Watanabe’s Angelfish are a show-stopping addition to any deep-water reef aquarium. They are hardy, long-lived, and require a minimum tank size of 125 gallons or larger. Acclimation to the tank should be slow and done in a tank with dim lighting and multiple hiding places. Live rock should be added to the tank to provide grazing opportunities. To ensure the well-being of the Angelfish, be sure to only house a single male with one female in the tank. Keeping two males in the same tank will result in fighting and should be avoided.
Watanabe’s Angelfish are an excellent addition to any saltwater aquarium due to their vibrant colors and unique behavior. Although they are difficult to breed, a varied diet and proper care will ensure the fish remain healthy and happy. Additionally, it is important to monitor the fish for swim bladder damage, as this species is particularly susceptible to this condition. With the right environment and diet, Watanabe’s Angelfish can thrive and make an attractive, active addition to a saltwater aquarium.
