Corydoras narcissus, commonly known as the long nosed arched cory, is a species of freshwater ray-finned fish belonging to the subfamily Corydoradinae, the corys, of the family Callichthyidae, the armoured catfishes. This catfish is found in the Madeira and Purus river basins in Amazonian Brazil. It has a longer, more concave ("saddle-shaped") nose, but its color pattern resembles that also seen in a few other Corydoras species (for example, C. arcuatus, C. bethanae, C. granti and C. urucu) from the western Amazon basin, as well as Brachyrhamdia thayeria; they all have spiny fins with a (to humans) painful but not dangerous venom and their similarity is an example of Müllerian mimicry.
