Masked Bannerfish

The Masked Bannerfish is a distinctive member of the Heniochus genus, easily identified by the prominent bony protuberance or horn that develops above the eyes in adult specimens, along with a dark mask-like marking across the face. Its body displays the classic Heniochus pattern of bold black and white banding, with the dorsal fin extending into a long, elegant pennant-like filament. Yellow accents on the dorsal and caudal fins add warmth to its striking black-and-white livery.

In the wild, Heniochus monoceros is found on coral-rich reef slopes and drop-offs, where it feeds on coral polyps, small invertebrates, and zooplankton. This dietary preference for coral polyps means it is not suitable for reef aquariums. In captivity, the Masked Bannerfish is moderately hardy and will usually accept a variety of prepared foods, though some specimens may require patience during the initial acclimation period.

This species is peaceful toward other fish and does well in community fish-only systems. It can grow to a respectable 9 inches and needs adequate swimming space and water volume. The Masked Bannerfish is best kept singly or as a mated pair, and should be provided with plenty of live rock structure for shelter and territorial definition. Its dramatic appearance and moderate care requirements make it an appealing choice for aquarists who appreciate the bannerfish group.
