The image is an underwater photograph of a fish, specifically an angelfish, swimming on a coral reef. The fish has a blue body with black spots on its wings and tail. It has a yellow head and a black stripe running down its back. Its eyes are large and round, and its mouth is slightly open, as if it is looking towards the right side of the image. The background is dark, and the coral reef is covered in small rocks and coral. The colors of the coral and the fish are vibrant and the image is taken from a low angle, looking up at the fish.
