whats the dimensions of the 60gal... I would say its more about the dimensions than the 10-15 gallon differnce.... just cause he is so long, about 12 inches full grown.... so, in a 12 inch wide tank (55gal) it wouldnt be too suitable I think.
Honestly I have never kept them, but they're something I always wanted... they just look pretty hardcore with those sharp teeth showing. might take a couple junks out of those pretty angel fish fins though.
