Six-line Wrasse

By | Last Updated : 27th May 2020

Six-line wrasse is a marine ray-finned fish species, belonging to the Labridae family, indigenous to the Indo-Pacific belt.  Mostly found in the coral reefs, this beautiful fish gets its name because of the six orange stripes running along its body. Pieter Bleeker, a Dutch ichthyologist, described it formally for the first time in 1857 as Cheilinus hexataenia. In certain parts of Thailand, the six-line wrasse is often collected by sea gypsies as their source of food.

Important Things to Know For Fish Keepers

  • Six-line wrasses are known to disappear for some time and hide under the sand or other substrates. If you find your fish missing for long, and cannot spot them inside the tank, check outside, as they are excellent jumpers and can dive out in no time.
  • Keeping their jumping skills in mind, make sure to attach a lid to the tank.
  • Check the live rocks and plants in the aquarium and make sure they are devoid of algae or pests like the bristle worms. This is because, the six-line wrasse often acts as a cleaner fish, consuming the pests and parasites present thriving on the substrates.


Q. Is the six-line wrasse reef-safe? 

The six-line wrasse is reef safe and does not eat corals and other invertebrates present.

Q. How does the six-line wrasse sleep?
