Common name: Gon's cardinalfish

General information

Bleeker's Cardinalfish, scientifically known as Archamia bleekeri, is a small and peaceful marine fish that is well-suited for the home aquarium. This species is part of the Apogonidae family, which is known for the unique reproductive behavior of mouthbrooding. They are nocturnal by nature and have a striking appearance with their silver body and red to orange stripes running longitudinally along their sides.

Care

Bleeker's Cardinalfish are relatively easy to care for, making them a good choice for both beginner and advanced 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 active periods. A varied diet of small meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood will help maintain their health and coloration.

Reproduction

One of the most fascinating aspects of Bleeker's Cardinalfish is their mouthbrooding behavior. Males are responsible for carrying the eggs in their mouth until they hatch, providing protection from predators and ensuring a higher survival rate for the offspring. This reproductive strategy can be observed in the home aquarium, offering aquarists a unique opportunity to witness this natural phenomenon.

Habitat

Bleeker's Cardinalfish are found in the Western Pacific, from the Ryukyu Islands to Australia, and across to the Solomon Islands. They inhabit coral reefs and lagoons, often seeking shelter among corals and rocks. In the aquarium, replicating this environment with live rock structures will provide them with the necessary refuge and contribute to their well-being.
