Care

Ornate Anthias are moderately challenging to keep due to their specific dietary and social requirements. They thrive in well-established aquariums with plenty of swimming space and rockwork for hiding. These fish are planktivores in the wild, so they require a diet rich in zooplankton and high-quality marine flake or pellet food to maintain their color and health. Frequent feedings are recommended as they have a high metabolism.

Reproduction

In the home aquarium, breeding Ornate Anthias can be a rewarding challenge. They exhibit a protogynous hermaphroditism, where females have the potential to turn into males if the dominant male is no longer present. Breeding requires a stable, stress-free environment and a well-conditioned group with one male and several females.

Habitat

Ornate Anthias are found in the Western Pacific Ocean, typically around coral reefs and steep outer reef slopes. They prefer depths ranging from 25 to 60 meters, where they form large aggregations in the water column above the reef.

Geographical distribution includes areas such as the Philippines, Indonesia, and the Solomon Islands. Their preference for deeper waters can make them less common in shallow reef aquariums, but with the right conditions, they can be a stunning addition to a home aquarium.
