Whether guppy fry grow fast is mainly determined by whether the water body is wide, whether the food is sufficient, whether the water temperature is appropriate, and whether the water quality is up to standard. The bigger the water, the faster the fry will grow.
Feeding more high-protein and nutritious food can make small fish grow rapidly. For example, newly hatched shrimp eggs, shelled shrimp, cooked egg yolk and egg white and other foods can provide high nutrition and protein for small fish fry to help them grow healthily. Feeding a small amount of food regularly and many times a day can also make the fry grow better. In addition, the water temperature of about 25 degrees and clean water are most suitable for the growth of guppies.
It takes about three to six months for guppy fry to grow up into adult fish. When the fry grows up to more than one month, the sex can be identified. When the fry grows up to three or four months, the sex can be mated and reproduced. The mature time of small fish is closely related to the water temperature and feeding conditions. The sign of sexual maturity of male fish is that the genitals become pointed, and the sign of maturity of female fish is that the abdomen appears black fetal spots. Appropriate water temperature, clean water quality and regular feeding can help small fish grow up faster and healthier.
