The image is an underwater photograph of a large group of fish swimming in an aquarium. The water is clear and blue, and the rocks on the right side of the image are dark and jagged. The fish are of various sizes and colors, including yellow, orange, and white. They are swimming around the rocks, and some are swimming towards the bottom of the tank. In the background, there is a large rock formation that appears to be part of a larger structure. The image is taken from a low angle, looking up at the fish and the surrounding water. The overall mood of the photograph is peaceful and serene.
