I feel horrible about this but i was netting one of my Blue Angels and I pressed the net up against the fish with too much force and probably damaged his swim bladder. The fish lays on the bottom of the tank alot and only swims when there is food in the tank. I'm not sure how much he is suffering but I'm afraid he won't be able to defend himself as some of the other Angels get bigger. Is there a chance that this will heal on its own or have I damaged the fish for life? Should I put the fish down or is there still a chance he will recover?
