Originally i thought it was some dirt from somewhere somehow, but i could t rub it off. It also has two red things on it idk what it is though. (On his chin)

Hi, that appears to be a wound. Could have been from rubing the glass. What size cage is he in>?

40 gallon. And it has gone away now so if it was a wound it healed
