Blue Tangナンヨウハギ

Paracanthurus hepatusLC— Least Concern

The blue tang, also called the palette surgeonfish, is a vivid royal-blue reef fish with a yellow tail and a distinctive black "palette" marking, found across the tropical Indo-Pacific from East Africa to the Great Barrier Reef. It feeds on zooplankton and algae, defends itself with a sharp spine near its tail, and became world-famous as the character Dory in Disney/Pixar's Finding Nemo and Finding Dory.

Did You Know?

  • It hides a sharp spine near the base of its tail and, when fighting, flicks the spine outward and slashes its body sideways at rivals. Source
  • Its body color shifts with its condition, appearing vivid blue when healthy but paling to a whitish hue when sleeping or unwell; at night it wedges itself into a crevice and lies down to sleep. Source
  • It ranks as the 8th most traded aquarium species worldwide, with about 95,000 individuals imported in 2011 alone; captive breeding was long considered difficult until biologist Kevin Barden achieved it for the first time in 2016 after a six-year effort. Source
