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.
The history of invasiveness for Corydoras arcuatus is not documented. A few generalized records of introductions were found but could not be substantiated and no records of impacts were found. This species is present in the international ornamental trade. In 2003, Peru exported over 200,000 individuals. The climate match was medium for southern Florida and low for everywhere else. The certainty of assessment is low. The overall risk assessment category is uncertain.
