Care

Chromis hanui is a hardy species that adapts well to life in captivity. They prefer an aquarium with plenty of live rock for hiding and swimming space. A peaceful community tank is ideal, as they are less aggressive than some other damselfish species. They thrive in stable water conditions and benefit from a varied diet of meaty foods and high-quality marine flake or pellet food.

Reproduction

Like many damselfish, Chromis hanui are oviparous, with distinct pairing during breeding. They lay eggs on a flat surface, which are then guarded by the male until they hatch. Breeding in captivity is possible with the right conditions and a well-established pair.

Habitat

The Sunset Damselfish is native to the Northwestern Hawaiian Islands, particularly around Midway Atoll. They are typically found in shallow, clear waters over coral reefs, where they swim in small groups. Their natural habitat suggests a preference for strong water movement and ample hiding places in the aquarium environment.

Geographical distribution is currently limited to the Northwestern Hawaiian Islands, but as the species becomes more popular in the aquarium trade, it may be found in captive environments worldwide.
