What is growing under my Zoa's?

[GJak]

There is a large white mass growing underneath one of my zoa clusters. All the polyps on that cluster have looked like they are being destroyed for the past few days. They finally shrank to the point where a large white mass was visible underneath. Can anyone tell me what's going on? All of the other zoas are doing fine. It is just the Pandora's with the white blob that are being affected.
