In the video, there is a large aquarium filled with water and a variety of fish. The fish are swimming around in the water, and a person's hand is seen holding a piece of food, which they drop into the water. The fish quickly swarm around the food, creating a feeding frenzy. The aquarium is well-lit, and the water is clear, allowing for a good view of the fish and their movements. The person's hand is visible for a few moments as they hold the food, but they do not come into the frame much. The fish are of various sizes and colors, and they all seem to be enjoying the food that has been dropped into the water.
