The Goliath Tigerfish (Hydrocynus goliath) is one of the most fearsome freshwater predators in the world, native to the Congo River Basin in Africa. Known for its razor-sharp teeth, muscular build, and unmatched ferocity, this species is a true trophy for monster fish enthusiasts.
At 8–10 cm, these juveniles may seem manageable, but they can grow to a staggering 100–150 cm (40–60 inches) and weigh over 50 kg in the wild. In captivity, expect them to reach 70–90 cm under proper care. Due to their size, speed, and predatory instincts, Goliath Tigerfish require massive aquariums or indoor ponds, making them suitable only for experienced keepers with the right resources.
