Otocinclus mimulus is a species of armoured catfish found in small tributaries of the Monday river, itself a tributary of the Paraná river.
Otocinclus mimulus is a Batesian mimic of Corydoras diphyes. C. diphyes is inedible to many species due to its bony armor and so individual O. mimulus that look more similar to C. diphyes are less likely to be eaten by predators like Crenicichla lepidota. O. mimulus is named for its mimicry of C. diphyes.
