Zebra Angelfish

Overview

The Zebra Angelfish is a marine species native to the western Indian Ocean, ranging from the Red Sea to South Africa and eastward to Indonesia. Unlike many other angelfish, this species is a dedicated zooplanktivore, typically found hovering in the water column above steep reef slopes to feed.

Distribution & habitat

This species is widely distributed across the western Indian Ocean, including the Red Sea, the Maldives, Madagascar, and Mauritius, with records extending to northwestern Sumatra. It is a sedentary, reef-associated fish that prefers steep outer reef slopes where currents provide a steady supply of plankton. While they are often found at depths between 15 and 70 meters, they may inhabit shallower waters in the Red Sea.

Appearance

This species exhibits strong sexual dichromatism, meaning males and females have distinct color patterns. Males are characterized by a whitish-blue body with vertical dark brown bars and a black band along the base of the dorsal fin. Females are generally smaller and pale pinkish-grey, featuring a black band over the eyes and distinct black margins on the lobes of their deeply forked, lyre-shaped tails. Both sexes possess the characteristic preopercular spine common to the Pomacanthidae family.

Biology & behavior

Zebra Angelfish are typically observed in small harems consisting of one male and several females. They are protogynous hermaphrodites, meaning individuals begin life as females and can transition into males. Spawning occurs in the water column, where the pair ascends toward the surface to release gametes for external fertilization, resulting in planktonic eggs and larvae.
