Care
Narrowstripe Cardinalfish are relatively easy to care for, making them suitable for both novice and experienced aquarists. They prefer an aquarium with plenty of hiding places and a peaceful environment. These fish are not aggressive and can be kept with other non-aggressive tank mates. They thrive on a varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood.
Reproduction
Like many cardinalfish, Ostorhinchus angustatus 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.
Habitat
The Narrowstripe Cardinalfish is found in the Western Pacific, from the Philippines to Australia. They typically inhabit coral reefs and lagoons, often seeking shelter among corals and rocks. In the wild, they are usually found at depths ranging from shallow waters to about 30 meters.
