It looks to like one of two things. First ,somthing close is hurting or irritating it.And second it could be getting ready to spawm. Those are my guesses :wink1:,hope it helps.

There is nothing in "close" proximity that will hurt him. The only piece that is closest to him is my trumpet coral. But they have "elbow" room when they open up. I thought these guys spawned by popping round egg lookin things out of their mouth area. Could it be spawning in a different way?

looks more like unhappy tissue that is getting white/bleaching how long has it been in it's present location?
