Shriveled up, tips are greyish brown. It isn't mushy yet, but it doesn't look good. About 4 days ago it shed some sort of mucus, which I read is normal, but also read it is supposed to snap back to normal after. What should I be looking for to tell if it's going to come back or not. Every other coral is flourishing in the tank. Only coral I have killed so far is Xenia.
