Anyone have any problems putting a 4 inch atf in the same tank as a 4 inch payara? Right now I got a cheap lil 3-4 inch bala shark in there with the atf and they swimm around togather a lot seem to get along good. In the other tank with the payara hes in with 7 inch clown knife 8 inch bicher 5 inch blue whale I think it was called and a african butterfly fish. Want to put the payara in with the atf tank so I can get the other fish in the payara tank to stop eating feeder fish, they can go through 25 small in one night! The only one I want to eat them is the payara.
