Common name: Indian Ocean pinstriped wrasse

Scientific name: Halichoeres vrolikii (Bleeker, 1855)

General information

The Pink-belly Wrasse, scientifically known as Halichoeres vrolikii, is a vibrant and active fish that adds both color and dynamism to a saltwater aquarium. It is part of the family Labridae, which is known for its diverse and often brightly colored members. This species is particularly appreciated for its striking pink abdomen, which contrasts beautifully with its yellow-green upper body.

Juveniles and females typically exhibit a silver to white coloration with a distinct pink to red belly, while males develop more intense coloration and may display a greenish back, a yellow stripe along the side, and a dark blotch on the dorsal fin.

Care

Pink-belly Wrasses are hardy and adaptable, making them suitable for both beginner and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and grazing. A sandy substrate is also important as these wrasses may bury themselves in the sand when they feel threatened or during the night.

Their diet should include a variety of meaty foods such as mysis shrimp, brine shrimp, and other prepared marine foods. It's important to feed them small amounts several times a day to maintain their health and vibrant coloration.

Reproduction

Like many wrasses, Halichoeres vrolikii is 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 in the wild, males perform elaborate courtship displays to attract females.

Habitat

The Pink-belly Wrasse is found in the Indo-Pacific region, from the eastern Indian Ocean to the western Pacific. They are typically associated with coral reefs and can be found at depths ranging from shallow lagoons to slopes down to about 30 meters.

Their natural habitat includes areas with abundant coral growth and sandy bottoms, where they can forage for small invertebrates and seek refuge from predators.
