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.
The slim betta (Betta bellica) is a fish native to Malaysia and Indonesia. It is used in the aquarium trade, but does not appear to be sold in the United States. There is one record of this species being introduced outside of its native range into the Dominican Republic, where it is now established and abundant. No information about impacts, or lack thereof, from its introduction has been reported. Climate match with the United States is low, but since georeferenced locations were not available for all populations the climate match may be underestimated. Due to lack of information about impacts of introduction of B. bellica, the risk is uncertain.
