The Square Spot Anthias has a unique colour variation. The body of the female is predominantly yellow with a lavender belly, and often a thin blue line extending from nose to pectoral fin. Males are predominantly pink with a lavender belly and have a lighter rectangular shape on the side.
This species of Anthias does best in an aquarium with low, indirect lighting or its brilliant colours will fade. Although preferring to remain at the mid-tank level, they have been found at depths up to 600 feet in the wild.
Anthias species all share the trait of being hermaphroditic. If a dominant male perishes, the largest female of the group will often morph to take its place.
Once acclimated to a new aquarium, Anthias do best when fed a varied diet of frozen mysis shrimp, enriched frozen brine shrimp, and over time may eat high-quality flake foods offered in small quantities throughout the day. An attached refugium cultivating copepods and amphipods provides a steady supply of nutritious live food sure to keep this active planktivore content.
