Description
The Black-spot Cardinalfish is a small, peaceful marine fish known for its translucent body adorned with iridescent stripes and a distinctive black spot at the base of its caudal fin. These nocturnal predators typically hide in reef structures during the day, emerging at night to feed on zooplankton. They are best kept in small groups in a reef aquarium.
