sps ID please
 

Been debating this with a few different people and need to find whom if anyone is right on this id!!
suggestions so far:
-acro efflo
-turbinaria
-montipora undata
Any one agree with any of these or have another idea?
Its the purple piece with the green outer edge right next to the red monti.

def a monti of some sorts

reason being?

cant say for sure but well it doesnt look like an acro effo to me and it could be a turbinaria but it looks more like a purple montipora to me the green rim is interesting though:)

Oops.

It is definitely not a Monti undata. I would need a better photo to ID well. I can't even tell if those are small polyps on the surface...? If those are small polyps it is definitely not Turbinaria sp. It might be A efflo, but I would need to see a better photo. Please try to get a clear macro photo. Either remove it to a photo box or try macro setting and zoom in.

don't really want to remove it, I'll try for a better pic but its at the center of a corner bow front so good pics are hard to come by!!

here's a try at another pic

Hmmm...those little lighter specs on the surface...are those polyps or?

It's either a monti or some type of LPS...is it fleshy to the touch? It definately is not an acro.
