Bicolor Anthias Fish

The Bicolor Pseudanthias, also known as the Bicolor Anthias, is a captivating and active fish that adds a splash of color to any reef aquarium. Its body is a striking combination of vibrant yellow on the anterior half, transitioning to a beautiful purple or pink on the posterior half, with a distinctive purple stripe running from the eye to the pectoral fin.

A minimum tank size of 70 gallons is recommended to provide ample swimming space and accommodate a small group. These fish thrive in a well-established reef environment with plenty of live rock offering hiding places and perching spots. While generally considered reef-safe, they may occasionally nip at certain sessile invertebrates, so careful observation is advised.

In the aquarium, the Bicolor Pseudanthias typically reaches a size of around 4-5 inches. They are protogynous hermaphrodites, meaning they are born female and can change to male. Distinguishing between males and females based on color alone is difficult.

Their diet should consist of a variety of meaty foods, including mysis shrimp, enriched brine shrimp, and other high-quality frozen preparations. Offering small, frequent feedings throughout the day is beneficial for their health and well-being.
