In the video, a person is seen using a small brush to paint a fish. The brush is dipped in orange paint, and the person carefully applies it to the fish's body. The fish is held in place by the person's other hand, ensuring that the paint is applied evenly. The person's movements are precise and deliberate, indicating that they are experienced in this task. The fish appears to be a small, freshwater species, and the orange paint stands out against its natural color. The background is blurred, but it appears to be a workshop or studio setting.
