Whether guppies need lighting depends on their growing environment. If their growing environment has sufficient natural light, there is no need to turn on aquarium lights to supplement lighting. Because too much light is not good for their growth and development, it may lead to their mental tension.

If the guppy grows in an environment that does not receive natural light, the breeder needs to add light to them. Because guppies growing in the wild can receive more natural light, when the light is insufficient in artificial breeding, their body color will become dim. In addition, guppies don't like to eat in dark environment, but when there is enough light, their appetite will increase, so when there is insufficient natural light, breeders need to install aquarium lamps to supplement the light.

LED lamps can be installed to raise guppies. The light of this lamp is close to the sunlight, which can not only promote their hair color, but also improve their activity. However, only white LED lights may not be able to promote hair color, and the colors of guppy are varied. Breeders can add lights of other colors according to the body color of guppy, which can not only promote color improvement, but also enhance the ornamental value of guppy.
