Common name: Truncate cardinalfish

General information

The Singapore Cardinalfish, Cheilodipterus singapurensis, is a lesser-known species in the aquarium trade but is gaining popularity due to its striking appearance and peaceful demeanor. This species is characterized by its silver body with a distinctive black vertical stripe running through the eye and another at the base of the tail fin. They are nocturnal by nature and can grow up to 12 cm in length.

Care

Singapore Cardinalfish are relatively hardy and suitable for both novice and experienced aquarists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish are carnivorous and prefer a diet of small meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood. Consistent feeding routines and varied diet will help maintain their health and coloration.

Reproduction

In the wild, Singapore 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, making them an interesting species for aquarists interested in breeding.

Habitat

Cheilodipterus singapurensis is found in the Western Pacific, from the Andaman Sea to the Philippines and Indonesia. They typically inhabit coral reefs and lagoons, often taking refuge in caves and crevices during the day. In the aquarium, replicating their natural environment with live rock structures and dim lighting can help these fish feel more at home.
