Taken in Ambon, Moluccas. They were just feet apart so possibly male and female as they have a few similarities e.g. pectoral fins.
Pretty sure they fall into the genus Enneapterygius which is pretty poorly covered on Fishbase. Grubbing around on Google and a small, not too clear pic in the Tropical Pacific fish book, leads me towards Enneapterygius mirabalis - Miracle Triplefin. However, the sources on Google are not ones well known to me.
Great stuff on here. In some trepidation I'll add a couple of my own - a wide angle of bumphead parrotfish and a macro of a prickly leatherjacket. Never seen the latter before and I think he is pretty photogenic.
I think this is an Oxycheilinus of some sort, maybe O. orientalis, the Oriental Maori Wrasse. I sent a photo similar yours with the green spots to Fishbase a couple of years ago, suggesting it might be a juvenile O. orientalis. They got Dr Randall to look at it. He said he had no records of wrasse like this. I have seen similar ones since so would also be interested to hear from anybody who has any ideas.
If it is like the old Substrobe - and it is the same outer casing - pull out the ready-light lens on the rear with a pair of pincers. It is a conical shaped thing that is a tight fit down a hole and sits on an 0-ring. Use compressed air to then blow out the lens - it doesn't need much and I used a car tyre pump.
