Hydrocynus goliath, also known as the goliath tigerfish,
giant tigerfish, or mbenga, is a very large African predatory freshwater fish
in the family Alestidae.
Hydrocynus goliath is found in the Congo River Basin
(including Lualaba River and Lake Upemba), and Lake Tanganyika. A study
published in 2011 revealed several mtDNA clades in this region, suggesting a
higher tigerfish species richness than traditionally recognized. If confirmed,
this would restrict H. goliath to the Congo River Basin. Four additional
species (H. vittatus and three undescribed species) appear to be present in
this Basin, while two (H. vittatus and an undescribed species) appear to be
present in Lake Tanganyika.
