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.
Penang betta (Betta pugnax) is a fish native to Thailand, Malaysia, Indonesia, Singapore, Cambodia and Vietnam. It is sold in the aquarium trade, including in the United States. B. pugnax has been introduced to two locations outside of its native range. One population is established in Guam, while the status of the population in the Philippines is unknown. No information about impacts, or lack thereof, of its introduction has been reported. The climate match with the contiguous United States is low with small areas of medium match in southeastern Florida, western Florida, and southern Louisiana. Due to lack of information about the impacts of introduction, the risk for B. pugnax is uncertain.
