The video shows a close-up of a fish tank with several fish swimming around. The fish are of different sizes and colors, with some having orange and black stripes, while others are more solid in color. The tank is filled with water and has a greenish hue, possibly due to the lighting or the plants inside. The fish are seen swimming around the tank, some near the surface and others near the bottom. The person filming the video is pointing at the fish, possibly to draw attention to a specific one.
