The video shows a fish tank with two fish swimming around. The fish are of different sizes and colors. One fish is larger and has a mix of white and brown spots on its body, while the other fish is smaller and has a greenish-yellow body. The tank is well-lit, and the water is clear, allowing for a good view of the fish. The fish are swimming in different directions, sometimes crossing paths and sometimes swimming in the same direction. The larger fish seems to be more active and is seen swimming around the tank more frequently than the smaller fish.
