Description

Hydrocynus tanzaniae, the blue tigerfish, is a large, predatory fish. It has pronounced dentition similar to those found in Hydrocynus forskahlii.[2] The holotype was nine and a half inches long (247mm),[2] but specimens have been caught by fishermen greater than 27 inches (70 cm) and 25 pounds (11 kg).[3] At a given length, H. tanzaniae has a deeper body than either H. forskahlii or H. vittatus.[4] These fish are a silvery grey color[3] and often have pronounced stripes.[2][3] They often have markings in blue, black, pink, green and red,[3] making them among the more colorful of African tiger fish. Uniquely among the African tiger fish, they have a blue adipose fin[3] (other species have a black adipose fin).
