Common name: St. Joseph's Cardinalfish

General information

The St. Joseph's Cardinalfish, Eurato sanctijosephi, is a small and colorful marine fish that is relatively new to the aquarium trade. This species is known for its peaceful demeanor and striking appearance, with a deep red to burgundy body and a contrasting bright yellow tail. They are nocturnal by nature and tend to be shy, often seeking refuge among rocks and corals during the day.

Care

St. Joseph's Cardinalfish are suitable for both beginner and advanced aquarists due to their hardy nature. They thrive in well-established aquariums with plenty of hiding places and a peaceful community. These fish prefer dim lighting and a gentle water flow. A varied diet of small meaty foods, such as mysis shrimp and brine shrimp, will help maintain their color and health.

Reproduction

Like many cardinalfish, Eurato sanctijosephi exhibits mouthbrooding behavior. The male carries the fertilized eggs in his mouth until they hatch, providing protection from predators. This fascinating reproductive strategy can sometimes be observed in the home aquarium, offering a unique spectacle for the aquarist.

Habitat

Eurato sanctijosephi is found in the Western Pacific, particularly around the Philippines. They inhabit coral reefs and are often associated with sheltered lagoons and reef slopes. In the wild, they can be found at various depths, typically from shallow waters to deeper reef areas.
