Realistic water surface scenes, 1-2 adult grass carp (stout, streamlined body, blue-gray on the back, milky white on the abdomen) swim close to the water surface, and when the tail fins slash, there is a pose where the head slightly protrudes out of the water surface, 3-5 green duckweed floats on the water surface, light brown bottom stones can be vaguely seen underwater, sunlight directly hits the water surface to form rippling waves, grass carp scales have natural reflections, the picture has a slight sense of water mist, and the overall atmosphere is close to the real pond ecology.
