Mine had something very similar to this the other day. It went away in about three days.

This would possibly explain mine as I have around 8 or so tuxedo urchins in my tank...although their spines are small. The other culprit could be my bristletooth tang, but those generally are not round lesions.

Doesn’t look like a flatworm but because fox faces lay on the bottom or up against glass when resting or scared, flatworms will sometimes crawl onto them
