The video shows a body of water with a large number of small fish swimming in it. The fish are moving around in a group, creating a dynamic and lively scene. The water is clear, allowing for a good view of the fish and their movements. The fish appear to be of the same species, with similar size and shape. They are swimming in various directions, some moving towards the camera while others swim away. The water's surface is slightly rippled, indicating a gentle current or movement in the water. There are no other objects or creatures visible in the video, just the fish and the water.
