General information

The Two-spot Bimaculatus, scientifically known as Pseudanthias bimaculatus, is a vibrant and colorful addition to any reef aquarium. This species is part of the Anthiinae subfamily, which is known for its brightly colored members that are often a highlight in the marine aquarium hobby. The males are particularly striking with their pinkish-orange bodies and two prominent spots on the dorsal fin, which give this species its common name.

Care

Bimaculatus Anthias are moderately challenging to keep due to their specific dietary and social requirements. They thrive in well-established aquariums with plenty of live rock for hiding and a strong current to mimic their natural environment. These fish are planktivores in the wild, so a diet of small, meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood, offered multiple times a day, is essential for their well-being.

Reproduction

Like many anthias species, the Two-spot Bimaculatus is a protogynous hermaphrodite, meaning females have the ability to turn into males if a dominant male is not present. They form harems consisting of one dominant male and several females. In the aquarium, breeding can occur, with the male displaying an elaborate courtship dance to entice females to spawn.

Habitat

The natural habitat of the Bimaculatus Anthias includes coral reefs and slopes in the Indo-Pacific region. They are typically found at depths ranging from 10 to 70 meters, where they swim in large aggregations above the reef, feeding on zooplankton that drifts by in the current.
