The image depicts an underwater scene within an aquarium located in Nikolaevo, Bulgaria. A large, dark, weathered stone sculpture of a human-like head with closed eyes and an engraved turtle symbol on its forehead occupies the central background, partially submerged. The water is uniformly illuminated with a deep blue light, highlighting particulate matter. Numerous fish are present: several small, vibrant blue fish with distinct yellow caudal fins swim around the stone head in the mid-water column. Other elongated, darker fish are visible closer to the sandy bottom. In the foreground, a larger, dark-bodied fish with a sleek form and prominent dorsal fins swims horizontally towards the right. The aquarium floor is covered in sand, showing subtle ripple patterns. Occasional warm orange light reflections are visible in the upper right background. No human figures are present in the scene.
