Common name: Orange-Lined Cardinalfish

General information

The Orange-Lined Cardinalfish, Ostorhinchus oxina, is a small and colorful marine fish that is a popular choice among aquarists due to its peaceful nature and striking appearance. It is characterized by its vibrant orange stripes that run the length of its body, interspersed with silvery-blue hues.

Care

This species is well-suited for a community aquarium with other peaceful fish. They prefer a tank with plenty of hiding places and a subdued lighting setup to mimic their natural environment. They are nocturnal feeders, so feeding should occur in the evening with a diet consisting of small meaty foods like mysis shrimp and brine shrimp.

Reproduction

Orange-Lined Cardinalfish are mouthbrooders, with the male carrying the eggs in his mouth until they hatch. This fascinating reproductive behavior can sometimes be observed in the home aquarium, offering a unique spectacle for the hobbyist.

Habitat

Native to the Western Pacific, Ostorhinchus oxina is typically found in coral-rich areas and lagoons. They tend to stay close to the bottom, often seeking refuge among the corals and rocks during the day.
