  • The neon tetra (Paracheirodon innesi) is a freshwater fish of the characin family (family Characidae) of order Characiformes. The type species of its genus, it is native to blackwater or clearwater streams in southeastern Colombia, eastern Peru, and western Brazil, including the tributaries of the Solimões. Its bright colouring makes the fish visible to conspecifics in the dark blackwater streams, and is also the main reason for its popularity as a tropical fish.
