Common name: Allen's Cardinalfish

General information

Allen's Cardinalfish (Cheilodipterus alleni) is a small and colorful marine fish that is popular among aquarists for its striking appearance and peaceful demeanor. This species is named after Gerald R. Allen, a renowned ichthyologist who has described many fish species. They are nocturnal and tend to be shy during the day, often hiding among rockwork and corals.

Care

Allen's Cardinalfish are relatively easy to care for, making them suitable for both novice and experienced aquarists. They prefer a well-established aquarium with plenty of hiding places and a peaceful community. They are not aggressive and can be kept with other non-predatory fish. A varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood will help maintain their health and coloration.

Reproduction

Like many cardinalfish, Allen's Cardinalfish are mouthbrooders. The male carries the eggs in his mouth until they hatch, which provides protection from predators. This fascinating reproductive behavior can sometimes be observed in the home aquarium if the environment is stress-free and well-maintained.

Habitat

Allen's Cardinalfish are found in the Western Pacific, from Indonesia to the Great Barrier Reef and the Solomon Islands. They inhabit coral reefs and lagoons, often associating with branching corals where they can seek refuge. In the wild, they are typically found at depths ranging from shallow waters to about 30 meters.
