This video shows a large group of fish swimming in the ocean. The water is a clear blue color, and the fish are moving in a coordinated manner. The fish are of various sizes and colors, but they all appear to be the same species. The video is shot from above the water, and the fish are swimming in a circular pattern. The sunlight is reflecting off the water's surface, creating a shimmering effect. The fish are moving at a steady pace, and there is no visible sign of any other marine life or objects in the water.
