The video shows a fish tank with several fish swimming around. The fish are of different sizes and colors, including blue and white. The tank is decorated with green plants and brown driftwood, creating a natural habitat for the fish. The water is clear, and bubbles can be seen rising to the surface. The fish are actively swimming, some darting quickly while others glide slowly through the water. The lighting in the tank highlights the vibrant colors of the fish and the greenery.
