ID Please...Whats on my Coral

[nrhk]

Hi, I am new to reef tanks. Got a used tank last year. This coral was dipped in Coralx and was doing good. Lately I see the dark spots developing on it. They used to be on the edges, but now it looks spreading.

Please advice.

Turn off, or down the blue lights and try to take the picture again so your phone can actually take a picture with detail. Sorry if this sounds rude......

Def need a better picture to confirm, but it looks like it is receding & is exposed skeleton. What is your light & tank parameters? Flow? Was this a colony in the existing system?

Look up brown jelly disease or brown band disease and see if it looks similar. As others have said, if you can get a better pictures with the blues off it would help tremendously.
