n aquarium, seemingly lit by indoor lighting. The water is clear, and the base of the tank is covered with dark gravel. There is a piece of porous rock resting on the gravel, with a gray-colored fish lying on top of it. There's also a piece of driftwood, some small green plant decorations, and a few very small colorful fish visible near the bottom of the tank. Some pinkish-red pellets or small decorations are scattered on the gravel. A water pump is installed. The camera's point of view is at an angle, looking down into the aquarium.
