The video shows a close-up shot of an aquarium filled with a variety of brightly colored GloFish swimming amidst aquatic plants. The fish come in shades of pink, yellow, green, and blue. They are actively moving around the tank. The aquarium is lit from above, with a dark blue background. The bottom of the tank appears to be covered with gravel and dark plant matter. A dark, thin branch extends horizontally through the frame.
