Giant Mekong Catfish has one of the fastest growth rates of any fish and can reach a weight of 200kg/ 440 lb in 5 years and can grow to a length of up to 3m / 10ft and can weigh upwards to 350kg / 770 lbs which makes it on of the heaviest freshwater fish in the world. No one knows for sure which freshwater species grows to be the largest although many speculate that it might be giant freshwater rays that are found in the same waters as the Giant Mekong Catfish and are know to grow over 4 m / 13 ft long. Large Giant Mekong catfish are however as earlier mentioned a rare site these days. Giant Mekong catfish are unlike many other large catfish vegetarians in the wild feeding on the vegetation that can be found in the rivers they live in. Another feature that separates them from many other large catfish is the fact that Giant Mekong Catfish lacks teeth.
