In the video, we see a person's hand reaching into a fish tank. The fish tank is filled with water and has several fish swimming around. The person's hand is moving around, and the fish are swimming around it. The fish are of different sizes and colors, and the tank is decorated with plants and rocks. The person's hand is moving slowly, and the fish seem to be curious about it. The water in the tank is clear, and we can see the light reflecting off the fish and the plants.
