Powder Blue Tang (Acanthurus leucosternon)
Iconic, Vibrant Surgeonfish for Advanced Marine Aquariums
The Powder Blue Tang (Acanthurus leucosternon) is one of the most sought-after surgeonfish in the marine aquarium hobby, known for its electrifying blue body, jet-black face mask, and bold yellow dorsal fin. This species is highly active and thrives in large, established reef aquariums with strong flow and ample swimming space.
Powder Blue Tangs are best kept by experienced aquarists due to their sensitivity to water quality and potential territorial behaviour. Provide a spacious tank with plenty of live rock for grazing, along with a high-quality herbivorous diet rich in marine algae, nori, spirulina, and supplemented frozen foods. When cared for correctly, they become a stunning centrepiece fish with impressive personality and colouration.
Ideal for reef systems, the Powder Blue Tang is an excellent algae grazer and contributes to a balanced, healthy aquarium ecosystem.
