The Mekong giant catfish, Pangasianodon Gigas, is a species of catfish which said is the biggest catfish in the world. Watch this guy stay very busy fighting big catfish. As big as the Mekong giant catfish.

This is a huge Goliath Grouper. This guy almost get hurt by its tail. The fish was released, It was not killed. Thank God :)

The man in the video almost pulled out of the boat. He pulling the boat to the fish, lifting as hard as he could, the fish surfaced. "It looked like a barnyard beast, or maybe a shark. No one know how big was that fish......?
