Common name: Chevron Tang
General Information
The Chevron Tang, scientifically known as Ctenochaetus hawaiiensis, is a stunning addition to any saltwater aquarium, especially for those seeking a unique and vibrant fish. This species is known for its striking coloration, which changes dramatically as it matures. Juveniles display a vibrant orange body with blue chevron patterns, while adults develop a more subdued brown coloration with blue highlights. This transition makes the Chevron Tang particularly fascinating for aquarists who enjoy observing the natural progression of their fish.
Native to the Hawaiian Islands and parts of the Central Pacific, the Chevron Tang is a popular choice among hobbyists due to its hardiness and algae-eating habits. These fish contribute to the health of the aquarium by grazing on algae, helping to maintain a clean and balanced environment.

Taxonomy
Care
Chevron Tangs are relatively easy to care for, making them suitable for moderately experienced aquarists. They require a well-established aquarium with plenty of live rock to graze on. A tank of at least 400 liters is recommended to provide ample swimming space and hiding spots. Stable water conditions and a varied diet are essential for their health and longevity.
Diet and Feeding
As herbivores, Chevron Tangs primarily feed on algae in the wild. In captivity, their diet should consist of marine-based algae and seaweed, supplemented with high-quality herbivore flakes and pellets. Offering a variety of foods, including spirulina and nori, can help ensure they receive balanced nutrition. Feeding should occur several times a day in small amounts to mimic their natural grazing behavior.
Behavior and Compatibility
Chevron Tangs are generally peaceful but can exhibit territorial behavior, especially towards other tangs. They are best kept as the only tang in smaller setups or with other non-tang species in larger tanks. Providing plenty of hiding spots and visual barriers can help reduce territorial aggression.
They are reef-safe, making them compatible with a wide range of invertebrates and corals. However, they should not be housed with overly aggressive species that may bully them.
Health and Common Issues
Chevron Tangs are hardy fish but can be susceptible to marine ich and other common diseases if water quality is not maintained. Regular monitoring of water parameters and maintaining a clean environment are crucial. Quarantining new additions and providing a stress-free environment can help prevent illness.
Habitat
In the wild, Chevron Tangs inhabit coral reefs and rocky areas where they can graze on algae. They are typically found at depths ranging from 3 to 30 meters (10 to 100 feet). Their natural habitat includes the Hawaiian Islands and other parts of the Central Pacific, where they thrive in warm, tropical waters with plenty of algae-covered surfaces to feed on.
