Common name: Allen's chromis

General information

Allen's Damsel, scientifically known as Chromis alleni, is a small and vibrant member of the Pomacentridae family, which includes damselfishes and clownfishes. This species is named after Gerald R. Allen, a renowned ichthyologist who has described numerous reef fish species. Allen's Damsel is appreciated for its striking blue-green coloration and peaceful demeanor, making it a popular choice among reef aquarium enthusiasts.

Care

Allen's Damselfish are relatively hardy and can adapt to a variety of aquarium conditions, which makes them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with stable water quality and plenty of live rock for hiding and grazing. A varied diet of meaty foods, algae, and high-quality prepared foods will help maintain their color and health.

Reproduction

Like many damselfish, Chromis alleni exhibits a fascinating reproductive behavior. Males prepare and defend nesting sites where females lay their eggs. The male then guards and tends to the eggs until they hatch. In the aquarium, breeding can occur if the environment is stable and the fish are well-fed, but raising the larvae can be challenging.

Habitat

Native to the Western Pacific, Allen's Damselfish can be found in coral-rich areas and lagoons. They prefer shallower waters where they form small groups and are often observed hovering above stony corals or branching corals like Acropora. Their natural range extends from Indonesia to the Philippines and northward to the Ryukyu Islands.
