Not a problem. I used to have a website with the scientific info, but haven't been able to find it for about the last five years when I've searched. I need to reinstall it into my memory, so if I can find the website, I'll post it. I thought it was called a Caribbean Cup Coral, but not getting what I'm looking for with that search. It is similar in form to the Caryophyllidae (Phyllangia sp, maybe?). The skeletons I come up with are colonial, and I'm used to seeing those in singular form.
