In the video, a man is seen holding a piece of food in his hand and dropping it into a tank of water. The tank is filled with small fish that quickly swarm around the food, eagerly eating it. The man's hand is visible in the frame, and he appears to be wearing a watch. The fish are small and numerous, and they move quickly in the water. The tank is made of clear glass, allowing for a clear view of the fish and the man's hand. The water is clean and well-maintained, and the fish seem to be healthy. The man drops the food several times, each time causing the fish to swarm around it. The video captures the interaction between the man and the fish, as well as the movement and behavior of the fish in the tank.
