The video captures three fish in murky, grey-green water, likely a pond or lake. Two of the fish are prominently featured in the center and bottom-right of the frame, repeatedly opening and closing their mouths at the water's surface. The fish at the bottom right has its mouth wide open for a prolonged period, revealing its pinkish interior. The fish at the top right also exhibits similar mouth movements. A third fish is partially visible on the left side, swimming slowly below the surface. The scene appears to be outdoors during daytime, with ambient light reflecting off the water. The audible background includes human speech in Mandarin Chinese, consistent with the given location context of Xihu District, China. The fish seem to be engaged in surface activity, possibly feeding or gasping.
