I know that just the min and its not considering the full growth of the fish but then if you use that method all the time then non of us would have vertually any tangs becasue a full grown adult can be over 12 " for even a yellow tang. Also i might add that a sohal to reach it full potienial would have to be over 5 or 6 years or even older. By then if I still had the fish I would be able to have a bigger tank. But thank you for your suggetion I know its a whale of a fish lol.
