Common name: Hawaiian anthias

General information

Thompson's Anthias, scientifically known as Pseudanthias thompsoni, is a vibrant and active fish that adds a splash of color to any reef aquarium. They are part of the Anthiinae subfamily, which is known for its brightly colored members. This species is particularly admired for its striking orange and pink hues, with males typically displaying more intense coloration and a distinctive lyre-shaped tail.

Care

Thompson's Anthias are moderately challenging to keep due to their specific dietary and social needs. They thrive in well-established aquariums with plenty of swimming space and rockwork for hiding. A peaceful community tank is ideal, as they can be shy and may be outcompeted for food by more aggressive fish. They require a diet of small, meaty foods multiple times a day to maintain their health and coloration.

Reproduction

Like many anthias, Thompson's Anthias are protogynous hermaphrodites, meaning they are born female and can change to male if the dominant male is removed from the group. They form harems consisting of one male and several females. In an aquarium setting, breeding can be challenging, but providing a stress-free environment with consistent water quality may encourage spawning behavior.

Habitat

Native to the Pacific Ocean, Thompson's Anthias are typically found in deep reef slopes and drop-offs. They prefer areas with moderate to strong water currents, which help deliver their planktonic food. In the wild, they can be found at depths that are often deeper than the average home aquarium, which makes them less commonly seen in the trade compared to other anthias species.
