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 hastatus is a small catfish with a broad native distribution in South America. C. hastatus has a medium climate match overall with the contiguous United States, with the areas of highest match occurring in Florida and Texas. While C. hastatus is present in the aquarium trade, including within the U.S., no introductions have been reported in the U.S. or elsewhere. Given the existing information on C. hastatus and no known introductions beyond their native range, it is difficult to predict the potential impact if introduced to U.S. waterways. Therefore, the overall risk posed by this species is uncertain.
