General information

The Glowlight Cardinalfish, scientifically known as Parapriacanthus ransonneti, is a small and colorful marine fish that is popular among aquarists for its striking appearance and peaceful demeanor. This species is known for its translucent body with a distinctive iridescent stripe that runs laterally from the eye to the base of the tail, giving it a glowing effect.

Care

Glowlight Cardinalfish are relatively easy to care for, making them suitable for both beginner and experienced hobbyists. They thrive in a well-established aquarium with stable water conditions and plenty of hiding places. These fish are nocturnal and prefer dimly lit environments. They are not aggressive and can be kept with other peaceful tank mates. A varied diet of small meaty foods like brine shrimp, mysis shrimp, and finely chopped seafood will help maintain their health and coloration.

Reproduction

In the wild, Glowlight Cardinalfish are mouthbrooders, with males taking on the responsibility of carrying the eggs in their mouths until they hatch. This fascinating reproductive behavior can also be observed in the home aquarium, where providing a stress-free environment can encourage breeding.

Habitat

Parapriacanthus ransonneti is found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, and north to the Ryukyu Islands. They typically inhabit coral reefs and lagoons, often found in schools hovering near reef overhangs or caves at depths ranging from shallow waters to about 30 meters.
