Common name: Many-lined cardinalfish

General information

The Multiline Cardinalfish, Ostorhinchus multilineatus, is a small and peaceful marine fish that is well-suited for the home aquarium. It is known for its striking appearance, with multiple horizontal lines running along its body, and its ability to adapt to a variety of tank conditions. This species is nocturnal and tends to be more active during the evening hours.

Care

Multiline Cardinalfish are relatively easy to care for, making them a good choice for beginners. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish prefer dim lighting due to their nocturnal nature. They are not picky eaters and will accept a variety of foods, including small pellets, flake foods, and frozen or live brine shrimp and mysis shrimp.

Reproduction

In the wild, Multiline Cardinalfish are mouthbrooders, with the male carrying the eggs in his mouth until they hatch. This fascinating reproductive behavior can also be observed in the home aquarium. The male will not eat during this brooding period, which can last for several weeks.

Habitat

Ostorhinchus multilineatus is found in the Western Pacific, from Indonesia to the Great Barrier Reef and west to the Solomon Islands. They inhabit coral reefs and lagoons, often sheltering in caves or among coral branches during the day. In the aquarium, they appreciate a similar environment with plenty of live rock for refuge.
