Aggressiveness
In Bengal and Assam, it is known as Boal and Borali respectively. Its common to find huge frogs and fishes inside its stomach, when cut for cooking. It has been claimed that in some areas of Thailand the natives fear the species because of its believed habit of eating small ducks, dogs, and small children. It is thought the Tapah became this aggressive due to natives laying to rest their dead in the water. The catfish would then see this as a ready supply of food.
