The video shows a large fish swimming in a tank of water. The fish is silver in color and has a long body with a pointed nose. It is swimming near the surface of the water, where a person's hand is visible. The person is holding a plastic bag and appears to be feeding the fish. The fish is eagerly eating the food from the bag. The water in the tank is clear, and there are other smaller fish swimming around the larger fish. The background is not visible, but the focus is on the interaction between the person and the fish.
