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. This additional information will help inform decisions on where, when, and how the species may be used to minimize risks of them becoming invasive
Corydoras ellisae is a small catfish native to the Paraguay River basin in South America. C. ellisae has a medium climate match to the contiguous United States, with the strongest matches occurring in parts of Florida and Gulf of Mexico coastal areas. While the species is known to be in possession of hobbyists outside its native range, it has never been reported in waterways outside of its native range. Without a history of invasiveness, it is difficult to ascertain the impacts that would occur if the species were introduced to the United States. Therefore, the overall risk posed by C. ellisae is uncertain.
