Introduction to Powder Blue Tang

Powder Blue Tang teaches Territorial Harmony by holding a grazing patch it will defend hard, while joining shoals of other surgeonfish when a territory needs to be crossed rather than fought over.

How to identify a Powder Blue Tang

  • Powder-blue body with a black face and a white throat patch
  • Bright yellow dorsal fin running the length of the back
  • White scalpel spine at the tail base, set off by yellow
  • Reaches about 23 cm, compact for a surgeonfish

Why Powder Blue Tang are interesting

  • It grazes filamentous algae continuously through daylight hours.
  • It is among the more aggressive surgeonfishes toward its own kind.
  • Groups sometimes shoal together to feed inside damselfish territories that no single fish could enter.
  • It occurs across the Indian Ocean, from East Africa to Indonesia.
  • Constant grazing keeps fast-growing algae from smothering live coral.

Why this diet?

Almost entirely algae: fine filamentous turf cropped from bare rock and dead coral with rows of small, closely set teeth.

06

Activity, rest, and lifespan

Powder Blue Tangs graze by day and settle into reef crevices at night, losing much of their colour intensity until morning.

Wild powder blue tangs are reported to live about five years on Indian Ocean reefs, where they graze algae and defend feeding territories.

07

Powder Blue Tang reproduction

Pairs or groups rise off the reef to release eggs and sperm into open water, and the parents give no further care. The larvae drift in the plankton for several weeks before settling on shallow reef as small juveniles.

Males and females look alike, with males often slightly larger. Appearance carries no sex signal because the display is territorial rather than reproductive.

08

Predators, threats, and defense

Groupers, jacks and reef sharks. Its answer is the surge zone itself, plus a tail blade that makes it a costly mouthful.

09
