What kind of lamp is the best for colorful fairy fish depends on what kind of environment they live in. If the environment in which they live can receive natural light and the light is sufficient, the breeder does not need to turn on the lights for them. Because like humans, they all rest at night. If they live in an environment with natural light, but the light is not enough, the breeder can choose a 10-watt incandescent lamp to replenish the light. If they live in an environment that cannot receive natural light, it is best for the breeder to prepare an LED lamp to supplement the light. The color of the lamp can be chosen according to the body color of the fish, and it is generally warm white with blue or green.

How long do colorful fairy fish turn on the lights in a day depends on whether they can receive natural light. If they can receive natural light, but it is not enough, the breeder can turn on the lights in the evening and turn off the lights at 9-10 pm.

If they can't receive natural light, they need to turn on the lights for about 8 hours every day. But they don't like too strong light. If the light is too strong, it is best to cover it with black veil. But the light should not be too soft, otherwise the illumination effect will become worse.
