Common name: Black-barred surgeonfish

General information

The Zebra Surgeonfish, scientifically known as Acanthurus polyzona, is a striking marine fish recognized for its distinctive black and white striped pattern, which resembles the stripes of a zebra. This pattern provides it with a form of camouflage known as disruptive coloration, which can confuse predators and prey alike. The species is part of the Acanthuridae family, which includes other popular surgeonfish and tangs known for their utility in controlling algae in reef tanks.

Care

Acanthurus polyzona is a hardy species that adapts well to life in captivity, provided their needs for space and water quality are met. They require a large tank with plenty of swimming room and stable water conditions. These fish are herbivores and thrive on a diet rich in marine algae and vegetable matter. Supplementing their diet with high-quality dried seaweed and algae-based pellets or flakes will help maintain their health and vibrant coloration.

Reproduction

In the wild, Zebra Surgeonfish are known to form spawning aggregations, where they release eggs and sperm into the water column for external fertilization. While breeding them in captivity is challenging, understanding their natural reproductive behaviors can be beneficial for potential breeding programs.

Habitat

Native to the Western Indian Ocean, Acanthurus polyzona can be found in coral-rich areas of lagoons and seaward reefs. They are typically observed at depths ranging from shallow waters to about 30 meters. In the aquarium, replicating their natural environment with live rock structures and ample hiding places can help reduce stress and promote natural behaviors.
