Appearance

A small, stocky cardinalfish with a dark reddish-brown to olive body and two distinctive white or pale bands (stripes) crossing the head and gill area, giving it its "bridled" appearance. The body is robust and slightly compressed, with a large mouth typical of apogonids, and the overall coloration may vary from brownish-red to orange-red depending on lighting and mood.

Diet and feeding

Primarily a nocturnal planktivore and micro-predator in the wild. In captivity, feed high-quality frozen foods such as mysis shrimp, copepods, and small frozen zooplankton. Multiple small feedings per day are recommended, as these fish have small mouths and prefer to feed on small particles.

Difficulty and care for the Bridled Cardinalfish

Bridled Cardinalfish are moderately hardy and suitable for established reef tanks with stable conditions. They require dim lighting and plenty of hiding places, and can be sensitive to water quality fluctuations and aggressive tankmates.

Marine ich, Fin rot, Swim bladder disorder, Bacterial infections, Fungal infections

Origin and habitat

Indo-Pacific from the Red Sea and East Africa to the Hawaiian Islands and French Polynesia, typically found in sheltered reefs and lagoons at depths of 5–50 meters.
