In this video, we see a person's hand reaching into a fish tank and feeding the fish. The fish are eagerly swimming towards the hand, eager to eat the food. The fish are of various sizes and colors, and they are all swimming in the same direction towards the food. The water in the tank is clear, and we can see the fish's movements and the bubbles they create as they swim. The person's hand is steady as they hold the food, and the fish seem to be enjoying their meal.
