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.
Pethia nigrofasciata is a freshwater fish native to Sri Lanka. It is also present in the aquarium industry. The history of invasiveness for P. nigrofasciata is not documented. There were records of introductions that resulted in established populations but no records of any demonstrated ecological impacts. The climate match is low. The results indicate that most of the country would not be able to support a population of P. nigrofasciata but there are small areas of Florida where the climate might be suitable. The certainty of assessment is medium. The overall risk assessment category is uncertain.
