Masked Bannerfish

Overview

The Masked Bannerfish is a distinctive butterflyfish recognized by its compressed, triangular body and a prominent bony protuberance on its forehead. It is widely distributed across the tropical Indo-Pacific, where it inhabits lagoon and seaward reefs with abundant coral growth.

Appearance

This species features a white body marked by three vertical black bands. The first band covers the face, including the eyes and mouth, while the second is a broad bar crossing the mid-body. A third, fainter band appears toward the rear. The dorsal, caudal, and anal fins are primarily yellow, and the first dorsal rays extend into a white, yellow-edged filament. Adults are easily identified by the bony "horn" or growth on their forehead, which is less pronounced in juveniles.

Biology & behavior

Masked Bannerfish are typically found alone, in pairs, or in small groups. While they are generally peaceful, they may occasionally be observed hovering near tabular corals. They are oviparous and are known to form pairs during their breeding cycle.

Feeding

This fish is an opportunistic feeder that consumes various bottom-dwelling animals. Its natural diet primarily consists of small invertebrates found within algal zones and on the reef substrate.
