I have a pair of black occ Clownfish that have been healthy eaters etc... as of recently the two have gotten into dominance fighting, needless to say one of them sustained decent injuries and now have noticed what looks to be mouth rot. It's extremely hard to get a pic of so I will post a reference picture. The upper lip is completely gone and I can see what looks to be it's teeth, the bottom lip is going now to. It looks like my fish ran into a wall literally and there is blood and white stuff covering his mouth. The other one has backed off but seems to be pushing the injured fish away from the anemone. Im not sure what I'm dealing with here I'm thinking some kind of bacterial infection from fighting?
