The video shows a close-up view of an aquarium with white gravel at the bottom. There are several fish swimming around, including a red and white fish and a blue and white fish. The fish are seen swimming in different directions, with some coming closer to the camera and others moving away. The aquarium also has a green plant with long leaves, which adds a touch of color to the scene. The water is clear, and the lighting is bright, making the colors of the fish and plant stand out.
