Ladigesia roloffi, the Sierra Leone dwarf characin, is a species of harmless African tetra that is found in Sierra Leone and Liberia, Africa.[2] L. roloffi is the only member of its genus.[3] The fish was named in honor of German aquarist Erhard Roloff (1903–1980), who collected the type specimen.[4] They are a social species generally living in schools at mid depths and surface level fresh water. It lives for five years. Ninety-seven percent of their natural habitat has been lost.[5]
