there are so many green w/ purple rims, it's so tough to tell what's what. Years ago people used to care a lot more about the ACTUAL lineage of corals, now people will call something that has a similar coloration something that it's not. It's a real shame to be honest... Even worse in the zoa community than it is in the SPS one.
Now, having said all that. WOW that's one of the nicest I've ever seen. One of my all time favorite corals, and yours is a stunning representation. Impressed (and a tad jealous).
