The video shows a large group of fish swimming underwater. The fish are of different sizes and colors, and they are swimming in different directions. The water is clear, and the sunlight is shining through, creating a beautiful scene. The fish are moving around a large net that is hanging from the surface of the water. The net appears to be made of a mesh-like material and is attached to a rope. The fish are swimming around the net, and some are even swimming inside it. The video captures the natural beauty of the underwater world and the graceful movements of the fish.
