Hello, this is surely a silly question but I am not sure what kind of coral this is. At first look it seems like a dying duncan but it's been like this for over a month, seems to open a bit during the day hours but never any polyps emerge. Tan and light blue skin covering the skeleton and bright green center that doesn't come out. I thought I would double check if I might be missing something.
Thanks for any help.
