It usually takes 3-6 months for guppies to grow up, and they grow faster. As long as they are properly raised, they can soon mature. However, how long it takes to become an adult depends on the way and environment of feeding. Under the condition of normal feeding, as long as they can live in a comfortable environment and have enough food, they can mature within 3-4 months of birth.

If they live in a poor environment and have insufficient food and nutrition, it will take them longer to mature, about 4-6 months. If breeders want to make them grow faster, they must ensure that their living environment is comfortable and provide them with adequate nutrition.

Guppies are small tropical fish, and their life span is not particularly long. Under normal circumstances, artificially raised guppies can only live for 2-3 years. However, guppies growing in the wild have a longer life span, probably more than 3 years.

If breeders want guppy to live longer, they must first ensure their physical fitness and feed them more nutritious food at ordinary times. The second is to reduce the number of times they reproduce, because the frequency of reproduction is too high, which will also consume their life span. Finally, check their bodies regularly to avoid getting sick.
