The video captures a group of small to medium-sized fish swimming just below the surface of murky, brown-colored water. Many of the fish are visible with their mouths at or slightly above the water's surface, suggesting they might be gasping for air or feeding on surface particles. The fish appear to be moving slowly in a loose school. The bright reflection on the water indicates it is daytime, likely under sunny conditions. The scene depicts a calm body of water, possibly a pond or lake in Da Lat, Vietnam. There is no visible text.
