Anthias are very common in the Red Sea. The males and females are really different despite the fact that the male is a dominant female that changed sex. In this occasion, I managed to snap both a male and a female together, to show the sexual dimorphism between the two. It took a few attempts but I was in a very slow dive with a fellow instructor/photographer and we covered very little ground over the 60 minutes we spent under water.
