What is this?

Im pretty sure its an LPS as its polyps kind of look like little black tentacles. Picked it up from the LFS fir 30 dollars cause it looked really cool. Maybe looks like a platygyra? Just not really sure. Greenish-teal in the trenches, bright green ridges and black tentacle-like polyps, really couldnt pass up on such a dope coral, but I want to make sure it gets good care so it thrives.

Try some top down pics and in whiter light. Also, does it puff up a lot? Where are the tentacles located when they show up? All over, around a disc?

Probably a hydnophora.
