Common name: whitestar cardinalfish

General information

Ehrenberg's Cardinalfish, scientifically known as Apogon lachneri, is a small and peaceful marine fish that is suitable for many saltwater aquariums. This species is part of the Apogonidae family, which is known for its nocturnal behavior and mouthbrooding reproductive strategy. Ehrenberg's Cardinalfish has a subtle beauty, with a silvery body and a distinctive dark spot at the base of the tail fin, which can be a helpful identifier.

Care

Ehrenberg's Cardinalfish are relatively easy to care for, making them a good choice for both beginner and experienced aquarists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish prefer dim lighting, mimicking their natural dusk and dawn activity in the wild. A varied diet of small meaty foods, such as mysis shrimp and brine shrimp, will keep them healthy and vibrant.

Reproduction

Like many cardinalfish, Apogon lachneri exhibits mouthbrooding behavior. The male carries the fertilized eggs in his mouth until they hatch, providing protection from predators. This fascinating reproductive strategy can sometimes be observed in the home aquarium, offering aquarists a unique opportunity to witness parental care in fish.

Habitat

Ehrenberg's Cardinalfish is found in the Western Indian Ocean, including the Red Sea and Gulf of Aden. They typically inhabit shallow reefs and lagoons, often seeking shelter among corals and rocky crevices. In the aquarium, replicating this environment with live rock structures will provide a sense of security and natural habitat for these fish.
