Hi, My bleeding apple scoly have some black slime, probably some weird algea covering the back of the coral and slowly taking over the tissue of the coral. It's kinda weird since I don't have any algea problem in the tank and the reverse apple just beside it is doing fine. And no fish or invert are eating it if it is algea.
Any ideas what it is and the best way to treat it?
