Common name: Tahitian butterflyfish

General information

The Chevron Butterflyfish, scientifically known as Chaetodon trichrous, is a striking species admired for its vibrant coloration and patterns. This species is characterized by its deep-bodied shape and the chevron patterns on its sides, from which it derives its common name. The body is primarily white with yellow accents and black chevron markings, and it has a distinctive black band through the eye.

Chevron Butterflyfish are endemic to the Hawaiian Islands, where they are found in coral-rich areas of lagoons and seaward reefs. They are a popular choice among advanced aquarists due to their beauty and unique appearance.

Care

Caring for Chevron Butterflyfish can be challenging, as they require a well-established aquarium with plenty of live rock for grazing and hiding. They are known to be picky eaters, often preferring live coral polyps and certain invertebrates, which can make them unsuitable for a reef tank with a variety of corals. A varied diet that includes marine algae, mysis shrimp, and other meaty foods can help maintain their health in captivity.

Reproduction

In the wild, Chevron Butterflyfish form monogamous pairs during the breeding season. They are pelagic spawners, releasing their eggs and sperm into the water column where fertilization occurs. The larvae are planktonic, drifting in the currents until they develop into juveniles and settle onto the reef.

Habitat

Chevron Butterflyfish are typically found at depths ranging from 3 to 182 meters (10 to 600 feet), but are most commonly seen between 10 and 60 meters (30 and 200 feet). They prefer areas with strong water movement and abundant coral growth. Their natural range is limited to the Hawaiian Islands, making them a geographically isolated species.
