My LFS gave me this dying frag about a month ago, this polyp was a tiny spec of red and now it’s grown, it’s part of a larger dead section seen to the left and above it. I’m looking for an ID. During the day it opens more out and looks like a flat red disc w this green center. There’s another very tiny polyp started but I couldn’t get a good image of it. I see no visible movement on the polyp and no tentacles ever come out that I’ve seen. Any ideas?
