Powder Blue Tang (Acanthurus leucosternon)
Bright, bold, and unmistakably beautiful — the Powder Blue Tang is one of the most iconic and sought-after species in the reef aquarium hobby. Its brilliant sky-blue body, jet-black facial mask, and vibrant yellow dorsal fin make it an instant centerpiece in any marine display.
Native to the coral reefs of the Indian Ocean, the Powder Blue Tang is an active swimmer that thrives in large, open aquariums with plenty of live rock for grazing. While peaceful toward most tankmates, it can be territorial toward other tangs, especially those with similar body shapes or coloration.
A steady diet of marine algae, seaweed, and spirulina helps maintain its vivid coloration and overall health. With proper care, this energetic and elegant species will bring dynamic movement and color to your aquarium for years to come.
