Common name: Luminous cardinalfish

General information

The Graceful Dartfish, Rhabdamia gracilis, is a small and slender fish known for its peaceful demeanor and striking appearance. It is characterized by its elongated body, transparent fins, and a prominent lateral line. The body is usually pale with a hint of yellow, and the eyes are often accented with a touch of red. This species is not as common in the aquarium trade as some other dartfish, but it can be a delightful addition to a peaceful community tank.

Care

Graceful Dartfish are best kept in an aquarium with a sandy substrate and plenty of hiding places, such as caves or overhangs. They are jumpers, so a tightly fitting lid is essential to prevent escape. These fish are generally peaceful and can be kept with other non-aggressive tank mates. They thrive in stable water conditions and should be fed a varied diet of meaty foods, such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the wild, Rhabdamia gracilis forms pairs or small groups and spawns pelagic eggs that are dispersed by the current. In the aquarium, breeding is rare, but if conditions are right, they may spawn. The larvae are planktonic and would require specialized care to raise in captivity.

Habitat

Rhabdamia gracilis is found in the Indo-Pacific region, from the Red Sea and East Africa to the Western Pacific. They inhabit coral reefs and lagoons, often swimming in open water above the reef or hiding among the branches of corals. They are typically found at depths ranging from 2 to 30 meters.
