The video shows a group of fish swimming in an aquarium. The fish are small and have white bodies with red stripes. They are swimming around the green plants that are in the aquarium. The plants are long and thin, and they sway gently in the water. The fish move gracefully through the water, sometimes swimming in groups and other times swimming alone. The aquarium is well-lit, and the water is clear, allowing for a good view of the fish and plants.
