I bought this 3 headed branching euphyllia about a month ago and unfortunately 2 of the heads have been on a steady decline since I purchased them. It is apparent that at least one of the two heads is nearing death or already dead. There was some stringy stuff stuck on its polyp, and as I used a turkey baster to suck it off, the polyps detached with little effort. My question is, should I remove the dead polyps manually? Or will CUC clean it up quickly if I leave it in?
