Pic is a little too blurry, can't make out the mouths. It looks sort of like an echinata, but again, not clear enough close up to tell.

Cyphastrea maybe?

i was thinking the same. i do have a small collection of various cyphastrea and they all have the same sized polyps or costae; however; this one is different and the polyps or costae is very tiny compared to other cyphastrea.
