The image is an underwater photograph of a large fish swimming in an aquarium. The fish appears to be a long-finned eel, with a long body and a pointed snout. It is swimming towards the right side of the image, with its head above the water. The water is clear and there are a few small fish visible in the background. The aquarium is filled with rocks and other marine life, and there is a large rock formation visible on the bottom right corner. The image is taken from a low angle, looking up at the fish and the rock formation.
