I discovered my largest rainbow was acting odd. He has his mouth open and is flexing it constantly, like he is trying to close it but can't. On the inside, his mouth/throat is bright red and his looks very tense. He won't let any other fish come near. He has been doing this all day.
What exactly is going on with him?
The rainbows pick on each other somewhat, but it never turns violent. Just a nip or two and then they move on. So, maybe he got into a fight? Or maybe he swallow something sharp? None of the other fish are exhibiting any odd behavior. I feel bad, because he attempted to eat with everyone else, but couldn't because he can't close his mouth.
