Keep a close eye on that, and keep us posted.

What fish are you keeping again?
Agreed....I will add, are their any changes in your tank? New lights or bulbs?, new flow?, new livestock? Have you noticed it feeding? It almost looks like it was stung by another coral to me. As SP said I would keep a close eye on it and even throw in some carbon if you don't have any going now.

good luck.........chuck
