Care
Ostorhinchus parvulus is suitable for small to medium-sized aquariums. They prefer a dimly lit tank with plenty of hiding places among live rock or soft corals. These cardinalfish are hardy and can adapt to a variety of aquarium conditions, but they do best in a stable environment with a consistent day-night cycle to mimic their natural habitat.
Reproduction
Like many cardinalfish, Ostorhinchus parvulus is a mouthbrooder. The male will carry the fertilized eggs in his mouth until they hatch, providing protection from predators. This fascinating reproductive behavior can sometimes be observed in the home aquarium if the fish are well cared for and feel secure.
Habitat
The Small-Scaled Cardinalfish is found in the Western Pacific, from the Philippines to northern Australia. They inhabit coral reefs and lagoons, often hiding in crevices or among the branches of soft corals during the day. At night, they emerge to feed on small invertebrates and plankton.
