General information

The Bluestreak Cleaner Wrasse, scientifically known as Aspidontus dussumieri, is often mistaken for the true cleaner wrasse due to its similar appearance. However, unlike its peaceful counterpart, the Bluestreak Cleaner Wrasse is known for its aggressive mimicry, a form of deception where it imitates the look and behavior of the cleaner wrasse to take advantage of other fish.

Care

Aspidontus dussumieri can be challenging to keep in captivity due to its specialized feeding habits. In the wild, it feeds on the skin and scales of other fish by deceiving them into thinking it will clean them. In an aquarium setting, it may nip at other fish, causing stress and potential injury. It is essential to monitor tank mates closely and provide a varied diet that includes small meaty foods to discourage this behavior.

Reproduction

Little is known about the reproductive habits of Aspidontus dussumieri in the wild or in captivity. They are not commonly bred in home aquariums, and their aggressive mimicry behavior can complicate social dynamics and breeding efforts.

Symbiosis

The Bluestreak Cleaner Wrasse engages in a unique form of aggressive mimicry, imitating the behavior and appearance of the beneficial cleaner wrasses, such as Labroides dimidiatus. This allows it to approach other fish and feed on their tissues under the guise of providing a cleaning service.

Habitat

Aspidontus dussumieri is found in coral reef environments throughout the Indo-Pacific region. It prefers areas with abundant coral growth where it can easily blend in and approach unsuspecting fish.
