Common name: Cardinalfish

Cheilodipterus, commonly known as Cardinalfish, is a genus of small, nocturnal fish found in tropical and subtropical oceans worldwide. They are popular in the reefkeeping hobby due to their peaceful nature and striking appearance, often featuring bold stripes or vibrant colors. These fish typically inhabit coral reefs and lagoons, where they seek shelter during the day and hunt for small prey at night. In the aquarium, they require hiding places and a varied diet of meaty foods. Cardinalfish are also known for their unique breeding behavior, where males brood eggs in their mouths until they hatch.
