The image is an underwater photograph of a blue and green fish swimming over a coral reef. The fish has a long, slender body with a pointed snout and a pointed tail. It is swimming towards the right side of the image, towards the left side. In the background, there are several large, white sea fan-like structures that appear to be coral reefs. The water is clear and blue, and the coral reef is covered in various shades of green and brown. The image is taken from a low angle, looking up at the fish and the sea fan.
