Care

Spotted Cardinalfish are relatively easy to care for, but they do best in a well-established aquarium with plenty of hiding places. They are a schooling species, so keeping them in groups of five or more can help promote natural behavior and reduce stress. A varied diet of small meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood will help maintain their health and coloration.

Reproduction

In the wild, Spotted Cardinalfish are mouthbrooders, with males carrying the eggs in their mouths until they hatch. This fascinating reproductive behavior can also be observed in the home aquarium if the environment is stable and the fish are well-fed. Breeding can be a rewarding experience for the dedicated hobbyist.

Habitat

Ostorhinchus maculiferus is found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, north to the Ryukyu Islands, and south to New Caledonia and Tonga. They inhabit coral reefs and lagoons, often hiding in caves or among coral branches during the day.
