Common name: Red-belted anthias

General information

The Orangeback Fairy Wrasse, scientifically known as Pseudanthias rubrizonatus, is a vibrant and active fish that adds a splash of color to any saltwater aquarium. This species is part of the Anthiinae subfamily, which is known for its brightly colored members. The males of this species are particularly striking with their orange dorsal area and iridescent blue body, while females tend to have a more subdued coloration.

Care

Orangeback Fairy Wrasses are relatively hardy and can adapt to life in a well-established aquarium. They require a tank with plenty of live rock for hiding and foraging. A tight-fitting lid is also essential, as these wrasses are known jumpers. They thrive in a peaceful community tank but can become territorial with other fairy wrasses. A varied diet of meaty foods, such as mysis shrimp and brine shrimp, will help maintain their vibrant colors and health.

Reproduction

In the wild, Orangeback Fairy Wrasses form harems consisting of one dominant male and several females. They are protogynous hermaphrodites, meaning females have the ability to turn into males if the dominant male is lost. Breeding in captivity is challenging but possible with a well-maintained reef system and stable group dynamics.

Habitat

Pseudanthias rubrizonatus is found in the Western Pacific, particularly around the Coral Sea, Great Barrier Reef, and Solomon Islands. They inhabit coral-rich areas and slopes, typically at depths ranging from 25 to 60 meters. In the aquarium, replicating their natural environment with a variety of corals and ample swimming space is beneficial for their well-being.
