Copella nattereri or the spotted tetra is a species of fish in the splashing tetra family found in the upper Amazon basin, as well as the Rio Negro and Orinoco basins.

They grow no more than a few centimeters.

[1] The fish is named in honor of Johann Natterer (1787-1843), who explored South America and collected specimens there for 18 years, including the type specimen of this species along with many others.
