Concerning message #19244:

Here is one other related picture that was taken on the same dive in the same area. As you can see these are also in the process of changing colors but both still have the white specks that are common on the red-spotted form. Hope this helps.

Locality: Dive Site - Dunia Kecil off Wajil island, 45 ft, Raja Ampat, Indonesia, Banda Sea, 30 December 2006, Reef. Length: 3-4 cm. Photographer: Mike Krampf.

Cheers,
Mike

Thanks Mike,
This photo certainly shows the white patches very well. From the close-up showing the white patches inside the gill circlet, it seems that they are glands - perhaps storing anti-feedant chemicals? 

Sorry to be choosey, but what I would really like is another photo of the green-spotted one in the mating pair in your first message to see if it has white patches as well. If it doesn't, it will suggest that the ones without white patches - which we identify as N. guttata, and the ones with white patches - which I have considered different, are probably all one species.

Best wishes,
Bill Rudman
