don't you think it's hard to argue how much space the blue tang needs to swim?
anybody can have a 5 feet tank but do you think that tang in the 5 feet tank would rather be swimming out in the ocean?
regardless of what anybody may say, the matter of the fact is our fishes are all in captive and i don't know of anything that enjoys being in that. we are all to a certain extent, guilty of wanting a part of the coral reef in our home but i am sure someone else would accuse us of destroying the reef even though polution is the main cause. by the way, how are we going to argue with that?
