Hi, looking for some thoughts about my Goniastrea. It's been in my tank about 3 weeks and yesterday I moved it from the rocks to the frag rack. Only then did I notice this as this side was against the rock and not visible. As you can see its structural base has receded quite a bit. Looks like some sort of decay. The rest of the frag looks pretty decent. Any thoughts? is it a goner or wait and see?
thanks in advance
