The Chevron Tang, also known as the Hawaiian Bristletooth, Hawaiian Surgeonfish, or Black Surgeonfish, has an oval body shape with radiating, bold markings that change with maturity. As a juvenile, it is bright orange with violet markings on the body and fins. When mature, the bright markings turn an olive brown color with thin lines on the body.

A 75 gallon or larger aquarium is necessary to provide plenty of swimming room. It is aggressive towards other Tangs and may be harassed by its own species, but is peaceful with other fish and sessile invertebrates. It is best to house only one specimen per tank.

The diet of the Chevron Tang should consist of frozen herbivore rations, dried marine algae, and vegetarian items such as Spirulina, zucchini, broccoli, leaf lettuce, and dried seaweed.
