Genicanthus caudovittatus. This attractive species is rarely available in the trade, yet when so, makes for a colorful and peaceful addition to both fish-only and reef aquariums. The male is quite different in coloration than the female, i.e., sexually dimorphic, as males have a whitish blue body with vertical dark brown bars and a black ban at the central base of the dorsal fin, whereas the female is overall a light lavender grey with a black ban above the eye and a similar ban on the upper and lower margins of the caudal fin. Both have a tail that tapers into the body, resulting in what can be called a swallowtail appearance. In fact, those in this genus are sometimes called Swallowtail Angelfish.
