Demon Fish are a species of large predatory fish that live in the rivers and lakes of Kyrat in Far Cry 4. Be careful when dealing with these fish. They can be easily killed by accurate fire or explosives; the only difficulty is finding them, as they are often harder to spot. Demon Fish are based on the real world Goliath Tigerfish (Hydrocynus goliath), a large predatory fish found in Central Africa that is responsible for a number of fatal attacks on people.
