Scientific name: Pseudanthias bicolor (Randall, 1979)

General information

The Bicolor Anthias, scientifically known as Pseudanthias bicolor, is a vibrant and active fish that adds a splash of color to any reef aquarium. This species is part of the Serranidae family and is known for its striking two-tone coloration, with the anterior part of the body being a vivid magenta and the posterior part a bright yellow-orange. They are commonly found in the Indo-Pacific region and are a popular choice among aquarists due to their beauty and relatively peaceful nature.

Care

Bicolor Anthias are best kept in a well-established aquarium with plenty of live rock for hiding and grazing. They thrive in a group, preferably with one male to several females, as they are a haremic species. The tank should have a tight-fitting lid as they can be prone to jumping when startled. A varied diet of meaty foods, such as mysis shrimp and finely chopped seafood, supplemented with high-quality pellets or flakes, will help maintain their coloration and health.

Reproduction

In the wild, Bicolor Anthias form harems consisting of a single dominant male and numerous females. They are protogynous hermaphrodites, meaning females have the ability to turn into males if the dominant male perishes. In the aquarium, breeding can be challenging, but with stable conditions and a well-structured social group, it is possible to observe spawning behavior.

Habitat

Pseudanthias bicolor is typically found in coral-rich areas and slopes of outer reefs, usually at depths ranging from 10 to 70 meters. They prefer strong water movement and clear waters where they can feed on zooplankton that drifts by in the current.
