Bluestreak Cleaner Wrasse Fact File

? Size: Individuals grow up to 14cm long and weigh up to 170g

? Distribution: This species inhabits coral reefs in the tropics, from the Red Sea and the Indian Ocean all the way to the western Pacific. They are also spread out into Papua New Guinea, Japan, Fiji, and French Polynesia

? Diet: They clean host fish so they may eat the ectoparasites. The degree to which they rely on this method as its main food supply varies. In tidal habitats such as the Great Barrier Reef, they feed on coral

They invite fish to their “cleaning station” by performing a calming up and down movement of their tails. These fish may even clean the inside of larger fish’s mouths and gills

? IUCN Status: Least Concern. There are no major threats known for this species, although it is targeted for the aquarium trade and there are occurring coral habitat degradation in parts of its range
