Looks like critter was picking at it or possibly stung by another coral. Also, sometimes during shipping it can look like that. Anything like that happen u think?

Sun corals are know to be very temperamental. They are NPS. (Non-photosynthetic). They need to be fed. Generally at lights out or when the polyps are out. If it wasn't a tank raised piece the chances of a sun coral surviving are not great. To feed it most people put a Tupperware over them with a couple small holes in it and turkey baste appropriate sized food into the Tupperware. They will leave it covered for an hour or so and make sure that food stays suspended where the sun coral can grab it. They like to pretty much be in the shade with very very light flow.

Not to be a Debbie downer but usually when they look like that (showing skeleton) they are checking out and the chances of getting them turned around is slim.

I have a black sun coral that got zapped by a trumpet coral's sweeper/feeder tentacles and had similar damage after the damaged flesh was blown away.

Getting it away from whatever is damaging it (be it fish or other coral) is a must. Target feeding and good water quality will get it back right. I think feeding was the key for it's turn around. I fed it 1 mysis/brine/etc per head every day. It actually recovered quicker than I thought it would and finally started sprouting new heads from the continual daily feedings after having it do nothing for over 2 years.

Mine is actually on a frag rack upper/mid tank so it doesn't seem to mind the light (only place I could put it without it getting zapped by something else). It is also really close to a return line from the sump so it doesn't seem to mind flow either. hmm.png
