what kind of zoa

[Europhyllia]

I think these are some pretty common zoas.
what's their name?
eagle eye?
watermelons?
eye of ra?

I like them. I frag them the lazy way by putting the original rock someplace, waiting till the spread onto surrounding rock and then just pulling up the original rock and moving it some place else.
Wouldn't mind having some more of these though so I need to know their name.
