Common name: Stocky anthias

General information

The Stocky Anthias, also known as the Humpback Anthias or Highfin Anthias, is a vibrant and active fish that adds a splash of color to any reef aquarium. Pseudanthias hypselosoma is part of the Anthiinae subfamily, which is known for its brightly colored members. This species is particularly noted for its sexual dimorphism, with males displaying a more intense coloration and a distinctive hump on the dorsal fin.

Care

Stocky 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 numerous hiding places. These fish are planktivores in the wild, so they require a diet of small, meaty foods offered multiple times a day to maintain their health and coloration in captivity.

Reproduction

Like many anthias, Pseudanthias hypselosoma forms harems consisting of one dominant male and several females. If the male dies, the largest female will often undergo a sex change to become the new male, a process known as protogynous hermaphroditism. Breeding in captivity is rare but possible with optimal water conditions and a stress-free environment.

Habitat

Stocky Anthias are found in the Western Pacific, from the Philippines to northern Australia. They prefer steep outer reef slopes and are typically found at depths ranging from 25 to 60 meters. In the aquarium, replicating their natural habitat with strong water movement and ample rockwork can help these fish feel at home.
