Common name: Brassy cardinalfish

General information

The Yellow-striped Cardinalfish, Ostorhinchus flavus, is a small and peaceful marine fish that is well-suited for community and reef aquariums. Its striking yellow stripes and peaceful demeanor make it a favorite among aquarists. This species is nocturnal and tends to be more active during the evening or with subdued lighting.

Care

Ostorhinchus flavus is relatively easy to care for. It prefers a well-established aquarium with plenty of hiding places and a peaceful environment. These fish are schooling by nature and do best when kept in groups of five or more. They are not aggressive eaters, so care should be taken to ensure they receive enough food when housed with more boisterous species.

Reproduction

In the wild, Yellow-striped Cardinalfish are mouthbrooders, with males incubating the eggs in their mouths until they hatch. This behavior can also be observed in the home aquarium, making them an interesting species for aquarists interested in observing reproductive behaviors.

Habitat

Native to the Western Pacific, Ostorhinchus flavus can be found in coral reefs and lagoons, often seeking refuge among corals and rocks. They typically inhabit depths from 1 to 18 meters.

Geographical distribution includes areas from the Andaman Sea to Fiji, and from southern Japan to the Great Barrier Reef.
