The video shows a person's hand pointing at a fish in a tank. The fish is swimming around in the water, and the person's hand is moving around, trying to catch the fish's attention. The fish seems to be a small, dark-colored fish with a slender body. The tank is filled with water and some small rocks or pebbles on the bottom. The lighting in the tank is dim, and the water is clear, allowing for a good view of the fish and the person's hand.
