A fish with a tan, torpedo-shaped body and darker brown tail swims right to left in a glass-sided tank filled with water. The back wall of the tank is a bright, solid blue. The bottom of the tank is covered with a layer of small, dark brown gravel-like material. There are also some dark green objects scattered on the bottom. Two black, rectangular objects are affixed to the back wall of the tank, one near the top, the other closer to the bottom. The camera briefly pans to the left following the fish's movement.
