The image is an underwater photograph of a large fish swimming in an aquarium. The fish appears to be an eel, with a long, slender body and a pointed head. It is swimming towards the right side of the image, towards the bottom right corner. The water is dark and murky, and there are several large rocks and plants visible in the background. The rocks are covered in green algae and moss, and some of them are partially submerged in the water. The image is taken from a low angle, looking up at the fish and the rocks.
