H. Mag with lesions on base

[Wtyson254]

My H. mag was stung by my H. malu about three weeks ago, it thought it was ok, but it has started to develope these lesions on its base and near its mouth. It does not gape and has not moved since I put it in it new spot 3 weeks ago.

any thoughts?

FYI, I have three other H. mags in the tank that are doing great.

Can you get some pics in 100% white light? Also, if using a phone to take pics, place phone flat on glass. That will give the clearest possible pic.
