Picked this up recently- I want to say Pavona, but I'm conflicted. New growth has a pale lime green color, otherwise its mostly an aqua color, with a navy blue to plum color on the dark areas. Very little polyp extension, no noticeable sweepers at night. Either way, a 2" square frag for $10 was worth it for me- already seeing some growth, and it has gotten better color in the month I've had it.
