In the video, a man is seen holding a fish over a tank filled with water and other fish. He then drops the fish into the water, and the fish swims away. The man is wearing a white shirt and is standing next to the tank. The fish appears to be a small, silver-colored fish with a yellow tail. The tank is filled with clear water and has a blue border. There are several other fish swimming in the tank, including a large fish with a greenish-brown body. The man seems to be observing the fish as it swims away.
