Can someone plsssss give me a name for this. This is huge. 6"x 3" and this rock is covered with them. I've had it for some time and it has grown thick and full. The Rock is so full I have trouble placing it some where without sitting it on some ployp.

It's definitely a type of zoas. Maybe mean green?

100% a species of Zoanthid, too many for me to know an exact species name. Someone may know it's hype name though.
