This morning when I fed my tank I saw the Royal Gramma come out for some mysis shrimp and his dorsal fin looked rotted. It doesn't look red or irritated or anything though, the fin is just missing some flesh and I just see bones there. Is this more likely to be actual fin rot or is my cinnamon clown possibly picking on him? He's eating just fine, so I think it's more likely an injury. I'll try to get a pic tomorrow morning at feeding time since that's the only time he comes out.
