Common name: Longfin anthias

General information

The Longfin Anthias, scientifically known as Pseudanthias ventralis, is a vibrant and active fish that adds a splash of color to any reef aquarium. This species is part of the Anthiinae subfamily, which is known for its brightly colored members. The males are particularly striking with their elongated dorsal and anal fins, and a color palette that includes shades of pink, purple, and yellow.

Care

Longfin 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. A diet of small, meaty foods should be offered multiple times a day to maintain their health and coloration. It's also important to keep them in groups, as they are a shoaling species in the wild, with one dominant male and several females.

Reproduction

In the aquarium, Longfin Anthias can be difficult to breed. They are protogynous hermaphrodites, meaning females have the ability to turn into males if the dominant male is lost. Breeding success requires excellent water quality and a stress-free environment. The male will perform elaborate displays to entice females to spawn.

Habitat

Pseudanthias ventralis is found in the Western Pacific, from the Great Barrier Reef to the islands of Micronesia. They typically inhabit outer reef slopes and drop-offs, where they can be seen in large aggregations, swimming above the reef in depths ranging from 25 to 60 meters (80 to 200 feet).
