The Powder Blue Tang is a visually stunning saltwater fish, instantly recognizable by its sky-blue body, bold black face mask, and vibrant yellow dorsal fin. Active and energetic, this tang makes a dazzling centerpiece in large reef or fish-only systems but requires stable water quality and ample swimming space.
