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.
Puntigrus tetrazona, the Tiger Barb, is a small freshwater fish native to Southeast Asia. The species is widely used in the aquarium trade. P. tetrazona has a low climate match with the contiguous United States overall, and Florida was the only State with a medium climate score. P. tetrazona has been introduced to numerous countries outside of its native range and has become established in some of those countries, but no impacts of introduction have been documented. This species has been introduced to the contiguous United States, but all documented populations have failed. It is established in Puerto Rico, a U.S. territory. History of invasiveness is “none documented” due to a lack of information on impacts. Further information is needed to adequately assess the risk this species poses, so certainty of this assessment is low, and the overall risk assessment category is “Uncertain.”
