The image shows a group of fish swimming in an aquarium. There are three fish visible in the image, two of which are in the foreground and one in the background. The fish in the center of the image is a large, dark-colored fish with a pointed snout and sharp teeth. It appears to be a catfish, with a long, slender body and pointed fins. The other two fish are smaller and have a similar shape and size. The aquarium is filled with green water and there are small rocks and pebbles visible at the bottom. The background is slightly blurred, but it seems to be an underwater environment.
