Powder Blue Tang

Powder Blue Tang (Acanthurus leucosternon) is a semi-aggressive species that is reef-safe as it poses no threat to corals or most invertebrates, focusing primarily on algae grazing. This spectacular species displays a brilliant powder blue body with a distinctive white throat patch, black facial mask, and bright yellow dorsal fin that creates one of the most striking color combinations in the tang family, plus the characteristic sharp spine (scalpel) at the base of the tail. The vibrant blue coloration with contrasting markings makes it one of the most sought-after and instantly recognizable tangs in the aquarium trade. It can reach about 9 inches in adult size. Best kept in tanks of at least 100 gallons or more due to their active swimming nature and territorial behavior toward other tangs, with plenty of live rock for grazing, strong water flow, excellent water quality, and special attention to water parameters as this species can be sensitive during acclimation and requires pristine conditions. Its diet should include a mix of marine algae—nori sheets, spirulina, dried seaweed, algae pellets—as well as high-quality herbivore foods and occasional meaty supplements like mysis shrimp, as this primarily herbivorous species requires constant access to plant matter and benefits from varied nutrition to maintain their brilliant powder blue coloration and overall health.
