Fin's Fish Guide
The Cleaner mimic (Aspidontus taeniatus) is a saltwater fish of the family Blenniidae that grows up to 12 cm.
Description
The false cleanerfish is a blenny (Blenniidae) from the Indo-West Pacific and a textbook example of mimicry. The species reaches about 11 cm and mimics the cleaner wrasse Labroides dimidiatus in colour (blue with a black lateral stripe), shape and even swimming behaviour. Other fishes thus allow it to approach as if they will be cleaned, whereupon the false cleanerfish boldly nips off bits of fin, skin and scales. It lives singly or in small groups on lagoon and seaward reefs, often in empty worm tubes or narrow holes. Through this deception the species is a classic example of aggressive mimicry.
