The guy I got mine from said it was some weird name I don't even remember but it looks just like the rainbow monti so I don't really know for sure, but that's what I call mine lol.
I am assuming that's a photo from a camera phone so with what I see, I'd say it is a Rainbow Montipora. The Pokerstar has all green polyps I believe and yours looks like the colors of the polyps change a bit like the average Rainbow Monti.
