The video shows a fish tank with a clear glass wall. Inside the tank, there are several fish of different sizes and colors. The fish are swimming around the tank, some near the surface and others near the bottom. There is also a piece of driftwood in the tank, which the fish swim around and under. The water is clear, and the lighting in the tank highlights the colors of the fish. The fish appear to be healthy and active, and the tank is well-maintained.
