Thanks zfunk, this was exactly what my train of thaught was with regards to reponsibly keeping the ABT. It being one of the smaller tangs and notably a peacefull fish, I think would be an exelant candidate for my 75. Of course to be moved to a larger tank weather it be an upgrade on my part(inevitable anyway in this hobby) or a move of sorts elsewhere(big tank)
QUOTE Zfunk: Also, I think there is a double standard with tangs, I bet there are 1000's of people on this site that have yellow tangs in 75 gallon tanks or less, despite the fact that even they grow to around 8" which is far to big for a tank that size. As well as sailfin tangs which reach 16", sohal tangs which reach 16", Naso Tangs which reach 18" and the list goes on and on.
So in conclusion i'd have to say that putting a small Atlantic Blue Tang in a 75 gallon aquarium would be comparable to putting a small yellow tang in one. Which I KNOW for a fact quite a few people on this website have done. Probably even people posting in this forum. So lets all ease up a bit shall we? And stay on topic.
Couldnt agree more with you on that one!
Jeffie, thank you very muchfor your input and the heads up on the deworming. However I need to make an observation, in my experience fish are more likely to QUICKLY grow to their potential in a larger display. Which could explain your observations in your set up, which is a REALY huge set up. At 6 years they are 8" you say. So how long did it take them to get to say 5"? I agree that the kole might be better due to its smaller size however even it will require an upgrade to bigger tank eventualy.
My thaughts on this is I would personaly want to move the ABT to a larger tank when it got to 5 or 6". My guess would be that I would have close to 2 years till that time.
LanT the plan would obviously be to get a small one. Surely you do the same when you buy a fish for your 29

BTW I disagree, not all tangs behave the same, not drasticaly different however different(20 years is a long time to stare at fish) Surely some day when you fill up your 240 and get to stare at tangs for long periods of time youll agree wholeheartedly.
Anemicoak, thank you for bringing that in. Surely Scott Micheal has lots of experience, I havent heard of him, however logicaly he saw the ABT as one of the smaler tang specimens tat could probably bare with a tank that small, however I dont think any tang could REALY be happy long term in a 75. Surely the consensus on keeping fish has changed in favor of the fish over the years. When was the book writen?
Thank you for clearing that up AJP
