Common name: Bartlett's anthias

General information

Bartlett's Anthias, scientifically known as Pseudanthias bartlettorum, is a vibrant and active fish that adds a splash of color to any reef aquarium. These small, peaceful fish are part of the Serranidae family and are popular among aquarists for their striking purple and yellow hues. Males typically exhibit more intense coloration and a slightly larger size compared to females.

Care

Bartlett's Anthias are best kept in groups, with a single male to several females, in a well-established aquarium with plenty of swimming space and hiding spots. They thrive in a stable environment with consistent water quality. A varied diet of meaty foods, such as mysis shrimp and finely chopped seafood, is essential for maintaining their health and coloration.

Reproduction

In the wild, these anthias are protogynous hermaphrodites, meaning females have the ability to turn into males if the dominant male is no longer present. In the aquarium, breeding can occur if conditions are optimal, with the male performing an elaborate dance to entice females to spawn.

Habitat

Bartlett's Anthias are found in the Western Pacific, from the Philippines to Fiji, and north to the Ryukyu Islands. They prefer the upper regions of coral reefs, typically between 10 to 70 meters deep, where they can be seen swimming in large aggregations above the reef.

Aquarists should aim to replicate their natural habitat as closely as possible, with a focus on providing ample rockwork and open water for swimming.
