Bluestreak Cleaner Wrasse
Also called the blue diesel wrasse or bridled beauty, the bluestreak cleaner wrasse is native to the Indo-Pacific and found at depths of up to 40 metres. It prefers coral rich areas, and lives in social groups made up of one male and multiple females. If the
male dies, the largest of the females will change sex to fulfill his role. Males and females look the same, with a bright blue body often tinged with yellowish white on the front half. A wedge-shaped black stripe runs from the snout to the tip of the tail fin. Bluestreak cleaner wrasse are active during the day, operating established reef cleaning stations where they feed on the parasites and mucus of visiting fish. They are heavily targeted by the aquarium trade, but remain listed as Least Concern on the IUCN Red List.
