The image is a close-up of a catfish swimming in an aquarium. The catfish is facing towards the right side of the image, with its mouth slightly open. Its body is a light grey color with a yellow stripe running down its back. Its eyes are large and round, and its mouth is slightly open, as if it is about to take a bite out of something. The background is dark, and there are rocks and other aquatic plants visible in the water. The image is taken from a low angle, looking up at the catfish.
