Pictures would help. As long as the polyp's head still has tissue on the outer area, that's a good sign. Have you tried running carbon actively through a phosban reactor?

Sorry my parents are in Puerto Rico and took the camera along with them. Like I said, if you were to look at it, it would appear it's fine because it's polyps are fully extended, except the parts of the base where the tissue has receded.

I'm not running carbon right now, but I'm doing regular water changes FWIW.

Without pictures, it's hard to say. I've seen tissue recede after the new polyps have formed. If that is unhealthy, I don't know because I've not seen them in nature. What I've observed over the years is bare skeleton for the base, and tissue on the polyp heads.

Thanks Melev, The heads are still fully extended but the tissue has receded up to the heads. Let's see what happens.

I recently purchased some torch coral frags and while they were in quarantine the tissue was lifting off the trunks. However, after a few days it settled down and the corals looked better.
