General information
The Chromis alpha is a species of damselfish that is not as widely known in the aquarium trade as its relatives, but it is gaining attention for its striking appearance and schooling behavior. This species is characterized by its vibrant blue coloration and a distinctive black spot at the base of the pectoral fin. They are relatively small, peaceful fish that can add dynamic movement and color to a reef aquarium.

Care
Chromis alpha are hardy and adaptable, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with stable water conditions and plenty of swimming space. These fish prefer to be kept in groups, as they naturally form schools in the wild. A varied diet of meaty foods and high-quality marine flake or pellet food will help maintain their color and health.
Reproduction
Like many damselfish, Chromis alpha are oviparous, with females laying eggs that are then fertilized by the male. The male typically guards the nest until the eggs hatch. In the aquarium, breeding Chromis alpha can be challenging due to their need for pristine water conditions during the larval stage.
Habitat
Chromis alpha is found in the Western Pacific, particularly around the Coral Sea. They inhabit coral-rich areas and lagoons, often seen at depths ranging from 2 to 30 meters. In the aquarium, replicating their natural environment with live rock and ample hiding places can help promote natural behaviors and reduce stress.
