This video captures a serene underwater scene in an aquarium. The focus is on a group of small, slender fish with a silver-gray color and dark spots. They are swimming around a large green leaf that is floating in the water. The leaf has a pointed tip and is attached to a thin stem. The background of the aquarium is dark, creating a contrast with the bright green of the leaf and the shiny scales of the fish. The fish move gracefully, occasionally darting in and out of the frame. The water is clear, and bubbles can be seen rising to the surface, indicating the presence of an air pump or filter.
