Common name: Seagrass wrasse

General information

The Bluestreak Cleaner Wrasse, scientifically known as Labroides dimidiatus, is a captivating and beneficial species for marine aquariums. This small, elongated fish is easily recognized by its striking blue and black horizontal stripes that run the length of its body. In the wild, these cleaner wrasses play a crucial role in maintaining the health of other fish by removing parasites and dead skin.

Care

In the aquarium, Bluestreak Cleaner Wrasses require a well-established environment with plenty of live rock for hiding and grazing. They are best suited for larger systems where they can establish a cleaning station to service other fish. It's important to note that these wrasses have a specialized diet in the wild, feeding on parasites and mucus of other fish, which can be challenging to replicate in captivity. Offering a varied diet including small meaty foods and live or frozen fare can help meet their nutritional needs.

Reproduction

Reproduction of Bluestreak Cleaner Wrasses in home aquariums is rare. In the wild, they are known to form harems consisting of one male and several females. If the dominant male perishes, the largest female will change sex to take over the role.

Symbiosis

The Bluestreak Cleaner Wrasse is renowned for its symbiotic relationship with a wide variety of fish species. By setting up cleaning stations on coral reefs, they provide a service by removing parasites and dead tissue from client fish. This mutualistic interaction benefits both parties; the wrasse receives a steady food source, while the client fish gain health benefits.

Habitat

Native to the Indo-Pacific region, Bluestreak Cleaner Wrasses are found in coral-rich areas of lagoons and outer reefs. They prefer clear, shallow waters where they can easily access client fish for cleaning.
