The Purple Queen Anthias, Pseudanthias tuka, is hermaphroditic meaning all are born females, and when needed the dominant female turns into male. Though they are one of the few Anthias species that does not display sexual dimorphism. They feature a muted pink/purple body, blue edging on its fins, and a multi-colored face with a yellow chin. They can be kept as a mated pair, or in a small school of females. Avoid keeping two males in the same tank, as it can lead to extreme aggression.

They are peaceful and can be kept in a reef tank setting with plenty of live rock, but since they are one of the more sensitive genus of Anthias, they will require expert care. 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.
