The image is a close-up of a fish swimming in an aquarium. The fish is facing towards the right side of the image, with its head slightly tilted upwards. Its body is dark and its fins are visible. The background is blurred, but it appears to be an underwater environment with other fish visible in the distance. The water is a deep blue color and there are small rocks and plants visible at the bottom of the tank. The image is taken from a low angle, looking up at the fish.
