The length of guppies born in ten days is generally only about 1.5-2 cm, because they are just born at this time, and their body shape will not be much different from that when they were born. The size of guppy has a great relationship with the number of pregnant mothers. If the number of pregnant guppy mothers is relatively large, the size of small fish after birth will be smaller. If the number of pregnancies is small, the small fish will be bigger. Although there are some differences in the size of guppies after birth, their differences are not too great, and they will not have much influence on the later growth.
2. How to raise guppies to grow bigger1. Adequate space: If breeders want guppies to grow bigger, they must ensure sufficient space for activities. Although they don't have much demand for living space, and their territorial awareness is not strong. But there is plenty of space, which can make them develop better.
2. Adequate food: Guppies need a lot of nutrition during their growth and development. Breeders need to provide them with enough food and nutrition at the critical stage of their development, so as to make them grow bigger.
3. Environmental stability: Guppies do not have high requirements for the environment, but they are sensitive to environmental changes. Breeders need to keep their living environment stable and comfortable so that they can develop better.
