Care

Ruby Cardinalfish are suitable for both novice and experienced aquarists. They thrive in well-established aquariums with stable water conditions and plenty of hiding spaces.

A varied diet of small meaty foods, such as brine shrimp and mysis, will keep them healthy and maintain their coloration.

Habitat

Ostorhinchus selas is found in the Western Pacific, from the Philippines to northern Australia. They typically inhabit coral reefs and lagoons, often seeking refuge among the branches of corals or in crevices during the day.
