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 Scrapermouth Mbuna (Labeotropheus trewavasae) is a cichlid (fish) native to Lake Malawi found in Malawi, Mozambique, and Tanzania, Africa. L. trewavasae normally prefers to be in a rocky habitat free of sediment but is also found in the sediment-rich areas too. L. trewavasae eats algae, using its mouth to scrape it off the rocks, sometimes leaving scrape marks on the rocks. The history of invasiveness is uncertain. A specimen was reported in the United States, but it was a part of a museum collection and not a part of a wild established population. There is also no trade information on the numbers of individuals in trade each year. The climate match for the contiguous United States was low with all States having low individual climate scores. The certainty of assessment is low. The overall risk assessment category for Labeotropheus trewavasae is uncertain.
