In the video, a person is seen holding a worm over a fish tank. The worm is then dropped into the water, and the fish begin to eat it. The fish are of different sizes and colors, and they swim around the tank, eating the worm. The water in the tank is clear, and the bottom is covered in small rocks and pebbles. The person holding the worm is not visible in the video, but their hand can be seen. The worm is pinkish-brown in color, and it wriggles as it falls into the water. The fish are eager to eat the worm, and they quickly swarm around it. The video captures the natural behavior of the fish as they feed on the worm.
