Ecological Risk Screening Summary - Trichomycterus transandianus (a catfish, no common name) - Uncertain Risk

Trichomycterus transandianus is a catfish endemic to the Magdalena River basin in Colombia. It is listed as “Vulnerable” on the IUCN Red List. Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. There has been no documentation of introductions outside of its native range. History of invasiveness is uncertain. T. transandianus has a low climate match throughout the contiguous United States.
