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.
Nannostomus beckfordi is a small freshwater fish that is native to the Amazon River basin in South America. This species is also popular in the aquarium trade. The history of invasiveness for N. beckfordi is uncertain. No records of introductions were found. The climate match for the contiguous U.S. is low. The results of the climate match indicate that only a very small area of the country may have the necessary climatic conditions to be able to support a sustained population of N. beckfordi. The certainty of assessment is medium. The overall risk assessment category is uncertain.
