The Chevron Tang is aggressive towards other tangs but can coexist peacefully with other types of fish. It gets quite large, and needs at least a 180-gallon tank with plenty of room to swim. As a juvenile, this tang is bright orange with violet markings on the body and fins, but it turns olive brown with thin lines, and sometimes almost black as it reaches maturity.
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 180 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. Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a veggie clip , and feed at least 3 times per week. Sea Veggies , Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.
