Hey guys, I’ve got 4 quarter sized angelfish. When I feed them 3 of them go into a frenzy and are happy, healthy fish. The fourth one doesn’t eat. I even dropped a bloodworm directly in front of him while the other 3 were distracted and he just ignored it. I see him pick and nibble off the wood pieces in the tank but he doesn’t respond to actual food. He’s the little black one.
