The name "tigerfish" has occasionally been used for species of cichlid in the genus Rhamphochromis. These are large, silver-colored fishes that may have one or two black horizontal lines running the length of the body. These fish are native to Lake Malawi in Africa. They can measure up to 2 meters (6 ft. 7 in.) in length and weigh up to 50 kg (105 lbs.) They also have very sharp teeth that can rip through skin easily; however, they are not known to eat humans. However, according to urbanlegends.com, the goliath tiger "has the somewhat singular distinction of being the only African freshwater fish (excluding the Zambezi shark, which is really a saltwater fish) known to attack humans, and there are several recorded incidents from the Congo River."
