The video shows a school of many small fish swimming actively in clear, shallow, turquoise-green water. The seabed is visible through the water, consisting of small pebbles or sand. Sunlight refracts through the rippling water surface, creating shimmering light patterns on the bottom. The fish are uniformly small and dark, darting around in various directions. No people or text are visible. The scene suggests a calm, sunny day in a coastal area, specifically Đenovići, Montenegro, as provided by the context.
