A yellow boxfish, identifiable by its distinctive horn-like protrusions above its eyes and on its lower rear body, swims slowly from left to right across an aquarium tank. The fish is bright yellow with numerous blue and orange spots across its body. In the background, a dark-colored fish is partially visible. The bottom of the tank is covered in light-colored sand or gravel, and the background features rocks and corals with patches of green and reddish algae. The water is clear, and the scene depicts marine life in an aquatic exhibit, likely within an aquarium in Kogalym, Russia.
