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.
T. tholloni is a benthopelagic cichlid fish native to Central Africa. It has not been documented outside its native range. The species has a low climate match in the continental United States. Because T. tholloni has no history of invasiveness, it is currently impossible to know what impacts T. tholloni might have if introduced to the US. Overall risk of this species is uncertain.
