Care
Moluccan Cardinalfish thrive in a well-established aquarium with plenty of hiding places and a peaceful environment. They prefer dim lighting, mimicking their natural dusk and dawn activity in the wild. A varied diet of small meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood will help maintain their health and coloration.
Reproduction
Like many cardinalfish, Ostorhinchus moluccensis are mouthbrooders. The males carry the fertilized eggs in their mouth until they hatch, providing a fascinating display for aquarists. This reproductive strategy also provides a high survival rate for the offspring, which can be an interesting aspect of their care in captivity.
Habitat
Moluccan Cardinalfish are found in the Western Pacific, from Indonesia to Papua New Guinea, and north to the Philippines. They typically inhabit coral reefs and lagoons, often sheltering in caves or among coral branches during the day. They can be found at depths ranging from shallow waters to about 20 meters.
