Tang X 10 / 125

8 feet tall! Very nice. Thanks for sharing. I do agree a 125 is a bit crampy for this but I figured I'd used that size as a minimum and others would chime in with their size tanks and amount of tangs in their groups.

I seriously doubt I would ever setup a tank with a bunch of Yellow tangs but hey, there's always the lotto.
 
a tank with 10 of the same fish (even worse, yellow tangs, IMO), would be a pretty boring tank anyway. that's probably another reason no one has tried it.
 
well...it is personal preference...some people do like a school of Yellow Tang schooling. however, when they start fighting then it's not fun watching them fight violently.
 
Are you thinking it would be like those crowded angel tanks where no one has room to really define a territory, therefore there isn't that much overt aggression? (What do they call those, locker tanks or something?) Seems like it would be stressful and unhealthy in the long run.
 
I know a LFS that did that with Yellow Tangs. They got in 50+ of them and put them in a 125g. They were small when they started, but over time, as people bought them, they thinned out and grew larger.

The 'overstocking' method is something used with african cichlids (heck, all cichlids) as well. Too many fish = diffused territories. Ive seen the same done with dottybacks. A guy near me put over a dozen in a 210g, and because there were so many, none established 'their own' area.

The only downside is that if there are any 'runts', they may not have a chance to compete at all because the status quo prevents them from blending in as well. This was often true when I raised africans/bred them. I would keep a whole breeding colony, and that one small male or female that couldnt put on weight like the others would get picked off eventually.
 
I hadn't thought of cichlids - now that you mention it, I know just what you mean.
 
I think that a tank full of yellow tangs would look spectacular but I could not see myself dishing out the dough for the hardware just to have a school of yellow tangs. But - if I hit the lotto - watch out!

As a person who has kept a few colonies of Tropheus (very aggressive cichlids) I can say that the more the better off the colony will be. So I thought that the same could be done with yellow tangs and that's why I was thinking there would be folks that have tried it and would chime in.

I'm glad we have passed the textbook answers - I mean - I can read too LOL
 
I've seen 30+ purple tangs in a fish store with a flat maybe 16" tall tank, but was like 6'x6'.Supposedly 500 gallons so maybe it was 18" deep. They were all like silver dollars or smaller. Again, it was pretty cool. I bet you could do 10 in a 125 with the right rockwork and flow, but they will get too big in 6 months I'd bet.
 
That is a very bad idea. Are these the only fish taht you are keeping? Tangs can be territorial, and that is way too many for that small a space.
 
You might get away with 3, which still would nice.. I think someone here has a 700pluss gallons with 10 purple tangs or they did...?? Sorry can't remember who it was but i think he had to cut his numbers down because of aggression. (Don't quote me on this)
 
I'd think this would work as long as the parameters were kept in check. I mean tangs can be nasty but we're not talking about a tank with 10 undulate triggers.... now that would turn out interesting....

When yellow tangs are for sale they are usually like 10 in a tank and I never witness homicidal behavior like some of you claim would surface...

BTW, the largest yellow tang I've seen is a foot, he was for sale at my lfs. The guy said he ordered a medium yellow tang and that's what he got.
 
everything I've read says that 1 yellow tang needs a 100 gallon or larger aquarium. Unfortunately, I read after I did my tank. I only have 1 yellow tang in my 75 though and he seems to be doing well. To answer the question though, all of the tanks I've seen with 5+ tangs in them there were always about half of the tangs with bad fin damage. To each his own I guess.
 
My brother has 7 tangs in his 400G tank but they are not all yellow. He has 3 yellows, 1 Powder Blue, 1 Powder Brown, 1 Sailfin, and I think a Atlantic Blue but Im not too sure about the last one (its new and I have never seen it yet). I guess he started the tank with the three yellows and they did not get along at all until he added all the other fish to the tank. Not just the other tangs but also a stars and stripes puffer, harlequin tusk, dragon wrasse, some kind of angel (dont know name) and a few other smaller fish...Anyways, my point is that they fought when they were just focused on each other and stopped once there were lots of other fish in the tank. Might be the same with a bunch in a 125G but who knows???

I know my LFS has had a whole ton of them (maybe 20) for sale in a 130G tank for well over a week now and I was there today and saw no nipped fins or stress really. They would chase each other occasionally but nothing to worry about. Pretty cool looking tank even though they are all just for sale.
 
I appreciate the level of honesty some of you have even though I can see some strain and a dyre hold on to textbook answers. LOL

IMO I think any tangs yellow or other will do well together if kept in large numbers. You almost garantee yourself that one fish will not be able to become king and kill all fish. Things like feeding and parameters are basic and fundamental and should be practiced in any tank regardless.

As for what size tank - I think this is meted out by filtration and aquascaping.

I am well aware of the LFS that keep Tangs by tens and twenties in one tank, in fact, that is what got my attention on this sort of setup and then I began to notice this kind of display in certain movies. They do really well under these circumstances but they are only there for a short period of time and so the question remains can that sort of harmony remain for longer than a month.
 
Yeah, have you seen how they 'flock together' in the wild? The Atlanta Aquarium's Reef exhibit is a good example as well... hundreds of them all huddle up at the surface.

I think as long as you do it like cichlids, you will be fine.
 
if you look on japanese system and reef tank you will see on some of them more then 30 fish in120 gallon and also a lot of tangs .

here it's old photo on 300 gallon tank with 60 fish (if i remember correct...)

unless my crazy Rock beauty all live in peace :D
 
I was just talking to my brother and that Atlantic Blue Tang was actually his 8th tang. I missed the Pacific Blue...He apparently plans on one of two more tangs for his tank eventually if all goes well. He shares your exact opinion that they are fine if they are in bigger numbers. That angel he had though was a Regel and got bullied by some of the Yellow Tangs enough that he had to give it away. Maybe the tangs get even more aggressive towards other tankmates?
