Trachyphyllia radiata

[Matthew Cautero]

My Trachyphyllia radiata is kind of showing its Skeleton on the edge of the coral. What could be causing this. The Coral is not near any rocks where it can rip its flesh off. My levels are all in check. It looks like someone cut a piece of pie out of my coral its a really small spot but its in the shape of a pie on the edge of the coral The only change i made to my tank is bump up my lights but its currently in acclamation mode. Also i have a pretty bad break out of detritus but i dont think thats the problem. Can someone help me lol
