Okay, I have about 2.5 inch blood parrots in the tank with my flowerhorn, he's about 5 inch. But it seems like he hasnt been eating. He crowds around the Parrots and doesnt come up for pellets, he'll only eat live food, and the parrots don't eat. Should I be worrying because he doesn't eat?

he will eat when he is comfortable give it time they will fight for food after awhile

Don't feed him live food. You want him on a pellet. Let him adjust and he will start eating. It took my FH a week to start eating.
