Hydrocynus goliath is a piscivore, feeding on any fish it can overpower, including smaller members of the same species. Their huge, powerful, rigid teeth make them one of the most ferocious predators of the Congo basin, dangerous for the smaller fish they prey on as well as for the hunters who attempt to capture them for sport and for food.
