Common name: Blackstripe cardinalfish

General information

The Black-banded Cardinalfish, Ostorhinchus nigrofasciatus, is a striking species known for its distinctive black bands and peaceful demeanor. This small, nocturnal fish is a member of the family Apogonidae and is often sought after by aquarists for its unique appearance and compatibility with other reef inhabitants.

Care

Black-banded Cardinalfish are relatively easy to care for, making them suitable for both novice and experienced aquarists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish prefer dim lighting and a quiet environment, as they are most active at night. A varied diet of small meaty foods, such as mysis shrimp and brine shrimp, will help maintain their health and coloration.

Reproduction

In the wild, Black-banded Cardinalfish are mouthbrooders, with males incubating the eggs in their mouths until they hatch. This fascinating reproductive behavior can also be observed in the home aquarium, where successful breeding can occur if the environment is stable and stress-free.

Habitat

Ostorhinchus nigrofasciatus is found in the Western Pacific, from Indonesia to the Solomon Islands, and north to the Ryukyu Islands. They typically inhabit coral reefs and lagoons, often sheltering in caves or among coral branches during the day.
