Ecological Risk Screening Summary - Glass Knifefish (Eigenmannia virescens) - Uncertain Risk

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.

Eigenmannia virescens is widespread east of the Andes in South America, with the native range extending from the Orinoco River basin in Columbia and Venezuela to the La Plata River basin in Argentina. E. virescens has a medium climate match in the United States. The species is listed on the websites of several U.S.-based aquarium suppliers, but no websites were actively selling the species currently. No introductions have been reported, and without information on introductions or establishments outside of its native range, the potential impacts of establishment of Eigenmannia virescens in the contiguous United States are impossible to discern. The overall risk of this species is uncertain.
