The Chevron Tang (Ctenochaetus hawaiiensis), also known as the Hawaiian bristletooth or hawaiian kole tang, is a species of marine ray-finned fish belonging to the family Acanthuridae. It is endemic to the Hawaiian Islands and nearby regions and is popular in the marine aquarium trade.

Physical Description

Juvenile Chevron Tangs are bright orange with V-shaped chevron markings on the body. As they mature, the coloration changes to a darker brownish-olive with fine horizontal stripes and numerous small spots. The dorsal fin has 8 spines and 27-29 soft rays while the anal fin has 3 spines and 24-26 soft rays. This species reaches a maximum total length of 28 cm (11 in).

Distribution and Habitat

The Chevron Tang is found in the central Pacific, primarily around Hawaii, Johnston Atoll, and Christmas Island. It inhabits shallow coral reefs and seaward slopes at depths between 2 and 50 meters.

Diet and Feeding

The Chevron Tang is herbivorous, using its comb-like teeth to graze on detritus, fine filamentous algae, and diatoms. In captivity, it should be offered a varied diet including marine algae, spirulina, and high-quality vegetable-based preparations.

Aquarium Care

The Chevron Tang requires a well-established aquarium of at least 125 gallons with abundant live rock for grazing. It is semi-aggressive and may display territorial behavior toward other tangs. Generally considered reef-safe.
