What is this?

I’m sure this is super obvious but can anyone tell me what kind of coral this is? Sorry for the crummy photo, it’s at the LFS and they’ve got it all dark with blue light in there.

Very hard to tell from that picture. I would guess a chalice based upon the skeletal structure wrapping/growing around the base of the frag plug, but that is just a guess. Maybe an a. echinata would be my other guess.
