Common name: Goldenback Basslet

General information

The Goldenback Basslet, scientifically known as Pseudanthias aurulentus, is a strikingly beautiful fish that adds a splash of color to any reef aquarium. This species is part of the Anthias group, which are known for their bright colors and active swimming behavior. The males of this species are particularly vibrant, with a golden yellow back that transitions to a pinkish-purple towards the belly, accented with bright red fins.

Care

Goldenback Basslets are moderately easy to care for but do have some specific requirements. They thrive in well-established aquariums with plenty of live rock for hiding and a stable environment. These fish are planktivores in the wild, so they require a diet rich in zooplankton or high-quality, small-sized marine foods offered multiple times a day to maintain their health and coloration.

Reproduction

Like many Anthias, Pseudanthias aurulentus are hermaphroditic, with the dominant male controlling a harem of females. In the aquarium, breeding can occur if the environment is stable and the group is well-fed. The male will display an elaborate courtship dance to entice the females to spawn.

Habitat

Goldenback Basslets are found in the Western Pacific, particularly around the Coral Sea and Great Barrier Reef. They prefer steep reef slopes and drop-offs, where they can be seen swimming in loose aggregations, feeding on plankton in the water column.
