I am growing out a Buttikoferi in my 55 gallon at the moment, it is around 3" now. I will be moving it up to my 75 gallon at around 6" I'm thinking. But for the time being I was wondering if there were any good tankmates for the Tilapia, maybe some type of catfish perhaps. I know it's hard to find a fish that will be able to put up with the Butts aggression, but worth a try. Thanks for the suggestions.
