The video shows a fish tank with a variety of plants and decorations. The tank is illuminated by a string of lights that are placed above it. The plants are of different shapes and sizes, and there are also some decorations that resemble rocks and coral. The water in the tank is clear, and there are no fish visible in the video. The tank is placed near a window, and the natural light coming in from the window highlights the colors of the plants and decorations.
