I noticed my clown on the bottom of the tank with all of his fins chewed badly. From what I have read, it was probably the tang. My question is that I have the clown in the qt tank now so that his fins can heal but will I ever be able to reintroduce him into the tank or will he just get beat up again?
<In this size, shape, kind system, very likely it will never get along with this Tang>
Also, would adding an anemone help him when I add him back in? The 55 is soon to be a 135 gallon in a few months, so would I have a better chance of just keeping the clown in qt until the move?
Thanks for all of you help,  Deanna
<I would wait on all till you have the larger system... then place the tang in a floating colander of size (plastic, for draining pasta normally) and keep it there, separated from the Clown for a week or so... and read re anemones...: http://www.wetwebmedia.com/marine/inverts/index.htm  Much to understand, go wrong...  Bob Fenner>

School of Yellow Tangs
I searched and couldn't find an answer so here it goes. I have a 250gal reef tank with a G-2 Skimmer, 8 cubic feet of bio balls, and I change the carbon every other week. The tank has been running well for about two years. The water stays crystal clear and the only losses are attributed to aggression. I have a pair of maroon clowns that chase off anything that comes too close to their anemone. They also lay eggs regularly, but the other fish usually eat the eggs before they hatch or shortly thereafter. I have three purple tangs that swim together and generally don't bother anything non-tang. There is about 120lbs of live rock and a number of LPS corals. Now for my question. I would like to add a school of yellow tangs. I know I need to outnumber the purple tangs, but by how many. I have five on hold at the store and have asked for 2 - 4 more. I now they will mow down a lot of algae, but I am fine feeding them regularly. I just don't want to buy a whole school of yellows and have them get picked off one by one. I tried adding a Desjardin tang that was bigger than the purples, but they cornered him until he died. Thanks for the great site it has been a tremendous help.  Ben 
<Ben, Ben, Ben, you will be creating a time bomb. A 250 gallon tank is not large enough to do what you want. There will be constant fighting between the tangs. Even with just the yellows and no purples, the least dominant yellow will always be picked on till death, then the next least dominant and so on and on. Believe me because about 20 years ago I tried it and I thought it would be neat, but all I ended up with was two yellow tangs out of seven. These were housed in a 240. James (Salty Dog)>

Zebrasoma tangs together
Hi,
I have a 4ft long tank and I was wondering if I could keep a yellow tang and a Sailfin tang together. I have lots of rock ( about 100 pounds) and I plan to get about 40 pounds of live rock. I have an Ocean Clear filter with a 600 gph pump and a Magnum 350 filled with glass rings for the biological activity.  Soon, I am going to get a AquaC remora. The other fish include: 2 damsels, and a Hippo tang. 
<I would not recommend it. By a four foot tank, I'm assuming it is a 90 gallon at most. And, if it is a 55 gallon, it's not a large enough tank for either of the two. I've also posted a link for your info on tang compatibility. http://www.google.com/custom?q=Tang+compatibility&sitesearch=wetwebmedia.com.
Thanks. 
<You're welcome. James (Salty Dog)> 

- Adding Purple Tang -
Hi Bob,
<JasonC here in his stead.>
It is an honor and pleasure.  I need to know, I have a 135-gallon tank (72 L x 18 w x 24 h) with about 250 to 300 pounds of live rock in the back forming a wall. 
<That's a lot of rock... is there any water left in your tank?> 
I will be redoing this tank to add a better sump, pump and take out some of the live rock in the next few months.  I have currently a Blonde Naso and a Hippo tang and they both are about 4". I have a Raccoon Butterfly and Yellow tang and they are about 3" a Fuji devil and a coral beauty and they are about 2". And 12" engineer goby.  This tank does not have any sand. It does have flow (6 maxijets1200) but I will be adding 2 Tunze 6000s, later in the year.  I have a chance to get a 4" purple tang. Can I get away with adding him to my tank? 
<Probably not while that yellow tang is in there.> 
Or am I at my fish limit with this tank? 
<Physically, biologically you could probably fit this fish, but socially you could not. I doubt the yellow tang would tolerate a similar shaped fish.>
Thank you very much in advance for your respond.
<Cheers, J -- > 

- Adding Purple Tang, Follow-up -
JasonC,
Thanks for the very quick response. <My pleasure.>
JasonC even if the purple tangs is larger than the Yellow tang, do you still see a problem? <Yeah... he's still the late commer to the party...> I am more worry about the Naso tang than the Yellow tang. <Could also be a problem just due to territory issues, but... typical tang aggression is with same shape tangs.>
By the way on the live rock. How much should I have in my tank 150 lbs, 200 lbs. <Yeah... wouldn't do much more than that.>
Thanks for all the advise and the great help you all offer to us. Your site and all of you people expertise is a very value tool for all of us in the hobby.
Thank you and keep up the good work.
Carlos
