The video shows a large fish swimming in a tank. The fish is moving around the tank, and the camera follows its movements. The tank appears to be in a public space, as there are people walking by in the background. The fish is the main focus of the video, and it is swimming near the surface of the water. The lighting in the tank is bright, and the water is clear, allowing for a good view of the fish. The fish has a sleek body and appears to be healthy. There are no other fish visible in the tank, and the background is blurred, but it seems to be an indoor setting with artificial lighting.
