The Rubrolineatus Anthias, Pseudanthias rubrolineatus, 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 distinct red-orange coloration with a soft purple hue covering its eyelids with a bold red line crossing half of its body and filaments on both of its fins. As the Rubrolineatus Anthias matures, the vibrancy of its characteristic stripe fades. 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 hardy and can be kept in a reef tank setting with plenty of live rock. 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.
