Interesting Info

  • The Sixline Wrasse, is a small reef wrasse widely distributed across the Indo-Pacific, including the Great Barrier Reef, Coral Sea, Christmas Island, Cocos (Keeling) Islands, and northern parts of Western Australia.
  • It usually grows to 8–10 cm (3–4 in) in length, with maximum recorded sizes of about 12 cm (5 in).
  • The body is violet to reddish-purple with six bright orange horizontal stripes running from head to tail, giving the species its common name.
  • A distinctive black spot is often present at the base of the caudal fin, edged with white or blue, which may serve as a false eyespot to confuse predators.
  • The large orange-red eyes are highly visible and give the fish an alert, watchful appearance.
  • Males and females look very similar, although males may develop slightly more intense colouration during spawning periods.
  • Juveniles resemble adults in pattern but are generally paler with less intense striping, helping them blend into coral habitats until maturity.
  • The Sixline Wrasse is an agile and active swimmer that weaves in and out of coral branches with speed and precision, making it a challenging fish to observe closely.
  • Its diet consists mainly of small benthic invertebrates, including copepods, amphipods, tiny molluscs, and polychaete worms, as well as small crustacean larvae.
  • It plays an important ecological role on reefs by feeding on parasitic organisms, helping keep other reef fish healthy.
  • Like many wrasses, it is thought to be a protogynous hermaphrodite, starting life as a female before some individuals transition to males under social pressures.
  • Spawning typically occurs at dusk in pairs or small groups, with eggs released into the water column to drift with currents until hatching.
  • Its lifespan in the wild is not precisely known but is estimated at around 5–7 years, similar to related small wrasses.
  • The species name hexataenia comes from Greek, meaning “six bands,” in reference to its six bright stripes.
Species Interaction

Aquarium, Snorkeling & Diving

For divers and snorkellers, the Sixline Wrasse is a colourful but elusive species, often seen weaving quickly through coral branches. In the aquarium trade, it is one of the most common wrasses, prized for its vivid striping, hardy nature, and role in controlling pests. However, it is known to be aggressive toward peaceful or smaller tank mates, making it best suited to experienced aquarists.
