Common name: Redfin cardinalfish

General information

The Red Sea Cardinalfish, scientifically known as Pristicon rhodopterus, is a captivating species popular among aquarists for its striking appearance and peaceful demeanor. This species is characterized by its vibrant red coloration, which can vary in intensity depending on the individual and the environment. They are small, typically reaching about 8 cm in length, making them suitable for a variety of tank sizes.

Cardinalfish are nocturnal by nature and tend to be shy during the day, often seeking refuge in rockwork or among corals. They are a schooling species in the wild and exhibit this behavior in the aquarium as well, so it's recommended to keep them in groups for their well-being.

Care

Red Sea Cardinalfish are relatively easy to care for, but they do best in a well-established aquarium with stable water conditions. They prefer a tank with plenty of hiding places and subdued lighting to mimic their natural habitat. A varied diet of small meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood will help maintain their health and coloration.

Reproduction

Like many cardinalfish, Pristicon rhodopterus are mouthbrooders. The males carry the fertilized eggs in their mouths until they hatch, providing protection from predators. This fascinating reproductive behavior can sometimes be observed in the home aquarium, offering a unique spectacle for the hobbyist.

Habitat

Pristicon rhodopterus is native to the Red Sea and the Gulf of Aden. They are typically found in shallow, coastal waters and around coral reefs where they can take advantage of the complex structures for shelter and foraging.
