Natural History: The Blue Chromis is native to lagoons and reef flats, along with reef faces and slopes. Adults are observed singly or in small groups whereas juveniles are generally in larger groups. This species often forms mixed groups with other Chromis species. This species is generally observed swimming close to the substrate and will disappear within the protection of coral or rock when threatened.
Husbandry: The Blue Reef Chromis is a peaceful damselfish that is best kept singly or in groups of at least 6. It acts as a shoaling dither species on the reef and may actually bring fish-in-hiding out into the open in an aquarium. The metallic blue color of the Blue Reef Chromis will likely enhance after acclimation but will fade if not fed an enriched diet.
Reproduction: This species breeds throughout the year. Males defend a territory and change colors during courtship. Males engage in courtship behavior to attract females, which lay eggs in a nest. The male guards the eggs for several days until they hatch.
