A large sturgeon-like fish swims gracefully in an aquarium. The fish has a long, slender body with a light, almost fluorescent green underside and a darker blue-grey back. Its elongated snout is prominent, and it has a long, pointed tail fin. It swims close to the water's surface, with its reflection clearly visible on the water. Smaller fish are also visible in the background and near the main fish. The aquarium tank features various rocky formations and decorations, with green and dark brown hues, illuminated by underwater lighting. The environment outside the tank appears dark, suggesting an indoor setting like a public aquarium. Reflections of onlookers, including parts of their faces and bodies, are faintly visible on the glass of the tank, indicating people are observing the fish. No discernible text is visible.
