The bluestreak cleaner wrasse is a small carnivorous fish that is known for its symbiotic relationship with bigger fishes in the seas and oceans. These fish live in tropical waters and thrive in a reefy habitat.
These small fish belong to the Labroides family which includes the Hawaiian cleaner wrasse (Labroides phthirophagus) and the Bicolor cleaner wrasse (Labroides bicolor) among others.
Like their relative species, bluestreaks eat parasites and dead tissues from the skin of larger fishes in a relationship that is mutual in nature, as the bigger fish provide them with protection from predators in exchange for the cleaning service.
Wrasses are a great addition to aquarists as they are one of the best ways to keep your tank clean due to them only eating parasites, worms, and other harmful pests and insects that cause harm to the other fish in the tank.
Another factor adding to them thriving in tanks and aquariums is that other bigger fish are usually tolerant of them and will not attack or bully them thanks to their usefulness!

Another species, the bluestreak fangblenny, will imitate juvenile cleaner wrasse to get closer to other fish and take advantage of their feeding habits.
Unlike other cleaner species like the cleaner shrimp, wrasses do not harass corals which makes them great for reef tanks that require a cleaner species.
Bluestreak wrasses are hermaphrodites, meaning they have the reproductive organs of both males and females.
Why are they called bluestreak cleaner wrasses?
