The image is a close-up of a round window with a greenish-blue tint. Through the window, we can see a small fish swimming in the water. The fish appears to be a pufferfish, with a small body and fins. The water is a light blue-green color and has a textured surface with small bumps and ridges. The background is dark, making the fish stand out even more. The window is framed by a black frame, and the overall mood of the image is peaceful and serene.
