Carpet Wrasse

Interesting Info

• The Carpet Wrasse, is widely distributed across northern Australia, from Western Australia through the Northern Territory to Queensland.
• Its elongated body and strong fins allow it to dart quickly among rocks and rubble.
• Juveniles are among the most unusual-looking wrasses, with two long, trailing dorsal fin filaments and a mottled black-and-white pattern that mimics drifting algae or crinoids, helping them avoid predators.
• Adults lose the ornate dorsal fins but develop a striking pattern of alternating dark brown to green bars with white markings, giving them a “carpet-like” appearance across the reef floor.
• They are known for their remarkable behaviour of lifting and flipping over rocks, coral rubble, and even seaweed mats in search of prey—hence the name “Rockmover Wrasse.” This behaviour can expose hidden invertebrates and even provide feeding opportunities for other reef fish nearby.
• Their diet includes crabs, shrimps, molluscs, brittle stars, worms, and other small reef animals, which they crush with strong jaws and teeth.
• Carpet Wrasses are protogynous hermaphrodites, starting life as females before some transform into dominant, brightly patterned males.
• They are most active during the day, often foraging alone or in pairs across sandy patches and rubble zones near coral reefs. At night, they wedge themselves under rocks or bury partially in sand for protection.
• Spawning occurs in pairs in the water column, with eggs and sperm released into open water where the fertilised eggs drift until hatching. Juveniles settle in shallower lagoons and rubble fields before moving to deeper reefs as adults.
• Their lifespan is estimated at around 7–10 years in the wild, depending on predation and habitat stability.
• They are an important mid-level predator on reefs, helping control invertebrate populations and creating microhabitats for other reef species when they overturn rocks.
