My Clown fish has started acting very odd. He has been wedging himself between the glass and live rock (I mean really wedged) He just hangs there stuck, will come out for a minute and then go back. He doesn't see to be itching himself, just getting stuck. He also has these odd circles all over him, its not white dots like ich but more of a clear circle. It is mainly on his head and can only be seen on the black stripes. He is still eating daily.....any ideas?
He is an older fish. unfortunately where he wedges himself is really odd so hard to get a pic, I can try tonight though
