Common name: Bannerfish

Heniochus is a genus of butterflyfishes known for their elongated dorsal fins and striking black, white, and yellow coloration. They are popular in the reefkeeping hobby for their elegant appearance and peaceful nature. Heniochus species are generally hardy but require a well-established aquarium with plenty of swimming space and live rock for grazing. They are omnivorous, feeding on a variety of foods including algae, coral polyps, and small invertebrates. It's important to note that some species may nip at corals and clams, so careful selection and observation are necessary when introducing them to a reef tank.
