ive got a 55g that im considering converting to a monster fish tank. im not sure what to get for it so i figured that maybe here i could find some good advice. id prefer something that stays under 10inches so that the fish can be comfortable in its home. im open to all suggestions EXEPT: red tail cats, arowana, jags, FHs, and any other fish that will eventually get to big because i have NO INTENTIONS of buying a larger tank.
