Got this as a freebie and I'm pretty sure this is an SPS but I'm not sure what it is beyond that. I was thinking a Monti but the polyps seem too close. Perhaps a porite? The frag itself is blue with big holes where the polyps come out. It looks almost like a moon rock when the polyps aren't out (2nd picture).
(Editing here for clarity - the top and bottom are the same coral, one with polyps out, one with polyps in)
