Powder Blue Tang
Acanthurus leucosternon
The Powder Blue Tang is a bright Indo-Pacific surgeonfish prized in the aquarium trade, not a typical sport fish. It grazes on algae over reefs and is highly territorial, especially around other tangs and similar-shaped fish.

Identification points
- Powder-blue body with a vivid white face and chest
- Black dorsal fin margin and bright yellow caudal fin
- Oval tang profile with a visible scalpel spine at the tail base
Habitat
Shallow coral and rocky reef slopes, lagoon edges, and surge-exposed outer reef habitats; usually found over hard substrate rich in turf algae.
Bait notes
Not a standard angling target. In captivity it accepts marine algae, nori, Spirulina-based foods, and herbivore pellets; hook-and-line bait guidance is generally not applicable.
Behavior
Primarily an algal grazer that feeds during daylight and defends feeding territories. It is active, fast-swimming, and can be aggressive toward other surgeonfishes.
Caution
Has a sharp scalpel-like spine at the tail base that can cut deeply. As a reef-associated ornamental species, it is not a food fish and should not be considered for consumption.
Fishing notes
Rarely or not intentionally fished with rod and reel; when collected, it is typically captured for the aquarium trade using nets or reef collection methods. Best handled with minimal stress and strong aeration.
