Care

Hawaiian Anthias are moderately challenging to keep due to their specific dietary and environmental needs. They thrive in well-established aquariums with plenty of swimming space and stable water conditions. These fish require a diet rich in zooplankton and should be fed multiple times a day to maintain their health and coloration. It's important to note that sudden changes in water parameters can be stressful for them, so consistency is key.

Reproduction

In the wild, Pseudanthias hawaiiensis forms harems consisting of a single dominant male and several females. If the male perishes, the largest female will often undergo a sex change and take his place. In the aquarium, breeding these fish can be challenging, but with the right conditions and a well-structured social group, it is possible to observe their fascinating reproductive behaviors.

Habitat

Native to the Hawaiian Islands, the Hawaiian Anthias is typically found at depths ranging from 60 to 200 feet in the wild. They prefer areas with strong currents and clear water where they can feed on the abundant plankton. In the aquarium, replicating their natural environment with live rock for hiding and a strong water flow will help promote their well-being.
