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.
Giant Rivulus (Anablepsoides hartii) is a killifish native to Caribbean drainages of South America. This species has a medium climate match with the contiguous United States, with the area of highest match located in California. The only known introduction of this species to the United States is in southern California, where it escaped a tropical fish farm and was found in a nearby drainage ditch. Certainty of this assessment is low because no research is available which documents what impacts, if any, A. hartii has had where introduced. Overall risk assessment category is uncertain.
