This video captures a serene underwater scene where a school of fish is swimming in a large body of water. The water is a deep blue color, and the fish are dark in color, possibly black or navy blue. They are swimming in a coordinated manner, creating a beautiful and calming visual effect. The fish are of various sizes, but all appear to be similar in shape and color. The video is shot from above the water, looking down at the fish, and the camera remains stationary throughout the video. There are no visible landmarks or other objects in the water, just the fish and the water itself.
