The Heniochus Black and White Butterflyfish, also known as Longfin Bannerfish, has a very elongated white dorsal filament. It has a base color of white with two wide black stripes. The soft dorsal and caudal fins are yellow, and there are black marks above the eyes. Members of the Heniochus genera are often called Bannerfish instead of Butterflyfish.
The Heniochus Black and White Butterflyfish may reside in a 50 gallon or larger aquarium with other peaceful fish and others of the same species, if all were introduced into the tank at the same time. When swimming, the elongated white dorsal filament moves like a banner in the wind.
It prefers a diet of small meaty foods and herbivore preparations.
