Snorkeling in the Red Sea, I noticed fish that were near the edge of my purple-range. They were small--perhaps 3-5 inches. Looking at guides I would say they were angelfish or anthias, but surely there are marine biologists who know exactly what these were. I have see other purple fish, these were unusal in that--even in sunlight--they were sometimes nearly obscured by the pigment. Can anyone give a likely identification?
