Usually it eats pellets and krill. I decided to give it a feeder, an African Cichlid hybrid. The cichla is now 6", the feeder was 3". Hit it instantly, and to my surprise, swallowed it whole. There was no tail hanging out the mouth. It was GONE. Then two hours later, it was time to feed the cichlids. It ate 3 large pieces of shrimp too. This Cichla is truly monster. I might feed it more often as it can definitely handle more food. I'll work on some update pics.
