Common name: Bridled cardinalfish

General information

The Bridled Cardinalfish, scientifically known as Pristiapogon fraenatus, is a small and peaceful marine fish that is well-suited for the home aquarium. They are part of the family Apogonidae, which is known for its hardy and nocturnal species. These fish are characterized by their silver body with a distinctive black line running from the snout through the eye and along the body, ending in a spot on the caudal peduncle.

Care

Bridled Cardinalfish are relatively easy to care for, making them a good choice for beginner and intermediate aquarists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish prefer dim lighting, as they are nocturnal by nature. A varied diet of small meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood will help maintain their health and coloration.

Reproduction

In the wild, Bridled 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 if the environment is stress-free and well-maintained. The male will not eat during this brooding period, which can last for several weeks.

Habitat

Pristiapogon fraenatus is found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, north to the Ryukyu Islands, and south to New Caledonia. They typically inhabit coral reefs and lagoons, often hiding in crevices or among coral branches during the day. At night, they emerge to feed on zooplankton and small invertebrates.
