Common name: Fivelined cardinalfish

General information

The Five-lined Cardinalfish, Cheilodipterus quinquelineatus, is a striking species known for its nocturnal habits and the five distinct longitudinal lines that run across its body. These lines are typically white or light blue, contrasting with the fish's darker body coloration. This species is relatively small, making it a suitable choice for various aquarium sizes.

In the wild, these fish are often found in groups, hovering in caves or under ledges during the day. At night, they become more active, venturing out to feed. Their peaceful nature and attractive appearance make them a popular choice among aquarists.

Care

Five-lined Cardinalfish are hardy and adaptable, making them a good choice for both beginner and intermediate aquarists. They thrive in a well-established aquarium with plenty of hiding places and a peaceful community. These fish are carnivorous, and their diet should include a variety of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood.

It's important to maintain high water quality and stable parameters to keep these fish healthy. They can be shy and may require time to acclimate to the aquarium environment, but once settled, they are a delightful addition to a reef or fish-only setup.

Reproduction

In the aquarium, Five-lined Cardinalfish may spawn if they are comfortable and well-fed. They are mouthbrooders, with the male carrying the eggs in his mouth until they hatch. This fascinating reproductive behavior can be observed in a home aquarium if conditions are right.

Habitat

Cheilodipterus quinquelineatus is native to the Indo-Pacific region, where it inhabits coral reefs and lagoons. They prefer areas with plenty of cover and can often be found at depths where light penetration is moderate, allowing them to retreat into shadows during the day.
