Common name: Blue Axil Chromis

General information

The Blue Axil Chromis, scientifically known as Wrangelia argus, is a small and colorful reef-associated fish that is popular among aquarists for its vibrant blue-green hues and peaceful demeanor. This species is part of the Pomacentridae family, which includes damselfishes and clownfishes. The Blue Axil Chromis is often appreciated for its schooling behavior and can add a dynamic visual element to a reef aquarium.

Care

Blue 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. A diet of high-quality marine flake food, supplemented with frozen or live foods such as brine shrimp or mysis, will help maintain their coloration and health.

Reproduction

In the wild, Blue Axil Chromis are known to spawn in groups, with females releasing eggs that are then fertilized by males. In the aquarium, breeding can occur if the environment is stable and there are multiple individuals to form a breeding group. The eggs are typically laid on a flat surface and guarded by the male until they hatch.

Habitat

Wrangelia argus is found in the Western Pacific, from the Great Barrier Reef to the Solomon Islands. They prefer shallow, coral-rich areas and lagoons, often forming large schools in the wild. In the aquarium, they benefit from a setup that mimics their natural habitat, with live rock formations and ample open water for schooling behavior.
