The Powder Blue Tang, also known as the Powder Blue Surgeonfish, is a popular and striking species of saltwater fish that is native to the Indo-Pacific region. These fish are named for their bright blue coloration, which is accented by a black mask around the eyes and a yellow dorsal fin.


These saltwater fish require a larger tank size of at least 125 gallons with plenty of swimming space, hiding places, and live rock for grazing. They are relatively hardy and can adapt to a variety of water conditions, but they prefer a stable environment with consistent water parameters and a salinity level between 1.020-1.025.


The Powder Blue Tang can grow up to 10 inches in length, making them one of the larger species of tang. They are generally peaceful but can become aggressive towards other tangs or fish with a similar body shape or coloration. They are also known to be prone to territorial behavior, especially when they reach sexual maturity.


These fish are herbivores and require a diet that is high in vegetable matter. They will happily graze on a variety of seaweed, algae, and other plant-based foods, as well as high-quality pellets or frozen foods designed for herbivorous fish.
