Care

In the aquarium, Bluestreak Cleaner Wrasses require a well-established environment with plenty of live rock for hiding and foraging. They are best suited for larger systems where they can perform their natural cleaning behaviors. These wrasses are known to be challenging to keep due to their specialized dietary needs, often relying on a steady supply of parasites from other fish. Supplemental feeding with small meaty foods and preparations designed for cleaner wrasses can help sustain them in captivity.

Reproduction

Reproduction of Bluestreak Cleaner Wrasses in home aquariums is rare. In the wild, they exhibit complex mating behaviors and are protogynous hermaphrodites, meaning they can change from female to male during their life cycle. Understanding and replicating the specific conditions needed for breeding is a challenge for even the most experienced aquarists.

Symbiosis

The Bluestreak Cleaner Wrasse is famous for its mutualistic cleaning symbiosis with a wide variety of reef fish. By setting up 'cleaning stations' on the reef, they attract client fish seeking parasite removal. This interaction is beneficial for both parties: the wrasse gains a food source, while the client fish receive health maintenance. This behavior can also be observed in the aquarium, where they may offer cleaning services to tank mates.

Habitat

Native to the Indo-Pacific region, Bluestreak Cleaner Wrasses are found in coral-rich areas and clear lagoons. They prefer environments with strong water movement and are often observed in shallow waters where they can easily access client fish.
