The video shows a group of fish swimming in the ocean. The fish are dark in color and have a distinct shape. They are swimming in a coordinated manner, moving in the same direction. The ocean floor is visible in the background, and there are some plants and rocks scattered around. The water is clear, and the lighting is natural, suggesting that the video was taken during the day. The fish appear to be of the same species, and there are at least five of them visible in the frame.
