General information

The Hawaiian Wrasse, Coris ballieui, is a vibrant and active fish species that adds both color and dynamism to a saltwater aquarium. Endemic to the Hawaiian Islands, this wrasse is known for its striking orange back and blue-green body, which can make it a centerpiece in any reef tank. Juveniles exhibit different coloration, with white bodies and black stripes, which gradually change as they mature.

Care

Caring for the Hawaiian Wrasse requires a spacious tank with plenty of swimming room and a tightly sealed lid, as wrasses are known jumpers. They thrive in environments with a sandy substrate and numerous hiding places among live rock. This species is generally peaceful but can become territorial, especially towards conspecifics or similar-looking fish. A varied diet of meaty foods, such as mysis shrimp, brine shrimp, and quality marine pellets, will keep them healthy and their colors vibrant.

Reproduction

In the wild, Coris ballieui is a protogynous hermaphrodite, meaning individuals start life as females and can change to males as they mature. In the aquarium, breeding is rare, but providing a stress-free environment with plenty of hiding spaces can encourage natural behaviors.

Habitat

The Hawaiian Wrasse is found exclusively in the Hawaiian archipelago. They prefer reef slopes and lagoon pinnacles, where they can be seen swimming actively during the day. At night, they retreat into crevices or bury themselves in the sand for protection.
