It takes 3-4 months for male guppies to grow beautiful tails, and their growth speed is relatively fast. They can mature in about 3-4 months, and their tails will grow beautiful.

The tails of guppy male fish are more ornamental than those of female fish. If breeders want to make their tails look good, they must first prepare enough space for them, so that they can move better and grow their tails better. The second is to ensure that they have enough food and nutrition, so that they can develop their tails better.

The time for guppies to develop color is not fixed. If properly raised, they can develop color about 15 days after birth, and can show particularly obvious color about 30 days after birth. However, if the breeder is inexperienced, it may take about 60 days to appear obvious colors.

If breeders want guppies to develop color, they should be fed more spirulina and bumper shrimp, so that they can develop color better. It is also necessary to keep enough light, so that they can synthesize pigments better. After guppy hair color, breeders should keep the water temperature and water quality stable, so as to avoid the change of their body color caused by environmental fluctuations.
