Scientific name: Pseudanthias sheni Randall & Allen, 1989

General information

Shen's Anthias (Pseudanthias sheni) is a vibrant and colorful reef fish that is highly sought after by aquarists for its striking appearance. Males exhibit a rich pink to red coloration with a yellow stripe running from the snout through the eye to the pectoral fin base, while females are more subdued in color, typically showing a yellowish-orange hue. This species is relatively new to the aquarium trade and is often admired for its active swimming behavior and schooling nature in the wild.

Care

Caring for Shen's Anthias requires a well-established aquarium with plenty of swimming space and hiding places among live rock. They thrive in groups, so it's recommended to keep a small harem consisting of one male and several females. A varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood is essential for their health and coloration. Consistent water quality and parameters are crucial for the well-being of these fish.

Reproduction

In the aquarium, Shen's Anthias can spawn if they are kept in optimal conditions. The dominant male will display to females and, if receptive, spawning will occur. Eggs are pelagic, and raising the larvae can be challenging due to their small size and specific dietary requirements.

Habitat

Shen's Anthias is found in the Western Pacific, particularly around Taiwan and the Philippines. They inhabit outer reef slopes and drop-offs, typically at depths ranging from 20 to 60 meters. In these areas, they form large aggregations, swimming above the reef and feeding on zooplankton.
