Fun facts

  • The juveniles hide among the branches of Pocillopora corals and barely leave them; the adults range further and graze in groups across the reef slope.
  • On each side of the tail base it carries a retractable spine as sharp as a scalpel, which is where the name surgeonfish comes from.
  • It was first bred in captivity in 2016, after six years of work, to reduce the pressure of the aquarium trade on wild populations.
