In the video, we can see a group of fish swimming in the ocean. The fish are yellow and black in color and are of the same species. They are swimming around a coral reef, which is visible in the background. The water is clear and blue, indicating that the location is likely in a tropical area. The fish are moving in a coordinated manner, suggesting that they are part of a school. There are no visible signs of human interference, and the environment appears to be natural and undisturbed.
