Common name: Yellow Axil Chromis

General information

The Yellow Axil Chromis, Chromis abrupta, is a small and peaceful marine fish that is a member of the damselfish family (Pomacentridae). It is known for its striking yellow axil spot located on the upper part of the pectoral fin base, which contrasts with its overall blue to pale green body coloration. This species is not as common in the aquarium trade as other Chromis species, but it can be a delightful addition to a community reef tank.

Care

Yellow Axil Chromis are relatively hardy and can adapt to a variety of tank conditions, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with stable water quality and plenty of swimming space. These fish are schooling by nature and do best in groups, which can reduce aggression and stress. A diet of small meaty foods, high-quality flake, and pellet foods will help maintain their color and health.

Reproduction

Like many damselfish, Yellow Axil Chromis are oviparous, with distinct pairing during breeding. They lay eggs on a flat surface, which are then guarded and aerated by the male until they hatch. Breeding in captivity is possible but not commonly reported due to the species' relative rarity in the hobby.

Habitat

Chromis abrupta is found in the Western Pacific, from the Philippines to northern Australia. They typically inhabit coral-rich areas of lagoons and outer reefs, often found at depths ranging from 2 to 15 meters. In the wild, they form large aggregations above stony corals and are known to retreat into branching corals when threatened.
