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.
Acnodon normani, Sheep-pacu, is a fish native to the Amazon, Xingu and Tocantins River basins in Brazil. It has not been reported as introduced outside of its native range. Therefore, history of invasiveness is uncertain. This species is present in the aquarium trade, although very few reports were found from U.S.-based retailers. The climate match with the contiguous United States is low with a medium match in southwestern Florida, and a low match in the remainder of the country. Certainty of assessment is low due to lack of information, and the overall risk for this species is Uncertain.
