God Damn!

A small, dark-colored fish with a long, slender body swims vertically in an aquarium, moving from the upper left towards the bottom right before disappearing behind a piece of driftwood. The fish then reappears, swimming downwards along the side of the wood, as the camera follows its movement through the water. The setting is a freshwater aquarium with a dark gravel substrate, green aquatic plants, and a piece of driftwood.
