Chris 777,
I think your confusing the Pink Margin Fairy with a Red Margin......actually that I know of there is no such thing as a Red Margin.
The Pink Margin is a Cirrhilabrus Rubrimarginatus and it's common name is a Pink Margin fairy. I would imagine that some dealers will call it a Red-Margin because the fish has a red trim strip on the tip of it's tail. But the true name is Pink - Margin and that's the fish that is pictured in my gallery and should also be listed at the begining of this thread.
The solar fairy male has a turqouise-blue body with a red and yellow head. A dead give away of the male besides the turqouise body is the black trim shading around the gill cover. However, this species of fairy is a VERY VERY close cousin to the aurantidorsalis (Orange-Back fairy) and the leutovittatus (Goldbar or Yellow-band fairy). It's thought that there may even be some inter-breeding going on and that is why Solar fairy males are highly variable in color.....even for the males. For example, males from the Flores and Banda seas take on a dark red-orange-purple body instead of the turqouise blue that is most commonly seen in the trade.
In any case the females tend to look the following way: The head is a dark cranberry-purple-magenta and that color fades into a yellow back half of the body. Alot of times some LFS will label females as Ruby head fairy or Purple Parrot Fairy wrasses.......when in all likelyhood it's a female solar.
Chris I'd like to suggest that you purchase Rudie Kuiter's book on Rainbow and Fairy wrasses and you'll get all the pictures you want that will break each fairy down by male and female and juvenile.
The pictures in that book will portray the fish better than I can describe it here.
