Ecological Risk Screening Summary - Astyanax leopoldi (a tetra, 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.

Astyanax leopoldi is a tetra fish native to the northern South American countries of French Guiana and Brazil in the Approuague and Oyapock River basins. Limited information exists on the biology, ecology, and distribution of this species. Much of what is reported relates to the species’ descriptive attributes relative to other species. The species is abundant where it occurs, indicating a gregarious nature, but it has not been reported beyond its native range. Current trade status within the United States is unclear. Review of several online retail sites found no specimens currently available for purchase. The species is believed to have potential for future aquaculture. Overall climate match within the contiguous United States is low; with all states matching low. Overall risk of Astyanax leopoldi is uncertain.
