Look like you got AEFWs.

Make sure you have good flow around the colony. Is this a aquacultured colony or wild? I would also bump the Sal to 1.026. SPS do better. You may also want to frag it so you don't loose it all.

Agreed on the flow, bump it up if you can. Also, have you checked for any bugs or critters crawling on it? Have you changed it's position in the tank?
