The video shows a large pink fish swimming in a tank of water. The fish has a long, pointed nose and a small mouth. There are other fish in the tank, but they are not as prominently featured as the pink fish. The water is clear, and there are bubbles visible in the background. The fish swims gracefully through the water, occasionally turning its body and fins. The lighting in the tank highlights the pink color of the fish, making it stand out against the other fish and the background.
