The video shows a large aquarium with a variety of fish swimming around. There is a scuba diver in the tank, and a little girl is standing in front of the aquarium, watching the fish. The fish are of different sizes and colors, and the scuba diver is wearing a wetsuit and a mask. The little girl is wearing a pink shirt and has her hair tied up in a ponytail. The aquarium is well-lit, and the water is clear, allowing for a good view of the fish and the scuba diver.
