The video shows a large catfish swimming in a fish tank with several other fish. The catfish is white with long barbels and is swimming around the tank, occasionally coming close to the camera. The other fish in the tank are smaller and have orange and grey coloring. The water in the tank is clear, and the bottom is covered in sand. The catfish seems to be the dominant fish in the tank, as it moves around freely without any other fish getting in its way.
