1, water temperature: guppy does not require high water temperature, but when they breed, it is best for breeders to keep the water temperature between 23-28 ℃. If the breeder has the conditions, he can install a heating rod to keep the water temperature at about 25 ℃. Because around 25 ℃ is the most comfortable temperature for them to live, it is also of great help to their reproduction.

2. Water quality: When guppy breeds, breeders need to keep the water quality weakly alkaline, and the PH value should be kept between 7.2 and 7.4. When breeding, the water quality should not fluctuate too much, so as to avoid discomfort when breeding.

3. Oxygen: Guppies do not have a high demand for oxygen, but when they breed, it is best for breeders to prepare an oxygen pump for them, so as to ensure that they have enough oxygen when breeding.

Guppy is an oviparous fish that is fertilized in vivo and developed in vivo. When they breed, the male fish chase the female fish first, and in the process of chasing, they will complete mating. After successful mating, guppies do not give birth immediately. Fish eggs will develop in the mother for 20-30 days, and will not be born until they mature. Guppies don't give birth to eggs, but small fish. Small fish can't be fed directly at birth, so it's best to wait for them to move freely before trying to feed.
