Wow awesome find Doc. There was a shortage last year because divers couldn't locate them. It is good seeing they are still around.
These were on our last dive of the trip in much shallower water than we had been in earlier in the trip. This was also a big surge area. I don't know for sure but judging by the fact that they were literally everywhere you looked on this dive that they are like that in similar shallow areas on this same reef. Only saw the two colors. Didn't see any of the orange in a colony as big as that green one but they were just as abundant.
