My wife has a 70g also and wants a blue tang REALLY bad. We see very contradictory opinions about them for tank size requirements. Some things say 55 others 90. One store here says yes another says no. We would value any real input. The only other bigger fish is a yellow tang. Thank you!!

You could prolly get away with it. It all depends on the dimension of the tank. Tangs are active swimmers so lenght of the tank is more important than volume. Not sure what the dimension of a 70G is but hopefully its at leaset 4' long and not 3'. Does the tank have a fairly open aquascape? That would help make the tang happy too. Like I said, they love to swim. Also current stock plays a role too. If you have a farily low load, it will be ok. I find my current hippo a fairly slow grower. I bought it when it was around an 1" and only has grown another 1" in 1 1/2 years lol. But I hear from others that thiers grow fast. HTH!

I think you'd be ok. Just watch the amount of big fish you put in there. If you put more than 1 or 2, they'll be pissed cause of not enough room. Then they'll fight or get ich from the stress.

I like those tangs too.. where are you going to pick yours up? You can always try to get a smaller one, that might help.

The Paracanthurus hepatus can grow to a foot in length in the wild, though it rarely grows to more then 6 to 8 inches in captivity. As already stated they are active swimmers, if fact they are very active swimmers. We consider them (open water swimmers) which means that they live on (above) the reef not in (among the rocks and corals) the reef. They are known to roam for miles over there natural range and usually fair poorly as they mature in smaller tanks with little or no swimming space. Even in larger tank say like a 180 for instance if it is jam packed with rock like (80% or more) the swimming spaced has been removed compared to a 180 with only (50%) or less rock by volume. Leading specialists also believe that the stress of being in a small tank coupled with poor diet and water quality is a main cause for HLLE.

So simply put, if the fish is large for the tank as an adult (like the tang is for your tank) then it is to large as juvenile, and it really has no business in there. I know that many people do it anyway and most of those fish die which is crazy to me. If you really have to have that fish I recommend that you get a large more appropriate size tank. At least 6 foot, 8 or 10 feet being even better and around or more then 200 gallons.

Thank you. I am not sure where I am getting it from yet. I am still pricing them. If anyone knows of anyone needing to get rid of one let me know :) Thanks.
