I'll throw out distichopora as an option too, though it's not really growing like you'd expect (except for the color). Anacropora is probably the most likely. Quick google turns up this, which looks pretty close:
I believe that’s an orange montipora setosa. Could be an habanero anacropora but what is difficult to tell because of the distance the picture was taken at, is the size of the coralite & they look too small to be of an anacropora.
