Sunset Anthias (Pseudanthias parvirostris) – Complete Care Guide

General Information

The Sunset Anthias (Pseudanthias parvirostris) is a stunning and vibrant addition to any reef aquarium. Known for its striking coloration, this species features a gradient of pink, orange, and yellow hues, reminiscent of a tropical sunset. Its common name, "Sunset Anthias," perfectly captures its radiant appearance. This species is native to the Indo-Pacific region, where it inhabits coral reefs and lagoons, often found in schools hovering above reef slopes.

This species is a favorite among aquarists due to its beauty and relatively peaceful nature. However, it requires a bit more care and attention compared to beginner-friendly fish, making it better suited for intermediate to advanced hobbyists. Sunset Anthias are often confused with other anthias species, but their smaller size and unique coloration help distinguish them from similar species like Pseudanthias squamipinnis.

Care

Sunset Anthias thrive in well-established reef aquariums with plenty of live rock and open swimming space. They prefer tanks with moderate to strong water flow and stable water parameters. A tank volume of at least 300 liters is recommended to accommodate their active swimming behavior and social nature.

This species is best kept in groups, with one male and several females, to mimic their natural harem structure. Ensure the tank has plenty of hiding spots and overhangs to provide security and reduce stress. Sunset Anthias are sensitive to poor water quality, so regular maintenance and water changes are essential.

Diet and Feeding

In the wild, Sunset Anthias are planktivores, feeding on zooplankton and other small suspended particles. In captivity, they require a varied diet to maintain their vibrant coloration and health. Offer high-quality frozen foods such as mysis shrimp, brine shrimp, and copepods, along with enriched flake or pellet foods designed for marine fish.

Feed them small portions multiple times a day, as they have high metabolisms and are accustomed to frequent feeding in the wild. Providing a diverse diet will not only keep them healthy but also enhance their natural colors.

Behavior and Compatibility

Sunset Anthias are peaceful fish that do well in community reef tanks. They are best kept in groups, as they form harems in the wild, with one dominant male and several females. This social structure helps reduce aggression and promotes natural behavior.

While generally peaceful, males may display territorial behavior towards other males or similarly shaped fish. It is advisable to keep only one male per tank unless the aquarium is very large. Sunset Anthias are compatible with a wide range of reef-safe fish, invertebrates, and corals, making them an excellent choice for mixed-species tanks.

Reproduction

Like many anthias species, Sunset Anthias are protogynous hermaphrodites, meaning all individuals are born female, and the dominant individual in a group will transition to male. This fascinating reproductive strategy ensures the stability of their social structure. Breeding in captivity is rare but possible with careful attention to water quality, diet, and tank setup. Spawning typically occurs at dusk, with the male performing a courtship display to attract females.

Habitat

Sunset Anthias are native to the Indo-Pacific region, including areas such as the Maldives, Indonesia, and the Philippines. They inhabit coral reefs and lagoons, often found at depths ranging from 10 to 40 meters. In the wild, they form large schools that hover above reef slopes, feeding on plankton carried by the currents.

To replicate their natural habitat, provide a tank with plenty of live rock, overhangs, and caves, along with open swimming areas. Moderate to strong water flow is ideal, as it mimics the currents of their native reef environments.
