I've never been any good with the crazy colloquial names people come up with for coral. I would agree that yes it is probably some sort of acro. It doesn't help that I'm colorblind, so terrible at picking out nuances in colors...what color is it?
I am really bad with IDs as well. When I first seen the picture it looked like some gorgonian to me. Until I seen that you think it might be an acro. Going from softie (gorgonian) to sps (acropora) is not a whole lot of help. So I didn't answer the first time I seen it days ago.
