Common name: Tubelip wrasse

General information

The One-lined Rainbowfish, scientifically known as Labrichthys unilineatus, is a small and colorful wrasse species that is a delightful addition to many saltwater aquariums. This species is known for its elongated body and the distinctive single horizontal stripe running the length of its body, from which it derives its common name.

Care

One-lined Rainbowfish are relatively hardy and adaptable to aquarium life. They thrive in well-established tanks with plenty of live rock for hiding and foraging. These wrasses are active swimmers and benefit from ample swimming space. They are not overly aggressive but may show territorial behavior towards other wrasses. A varied diet of meaty foods, such as mysis shrimp and finely chopped seafood, will help maintain their health and coloration.

Reproduction

In the wild, Labrichthys unilineatus is known to be a protogynous hermaphrodite, meaning individuals start life as females and can change to males as they mature. In the aquarium, breeding is not commonly observed, but providing a stress-free environment with plenty of hiding places can encourage natural behaviors.

Habitat

The One-lined Rainbowfish is found in the Indo-Pacific region, typically inhabiting coral reefs and lagoons. They prefer areas with abundant coral growth and clear waters where they can easily hunt for small invertebrates.
