Common name: arrowtooth cardinal

General information

Ehrenberg's Cardinalfish, scientifically known as Cheilodipterus lachneri, is a small and colorful marine fish that is a member of the family Apogonidae. This species is not as common in the aquarium trade as some other cardinalfish, but it is appreciated for its striking appearance and peaceful demeanor. They are nocturnal by nature and can often be seen hiding in crevices or among coral branches during the day.

Care

Ehrenberg's Cardinalfish are relatively easy to care for, making them suitable for both beginner and advanced aquarists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish are not aggressive and can be kept with other non-predatory tank mates. They prefer a varied diet of meaty foods such as brine shrimp, mysis shrimp, and other small invertebrates.

Reproduction

Like many cardinalfish, Cheilodipterus lachneri is a mouthbrooder. The male will carry the fertilized eggs in his mouth until they hatch, providing protection from predators. This fascinating reproductive behavior can sometimes be observed in the home aquarium if the environment is stable and the fish are well cared for.

Habitat

Ehrenberg's Cardinalfish is found in the Western Indian Ocean, including the Red Sea and the Gulf of Aden. They typically inhabit coral reefs and lagoons, often associating with branching corals where they can seek refuge. In the wild, they are usually found at depths ranging from shallow waters to about 30 meters.
