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.
Gymnocorymbus ternetzi is native to South America and has been introduced to North America and Asia, although introductions in the United States have failed and the status of some Asian introductions remains uncertain. G. ternetzi is popular in the aquarium trade, and at least some introductions are likely aquarium releases and fish farm escapes. Impacts of introductions have not been studied adequately to determine severity. Climate match is highest in Florida and Texas, with medium match overall for the contiguous United States. Overall risk posed by G. ternetzi is uncertain.
