Thanks for the positive feedback.
I've been feeding him various New Life Spectrum pellets and flakes, Omega One cichlid pellets, freeze-dried shrimp, freeze-dried krill and earthworms.
I'm anxious to see how he develops. I have four additional FH's from the same batch. There is a runt in the group and three colorful, but smaller fish. I'm currently keeping the largest FH by himself. He does not play well with others.
