The video shows a fish swimming in the ocean. The fish has a yellow and black body and is seen swimming near the ocean floor, which is covered in rocks and pebbles. The fish appears to be alone in the water, and there are no other fish or marine animals visible in the video. The water is clear, and the lighting suggests that it is daytime. The fish moves smoothly through the water, occasionally turning its body to navigate around the rocks. The video does not contain any human activity or artificial objects, and the focus is solely on the fish and its natural habitat.
