Interesting Info
- The Silverstreak Wrasse is a tropical reef fish found across the Indo-Pacific and in northern Australia from Western Australia through the Northern Territory to Queensland, including the Great Barrier Reef and Coral Sea.
- It grows to about 15 cm (6 in) and is slim and fast, zipping over sandy and rubbly areas near corals.
- The body shows shining silvery-blue streaks along the sides, with males usually brighter and more colourful than females.
- Juveniles carry a bold pale stripe from above the eye to the tail base that fades as they mature, a handy clue for young-fish ID.
- It feeds by pecking quickly at the bottom for tiny invertebrates such as small crustaceans, worms, and molluscs.
- Although often seen singly or in pairs, it can form loose groups that graze together across lagoon and reef-flat habitats.
- Like many wrasses, the Silverstreak Wrasse begins life as a female and some individuals later change to males as they grow.
- During breeding, males brighten and perform quick darting displays to court nearby females.
- At night or when startled, it may bury itself in soft sand to hide from predators.
- Its lifespan is short for a reef fish, roughly 3–6 years, which suits its speedy, on-the-go lifestyle.
- Divers and snorkellers can spot it on sunlit reef flats and seagrass edges, where the flashing silver streaks give the species its name.
- Elsewhere in the world it is also known as the Three-ribbon Wrasse, Silverbelly Wrasse, or Lined Rainbowfish.
Species Interaction
Aquarium, Snorkeling & Diving
The Silverstreak Wrasse are popular among marine aquarium enthusiasts due to their striking coloration and active behaviour. However, they are known to be territorial and can be aggressive towards other fish that invade their space. They can be a delight to snorkelers and divers as they are often seen near coral reefs and rocky areas in shallow to moderate depths. With their striking blue-green coloration and vivid stripes, they are easily spotted and can make for great photo opportunities.
