Coral ID please. Cyphastrea, Stylocoeniella, Porites, Montipora, Scroll?

[Stoichiometry]

Got this coral from the LFS and not exactly sure which species. Under lights it looks very dark purple, almost black, with bright yellow polyps that look pretty uniform. I'd like to figure out where to place it in my tank. I guess I can leave it at the bottom for a while to get a better ID

Not a porites or any kind of monti. Polyps are incorrect for those species. Hopefully someone can say if it's cyphastrea or something else. The texture reminds me of cyphastrea.

Here's a 50% orange filter photo after placed in my tank. Tank lighting is pretty blue.

This is where polyp extention will be most helpful. Once setteled in and polyps open. Identification will be much easier.
