I have a clown thats jaw seems to be stuck open. He is breathing heavily and has been this way for the past few weeks. I moved him over to my HT and treated with Kanaplex and Metro just in case there was some bacterial issue. In the beginning was eating fine but I havent actually seen him eat in over a week. Started after I moved my tank so thought it was stress at first. But still has not gone away. Swims around seems to bump into things so not sure if trying to close his mouth or not. Any ideas on what else I can do?
