Hmmm, the color appears off but the growth patten and polyps look like Hydnophora. Can you disturb the polyps, and get a photo with the polyps retracted? Hydnophora has a very distinct skeletal structure, which would be easily recognizable.
agree it looks like a hydno which by the way is considered an SPS by most but who cares...maybe we need a MPS designation ...they're cool corals so long as you keep them away from others so as to not sting.
