SPS Help exposed skeleton

[Ryan]

When I noticed it it was green. I have some other skeletons in there that look exactly like that bare patch. I didnt notice this die off until those other skeletons were introduced.

Many times green skeletons can signal phosphate issues, latent or otherwise present in the water column.

This does look like a coral had stung it. But the necrosis has stopped. There is no white edging of the coral tissue, so you are in the clear. As you said, the polyps are out.. which is a very good sign.

I won't worry about the coral. Just give it time, and it will recrust over the exposed skeleton.
