This variety of Anthias does best in an aquarium with low, indirect lighting or its brilliant colors will fade. Although preferring to remain at the mid-tank level, they have been found at depths up to 600 feet in the wild. A 100 gallon tank will suffice for one fish, however, if keeping a group, a 180 gallon tank should be used since the Squareback Anthias appreciates plenty of room to swim.
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.
