Bimaculatus Anthias Male

Bring vivid tropical color and graceful mid-water movement to your reef aquarium with the Bicolor Anthias (Pseudanthias bicolor). This stunning Indo-Pacific species showcases a dramatic two-tone gradient—bright sunshine yellow along the front half of the body that transitions into deep magenta and violet toward the tail. Peaceful, reef-safe, and highly active, the Bicolor Anthias adds constant motion and eye-catching color to reef and community marine aquariums.

Naturally a schooling fish, the Bicolor Anthias thrives in stable, well-oxygenated systems with plenty of open swimming space and rockwork for shelter. It performs best in small groups and appreciates a varied carnivorous diet consisting of mysis shrimp, brine shrimp, marine plankton, and other high-quality frozen foods. Ideal for hobbyists seeking a hardy, vibrant mid-water swimmer, this species brings long-lasting beauty and natural reef behavior to any saltwater setup.
