Care

Ostorhinchus griffini is an adaptable species that can thrive in a well-established aquarium with stable water conditions. They prefer a tank with plenty of hiding spots among live rock or dense vegetation. Being a schooling fish, it is recommended to keep them in groups of at least five individuals to promote natural behavior and reduce stress. They are not aggressive and can be kept with other peaceful tank mates.

Their diet should consist of a variety of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood. Regular feeding and a balanced diet will help maintain their health and coloration.

Reproduction

Like many cardinalfish, Ostorhinchus griffini is a mouthbrooder. The males incubate the eggs in their mouths until they hatch, providing protection from potential predators. This fascinating reproductive behavior can sometimes be observed in the home aquarium, offering a unique opportunity for aquarists to witness.

Habitat

Griffin's Cardinalfish is found in the Western Pacific, from the Philippines to northern Australia. They typically inhabit coral reefs and lagoons, often seeking refuge in caves and crevices during the day. In the wild, they can be found at depths ranging from shallow waters to about 30 meters.
