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.
The Black Neon Tetra (Hyphessobrycon herbertaxelrodi) is a South American fish that is native to the Paraguay River basin in Brazil. The history of invasiveness is uncertain. It has not been reported as introduced or established in the wild anywhere in the world. It has been recorded in the United States, but all those records were from pet stores or fish collections. This species is found readily in the aquarium trade. The overall climate match for the contiguous United States was low. Most of the contiguous United States had a low match but southern Florida had a medium to high match and southern Texas had a medium match. The certainty of assessment is low. The overall risk assessment category is uncertain.
