I appreciate everyone's input! I haven't kept an Oscar before, although I've always wanted to. Never had a corner tank either, I know the sides are 48, but the hypotenuse is over 5' if my math is correct, so there is more swimming space than a straight 4' tank, right? I like the look of the A. Crass, and the idea of patients interacting with the fish, that's the main reason I don't want to do a reef tank or African cichlids. Hadn't realized synspilums were boring, I haven't kept one of them either.
Just not sure I'd be able to find that type of oscar, so wondering if a regular one would really get too big for that tank?
