Care

Orbiculate Cardinalfish are relatively hardy and can adapt to a range of aquarium conditions. They prefer a well-established tank with plenty of hiding places and a peaceful environment. They are nocturnal and may hide during the day. 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, Amblyglyphidodon orbicularis is a mouthbrooder. The male will incubate the eggs in his mouth until they hatch, providing protection from predators. This fascinating reproductive behavior can sometimes be observed in the home aquarium, offering a unique educational opportunity for aquarists.

Habitat

The Orbiculate Cardinalfish 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. They typically inhabit coral reefs and lagoons, often sheltering in staghorn coral thickets during the day.
