Black & White Heniochus Butterfly (Heniochus acuminatus) Care
The Black & White Heniochus Butterfly, Heniochus acuminatus, also known as Pennant Coralfish, Longfin Bannerfish, and the Poor Man’s Moorish Idol. These fish come from across the Indo-Pacific region. They have a white body with two wide black bands and yellow dorsal and caudal fins. The leading edge of dorsal extends into a very long white filament. These fish are very similar in appearance to the Moorish Idol, Zanclus cornutus, but are much hardier and easier to keep in a home aquarium than the Moorish Idol.
Butterflyfish are omnivores and require a diet rich in both meaty foods and plant-based foods. They will eat flake food, algae, frozen plankton, and mysis and brine shrimp. They should be fed several times a day.
The Black & White Heniochus can reach lengths of up to 8-1/2″ and will do best in an aquarium of at least 125 gallons with plenty of live rock to graze on and hide in. They will thrive in large fish-only aquariums with lots of open swimming space and live rock hiding places.
The fish are not reef safe and will eat various types of corals.
