The correct identification is.......
The fish featured in the picture is Cirrahilibrus lineatus. I was thinking it would be nice to give some background on the fish, when I realized I didn't have much accept to say, they are a fairy wrasse, they are reef safe. When first placed in the tank they are prone to parasitic infestation, so quarantine is a must. Fairy wrasses are a harem fish, the one in the pic is a very good pic of a supermale, in your aquarium this fish would slowly change to female if not surrounded by 1-2 females. They are fairly hardy, take to prepared foods readily, but are very skittish and it is not uncommon for one to go carpet surfing. This fish is very active once acclimated to the tank, but don't expect to see it at all for the first couple of weeks in the tank. All in all a beautiful addition to any reef tank.
