 African Tigerfish (Hydrocynus vittatus)


Various species categorized under the Hydrocyanic genus within the Alstead family are commonly known as "tigerfishes" and are highly sought after as game fish, primarily found in rivers and lakes across Africa. These African tigerfishes are recognized for their fierce predatory nature, characterized by distinctive and proportionally large teeth.


One of the most renowned members of the tigerfishes family is the goliath tigerfishes (Hydrocyanic goliath), with the largest recorded specimen weighing an impressive 70 kg (154 pounds). This species inhabits the Congo River system and Lake Tanganyika, holding the title of the largest member in the Alstead family. Another well-known species, simply named the tigerfishes (Hydrocyanic vitiates), is commonly found in the southern Okavango Delta, Zambezi River, Lake Kariba along the Zimbabwe-Zambia border, Kaboom River in Zambia, Carbora Basse in Mozambique, and Joline Dam in South Africa. Both the goliath tigerfishes and its smaller counterpart, the tigerfishes, are indigenous to Africa.


Behavior

Hydrocyanic vitiates is often considered Africa's equivalent to the South American piranha in the world of western game fishing, despite belonging to a distinct zoological family. Similar to piranhas, individual tigerfishes exhibit interlocking razor-sharp teeth, possess streamlined muscular bodies, and display extreme aggression as proficient predators, sometimes hunting in groups. There have been documented instances of African tigerfishes attacking and catching birds in flight.


Cichlids

The term "tigerfishes" has occasionally been used for a cichlid species in the Rhamphochromis genus. These large, silver-colored fish native to Lake Malawi in Africa are recognized for having one or more black lines along their flanks. Similar to other African tigerfishes, they are famous for their prominent teeth and are known to exhibit aggressive behavior towards humans.


Datnioididae

In fishkeeping literature, several Caius species (or Datnioides, depending on the taxonomic authority) have been labeled as "tigerfishes." These large, wide-bodied fish are distinguished by vivid black stripes covering their flanks.


Erythrinid

Occasionally, the term "tigerfishes" has been used for the large South American characins belonging to the Erythrinid family.
