- The Oneline Wrasse can be found in various locations around Australia, including the waters around the Great Barrier Reef, the Coral Sea, and coastal areas of New South Wales and Queensland. It is commonly found in the north eastern part of Australia.
- The Oneline Wrasse has a slender body with a blue-green coloration on the upper half and yellowish coloration on the lower half.
- It is a diurnal species, which means it is active during the day and rests at night.
- The Oneline Wrasse feeds on small invertebrates, such as crustaceans, worms, and molluscs. It has a protrusible mouth that it uses to capture its prey.
- During breeding season, males can display intense colours, with bright blue and green patterns.
- The Oneline Wrasse breeds by laying demersal eggs, which means the eggs are deposited directly onto the substrate, such as rocks or coral. The male fish guards the eggs until they hatch. After hatching, the larvae are planktonic, drifting in the water column until they are large enough to settle on the substrate.
- There is limited information on their lifespan, but similar species of wrasse in the Labridae family have been known to live up to 15 years.
