guppy hair color time is not fixed, but mainly concentrated in the growth stage. Generally speaking, it takes 30 to 40 days for guppies to start coloring from birth. If it is a fast-growing fish, when they grow to about 30 days, the body color will change. The slower growth rate of fish, the latest to 45 days before entering the color stage. If there is no outside intervention, the color development period of fish will last about 60 days. About the time the fish reach adulthood, their body color stabilizes.
1. Temperature: The color of guppy mainly depends on the photoreceptor cells in the scales, and warm environment can improve cell activity. If you want the fish to develop color quickly, you can raise the temperature appropriately. When the temperature is about 28 C, it is most conducive to the color development of fish.
2. Light: Light is very important for tropical fish. But also is beneficial to promoting the hair color of guppies under the condition of sufficient light. And it's better for fish to receive sunlight than light. But the light time can not be too long, otherwise it will be counterproductive. Generally speaking, it is most suitable for fish to receive 6 to 8 hours of light every day.
