Description

The Blue Streak Cleaner Wrasse (Labroides dimidiatus) is a small, peaceful fish well-known for its important role in marine ecosystems as a “cleaner fish.” It has a slender body with a striking blue and black stripe running horizontally from its head to its tail. This species is native to the Indo-Pacific region, where it is often observed cleaning parasites and dead skin off larger fish.

Despite its ecological importance, the Blue Streak Cleaner Wrasse is considered extremely difficult to keep in home aquariums. Its specialized diet in the wild consists primarily of the parasites and dead tissue it picks off other fish, which makes it challenging to feed in captivity. Most specimens struggle to adapt to prepared foods, which is why this species is only recommended for advanced hobbyists or experts with access to live or specialized feeding methods.

While reef-safe, this species needs to be kept in a well-established, mature aquarium. It should not be introduced into tanks with aggressive fish that may not tolerate its cleaning behavior.

Due to the specific feeding needs and difficulty in keeping this species alive long-term, it is classified as Expert Only. The Blue Streak Cleaner Wrasse should be considered a specialty fish for experienced aquarists with extensive knowledge of marine fish care and feeding strategies.

With its peaceful nature and unique cleaning behavior, this species can play a beneficial role in a well-maintained, fish-focused system when cared for by an expert aquarist.
