Diet Details
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 Level
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.
