thanks! I'll get a better pic next time I turn flow off.Hmm, still a little hard to determine for 9. but judging from the shape its frag, it looks like a encrusting sps. Unless if you could lift the coral up and take a pic of it close to the surface, I can’t say for sure. Still most probably a stylocoeniella or bernardpora as the polyps look a little too big to be a porites or monti.
