Common name: convict tang

General information

The Convict Tang, scientifically known as Acanthurus triostegus, is a distinctive and widely recognized reef fish. It is named for its bold black stripes on a white to silver body, resembling the uniform of a convict. This species is part of the surgeonfish family, which are known for the scalpel-like spine on either side of the caudal peduncle, used for defense and territorial disputes.

Convict Tangs are active swimmers and are often seen grazing on algae in the wild. They are a schooling species, which adds to their appeal in a spacious home aquarium setting.

Care

Convict Tangs are relatively hardy and can adapt to a variety of tank conditions. They require a large tank with plenty of swimming space and rockwork to mimic their natural habitat. A diet rich in marine algae and vegetable matter is crucial for their health, and they can also be offered meaty foods occasionally.

Reproduction

In the wild, Convict Tangs spawn in groups with a complex courtship display. In the aquarium, breeding is rare, but environmental conditions such as lighting and water quality can influence their reproductive behavior.

Habitat

Acanthurus triostegus is found in shallow reefs and lagoons across the Indo-Pacific region. They are commonly seen in both pristine and disturbed reef environments, grazing on algae-covered substrates.

Geographical distribution includes areas from East Africa, across the Indian Ocean, to the Ducie Islands, north to southern Japan, south to New Caledonia, and across the Pacific Ocean to the coasts of Central America.
