Guppies don't have high requirements for the color of lights, and they don't have any special favorite colors. When breeders choose lights, they can choose some LED lights that are similar to natural lights to supplement them with light.

Although they don't have too high requirements for the color of lights, they have various body colors and complex colors. When choosing aquarium lamps, breeders can first choose a white LED lamp, and then add other colors according to the guppy's own body color. This can not only promote their hair color, but also enhance their ornamental value.

Guppies turn on the lights for 2-4 hours a day, although they are tropical fish and can receive more natural light. But when they turn on the lights, they will become more excited and have a higher amount of activity. So even during the day, breeders can't turn on the lights for too long. If they live in an environment that cannot receive natural light, they can turn on the lights for a longer time, and they can turn on the lights for 3-5 hours every day.

Guppies can choose to turn on the lights when feeding, because they prefer to eat in a well-lit environment, and well-lit can also increase their activity.
