The video shows a fish tank with several fish swimming around. The fish are of different sizes and colors, and they are swimming in different directions. The tank is well-lit, and the water is clear, allowing for a good view of the fish. The fish are moving around the tank, some swimming near the top while others are near the bottom. The tank appears to be clean and well-maintained, with no visible debris or algae. The fish seem to be healthy and active, and there is no sign of any other objects or creatures in the tank.
