Care

Ostorhinchus wassinki is a hardy species that adapts well to life in captivity. They prefer a well-structured environment with plenty of hiding places, such as caves or overhangs. A peaceful community tank with other non-aggressive fish is ideal. They thrive on a varied diet that includes small meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the wild, Wassink's Cardinalfish are mouthbrooders, with males taking on the responsibility of carrying the eggs in their mouths until they hatch. This fascinating reproductive behavior can also be observed in the home aquarium, making them an interesting species for hobbyists interested in breeding marine fish.

Habitat

Native to the Western Pacific, Ostorhinchus wassinki is typically found in coral-rich areas and lagoons. They are often associated with reef environments where they can find shelter among the corals and rockwork.
