Long ago when I was a kid, I feed my oscars and jack dempseys dry cat food. Mainly the fish flavored type. After spending 12-13 years away from the hobby, I got back into with my son. He had 4x 6-7" pacu, thinking back ,I decided to try cat food again. The pacu ate it, but it seemed to cloud the water. I quit feeding because against fish food it seemed to have more fat and less protien.
I have heard, but don't know for sure, that purina makes a bulk fish food pellet.
