Well in my opinion grabbing a small dog from a beach, when its not even in the water (they knew there was big catfish there so didnt let the dog in the water) is pretty damn impressive and aggressive lol.
If it was in the water in its territory by its nest id understand its just defending, but just grabbing it off the beach is next level.
Also read some rumors about some smaller children being taken by wels, i believe one of the stories was in England and was talking about a possible 6 to 8 meter long monster, not sure about how true the stories are but it doesnt seem impossible to me.
Anyways super cool fish, love their looks
