Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
Paracheirodon innesi is a small freshwater fish that is native to northern South America. This species is reported to be very popular in the aquarium trade. The history of invasiveness for P. innesi is not documented. There were a few records of introductions found, but detailed information on the establishment of populations or impacts was lacking in most cases. The climate match for the contiguous U.S. is low. The climate match indicates that this species requires a tropical climate and that there would be virtually no areas in the contiguous U.S. with a climate that could support the establishment of a population of P. innesi. The certainty of assessment is medium. The overall risk assessment category is uncertain.
