I noticed today that my ocellaris has some kind of lesion on it. Seems to be doing well despite how bad it looks. Right after I noticed this on my clown this morning I saw a different mark on my Hepatus Tang. I'm not sure if they're related so I included both in the same thread. And now for the Hepatus. Smaller and harder to see but it has a round circle right underneath its smaller black stripe. I'd appreciate any inputs on what these are and what, if anything, should be done about it. Thanks.
