There are several rocks of different sizes and colors, including shades of gray, brown, and white. There is also a plant with green leaves in the tank. The plant appears to be healthy and well-maintained. The rocks are arranged in a way that creates a natural-looking landscape within the tank. The water is clear, and there are no visible fish or other aquatic creatures in the tank. The lighting in the room reflects off the water, creating a shimmering effect.
