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.
Callichthys callichthys is an armored catfish widely distributed across South America. The species is present in the aquarium trade, and aquarium release is the likely source of one or both of two occurrences of C. callichthys in the United States. C. callichthys is not established in the U.S. or elsewhere outside its native range, and no information is available on the impacts of introduction of this species. Climate match to the contiguous U.S. is medium, with Florida and coastal Texas showing the highest matches. Overall risk assessment category for C. callichthys is uncertain.
