Clown Fish Help

[reefercal]

I have a pair of morph oscellaris. I was away for 2 nights (didn’t feed) and returned to find the larger with some serious mouth injury. Can not tell if this is disease or an injury from fighting. She has been very aggressive to the smaller clown also lately. I put a picture below - can anyone please help identify the issue / recommend a course of action. Any help would be much appreciated!

Images below. The piece hanging out I believe is part of her mouth that looks like it fell off or something.

It does look like an injury. Keep a close eye on it as when things like this happen it can turn into a bacterial infection.

A 30 minute bath in methalyne blue or a 90 minute bath in acriflavine may be beneficial to help prevent infection as they both have antiseptic properties.
