Common name: Yellow-axil chromis

General information

The Yellow-axil Chromis, Chromis xanthochira, is a small and peaceful reef fish known for its vibrant blue-green body and distinctive yellow spot at the base of the pectoral fin. They are a schooling species that adds movement and color to any reef aquarium. These fish are relatively hardy and can be a good choice for both novice and experienced aquarists.

Care

Yellow-axil Chromis are easy to care for and can adapt to a variety of aquarium conditions. They thrive in well-established tanks with stable water quality and plenty of swimming space. A tank with live rock formations for hiding and sleeping is ideal. They are omnivorous and will accept a wide range of foods, including small pellet and flake foods, as well as frozen and live meaty foods.

Reproduction

In the wild, Yellow-axil Chromis spawn over reef substrates, where they lay adhesive eggs that are guarded by the male until they hatch. In the aquarium, breeding can occur if the environment is stable and there are both males and females present. However, raising the fry can be challenging due to their small size and specific feeding requirements.

Habitat

Chromis xanthochira is found in the Western Pacific, from Indonesia to Japan, and south to Australia. They typically inhabit coral reefs and lagoons, often found at depths ranging from the surface to about 12 meters. They prefer areas with strong water movement and are often seen in large aggregations above staghorn corals and other branching corals.
