The Mimic otocinclus (Otocinclus mimulus) is a freshwater fish of the family Loricariidae that grows up to 4 cm.
Description
The mimic otocinclus is a small armoured catfish (Loricariidae) from fresh water of the Paraguay basin in South America. The species grows to about 4 cm and has a slender, bony-plated body with a dark longitudinal stripe and a sucker mouth underneath; remarkably it mimics a Corydoras catfish in colour and shape, so predators avoid it. As a calm, social bottom-dweller it rasps algae and biofilm from plants and wood in small groups. The fish is harmless to humans.
