Different species eat different foods, me prefer live fish, some small flakes. If a predator type fish try meaty foods such as frozen or live smaller fish, worms or shrimp. Smaller less aggressive fish try flakes and also smaller worms and shrimp. There are also a wide variety of sticks and pellets for fish.
