Tricolor/Red Belted Anthias – Male
Pseudanthias rubrizonatus

The Tricolor Anthias is a stunning deepwater reef species prized for its vibrant gradients of color and elegant schooling behavior. Males display brilliant rose to magenta bodies, a glowing orange dorsal stripe, and electric yellow highlights in the fins—an eye-catching combination that adds movement and color to open-water reef zones. Native to the Indo-Pacific, Pseudanthias rubrizonatus is best kept in groups, with one male and multiple females, in large, well-oxygenated reef systems. Their peaceful nature and vibrant display make them a high-impact addition for advanced reef aquarists.
