Common name: yellowfin chromis

General information

The Blue-green Reef Chromis, Chromis xanthopterygia, is a small and peaceful marine fish that is popular among reef aquarium enthusiasts. This species is known for its striking blue-green coloration and yellow pectoral fins, which add a vibrant splash of color to any aquarium. They are schooling fish in the wild and exhibit this behavior in captivity as well, which can be a captivating sight.

Care

Blue-green Reef Chromis are relatively hardy and can be a good choice for both beginner and advanced aquarists. They thrive in well-established aquariums with stable water conditions and plenty of swimming space. A minimum tank size of 30 gallons is recommended for a small group. They are omnivores and will accept a variety of foods including flakes, pellets, and frozen preparations.

Reproduction

In the home aquarium, Chromis xanthopterygia may spawn if they are kept in a large enough group and the environment is stable. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. Raising the larvae can be challenging due to their small size and specific feeding requirements.

Habitat

Chromis xanthopterygia is found in the Western Pacific, from Indonesia to the Solomon Islands, and north to Japan. They typically inhabit coral reefs and lagoons, often found at depths from just below the surface to about 12 meters. In the wild, they are commonly seen in large aggregations above stony corals and reef slopes.
