Ecological Risk Screening Summary - Mayaheros amarus (a cichlid, no common name) - Uncertain Risk

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.

Mayaheros amarus is a cichlid native to Isla Mujeres off the Yucatán Peninsula, Mexico. Little information is available about this species. M. amarus has not been reported as introduced outside of its native range, therefore no information is available on potential impacts of an introduction. History of invasiveness is uncertain. This species does not appear to be in trade in the United States or elsewhere. The climate match with the contiguous United States is medium, with the highest match in southern Florida. All states recorded a low score except Florida, which recorded a high score. Due to lack of information about potential negative impacts from introduction, the certainty is low; the overall risk for this species is uncertain.
