This image depicts an aquarium filled with water. The background is a bright blue. In the foreground, there is a tan-colored ceramic tube, partially covered in green algae. To the right of the tube is a moss-covered rock. The substrate is composed of small, reddish-brown pellets. Several aquatic plants are visible, including long, thin green strands and broader-leafed plants. Two small catfish with distinctive markings are present; one is in the mid-ground to the right of the tube, and another is partially visible in the background to the right of the rock. A small, slender fish with a red tail and iridescent blue body is swimming in the upper left portion of the aquarium. The image does not provide any information about the city of Mikhaylovsk, Russia.
