The Powder Blue Tang is one of the most beautiful but demanding fish in the hobby, reaching a Max Size of 23 cm. It features an incredible sky-blue body, a black head, and a brilliant yellow dorsal fin. These fish are extremely territorial and sensitive to water conditions, making them a "with caution" choice for experienced keepers. They require massive water flow and a high-oxygen environment. In the aquarium, they are voracious algae eaters but will often bully any other fish that shares a similar shape or color.
