The pink square anthias is also known as the Squareback anthias, Squarespot anthias, Purple Blotch Basslet or Mirror anthias. The body of the female Square Yellow Anthias 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.
Anthias fish all share the trait of being hermaphroditic. If a dominant male perishes, it is not unheard of that one female will change and become a male.
Note: Anthias are somewhat difficult to keep healthy in captivity and so they should not be kept by inexperienced saltwater aquarists. Diet should include a variety of a steady supply of copepods, frozen mysis and vitamin enriched brine shrimp, as well as high quality flake foods 3-5 times daily.
