Common name: Vanikoro sweeper

General information

The Vanicolor Sweeper, Pempheris vanicolensis, is a small, nocturnal reef fish known for its schooling behavior and striking golden coloration. It is a member of the family Pempheridae, commonly referred to as sweepers. These fish are appreciated for their peaceful nature and the dynamic visual interest they add to a reef aquarium, especially when kept in groups.

Care

Vanicolor Sweepers are relatively hardy and can adapt to life in captivity if provided with the right conditions. They thrive in well-established aquariums with plenty of hiding spaces and subdued lighting to mimic their natural nocturnal habitat. They are not aggressive and can be kept with a variety of other peaceful fish. A varied diet of small meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood is essential for their health.

Reproduction

In the wild, Vanicolor Sweepers form large aggregations during spawning, releasing eggs and sperm into the water column where fertilization occurs. In the home aquarium, breeding is rare, but with a large enough group and optimal conditions, it is possible to observe spawning behavior.

Habitat

Vanicolor Sweepers are found in the Indo-Pacific region, from the Red Sea to South Africa and east to Samoa, north to southern Japan, and south to Australia. They prefer reef slopes and lagoons, often seeking refuge in caves and under ledges during the day. At night, they emerge to feed in the open water above the reef.
