This would be something I would seek out one of the vets about. I've never seen anything like it to where the center will evacuate across the shared wall in a favite or across those in a favia.
Vet? Suggestions on who to ask? Also, as I was cleaning the glass with a soft toothbrush I accidentally brushed this coral and the green just came right off in that spot. It looked like it was not even physically attached. Like the slime on the coral piece was all that was holding it there. The red parts looks fine still. It is even spreading onto the rock.
