Care

Yellow-axil Chromis are hardy and adaptable, making them suitable for both beginner and advanced aquarists. They thrive in well-established aquariums with stable water conditions and plenty of swimming space. These fish prefer to be kept in groups, so a larger tank is necessary to accommodate a small school. They are omnivorous and will accept a variety of foods, including flake, pellet, and frozen preparations.

Reproduction

In the aquarium, Chromis flavipectoralis may spawn if they are kept in a healthy environment. They are egg-layers, with the male typically preparing a flat surface where the female can deposit her eggs. The male then guards and tends to the eggs until they hatch.

Habitat

Yellow-axil Chromis are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and lagoons, often seen at depths ranging from 1 to 12 meters. Their natural environment is characterized by clear waters with abundant coral growth, which provides shelter and feeding opportunities.
