The small guppies start to change color about 30-45 days after birth, but the time when they start to change color is different with different feeding methods. If breeders can ensure that they live in a comfortable environment and have sufficient food and nutrition, they can develop color about one month after birth. If they grow in a poor environment or have insufficient food and nutrition, it may take about 2 months for them to start changing color.
The newborn guppy is transparent as a whole, with only a little white head. Only after entering the color development period will their body color gradually change. It usually takes 2 months for guppy to develop color. During their color development, breeders need to ensure that they have adequate light, food and nutrition.
2. How to raise guppies with bright colors1. Sufficient light: guppies need more natural light to synthesize pigments, and breeders need to expose them to the sun for 2-3 hours every day. If they can't receive natural light, the breeder needs to turn on the lights for 3-4 hours to ensure that they have enough light.
2. Adequate food: In order to make guppy more colorful, breeders should usually feed them more abundant shrimp, red worms, colorful feed and other foods. Especially during their color development, they need to ensure adequate nutrition.
