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.
Caridina propinqua is a small freshwater shrimp native to Asia. This species is in the aquarium trade; however, it has never been reported as introduced or established outside of its native range. C. propinqua has a low climate match with the United States, with medium to high climate match scores occurring in Florida. More information is needed to assess the risk this species poses, so certainty of this assessment is low, and the overall risk assessment category is uncertain.
