ID help please, possible Scoly?

It is a little smaller than a silver dollar, it is beginning to inflate like a Scoly but I am not sure, any thoughts?

Given the skeleton exposed showing there was another polyp to the side, I'm guessing Acanthastrea, possibly A. bowerbanki. I don't think it's a Scolymia - the skeletal structure isn't right.

Thanks for the info! The skeleton was throwing me as well. Pulling up pics of other bowerbanki's, I can see similarities.

If it's A. bowerbanki (or another acanthastrea species), it should sprout a baby soon...which will be a tell-tale sign.

It doesn't look like this is the case, but I've seen several instances where people have fragged up Lobophyllia and A. bowerbanki into single polyps...and sold them as Scolymia. It's hard to tell without seeing a full colony or a skeleton.
