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. This additional information will help inform decisions on where, when, and how the species may be used to minimize risks of them becoming invasive.
The Spotted Headstander (Chilodus punctatus) is a species of omnivorous fish native to river basins in northern South America, including the Amazon River basin. The history of invasiveness for Chilodus punctatus is uncertain. One report of an introduction was found but could not be verified as an introduction to the wild and the record had no detailed information. C. punctatus has been in trade in the United States since at least 1992 with no introductions in the wild. There are records of this species being in trade in Singapore and China as well but no information on the volume of trade. The climate match is low; the Climate 6 score was 0.003. Florida had a high climate match at the state level. The certainty of assessment is medium. The overall risk assessment category is uncertain.
