Sea hare sore

My sea hare appears to have a sunken, festering sore on his side. I tried a chat with saltwater fish and got no good answer so I was told to try the forum. Has anyone seen this b4?

Hi, I'm going to move this to our Reef Forum so hopefully it will get attention. The Disease Forum is exclusive to Fish Diseases.

In the meantime, what type substrate are you using? it looks like it may be rough, maybe even containing crushed coral?
