The video shows a close-up of a fish tank with several fish swimming around. There are two plastic bags hanging from the top of the tank, and the fish are swimming in and out of them. The fish are of different sizes and colors, and the water in the tank is clear. The plastic bags appear to be filled with air and are floating in the water. The fish are actively moving around, and the camera angle changes slightly throughout the video to capture different perspectives of the fish and the bags.
