The image shows a large rock formation in an aquarium. The rock formation is made up of multiple large boulders of different sizes and shapes, with some larger boulders on the left side and smaller ones on the right side. The boulders are arranged in a way that they form a tower-like structure, with the largest boulder at the top and the smallest at the bottom. There are also some small plants and rocks scattered throughout the formation. The background is a plain white wall, and there is a wooden panel on the top left corner of the image. The aquarium appears to be empty, with no other objects or decorations visible.
