dense gathering of fish swimming in shallow, murky water

dense gathering of fish swimming in shallow, murky water. The fish appear to be mostly grey and silver, with some darker hues mixed in. They are densely packed together, creating a shimmering effect as they move. The water has a greenish tinge, suggesting the presence of algae or other plant life. The bottom of the pond or water body is not clearly visible due to the density of the fish and the murkiness of the water. The camera remains focused on the fish throughout the video. There is also audio of people speaking in the background.
