The video shows a close-up view of a fish tank. The tank is filled with water and has a green border. There are several fish swimming around inside the tank, and they are of different sizes and colors. The fish are moving around in different directions, and some are swimming near the surface while others are near the bottom of the tank. The water is clear, and the lighting in the room reflects off the surface of the water, creating a shimmering effect. The fish appear to be healthy and active, and there are no visible plants or decorations in the tank.
