Two fish are swimming inside an aquarium. The larger fish, positioned in the foreground, has a dark grey, scaly body with prominent red fins and red eyes. It swims from the right side of the frame towards the left, then slightly turns its head towards the viewer before continuing its path. A smaller, lighter silver-colored fish is visible further back in the tank, generally following the same direction as the larger one. The water in the tank appears clear, and the background behind the aquarium is a light green color. The bottom edge of the tank has a dark, solid structure. No human subjects, text, or specific location cues (other than the provided context of Kebonsari, Indonesia) are visible.
