Can guppies only have one baby

One of the first questions people usually ask is, “How do guppies have babies?” When a guppy gives birth, the females will “drop” 2 to 200 baby guppies, called fry, typically in four to six hours. If she is stressed, however, the process to give birth to all the fry can take up to 12 hours. (source)
As you know, guppies can, on average, give birth to up to 200 fries. That is for a mature guppy in perfect condition. However, a first-time female guppy won’t give birth to as many fry as the average number. The number will vary from 20 to 90 fries at once. (source)
In most normal circumstances, the guppy birthing process takes between two and six hours, but if the mother is having difficulty, it can take up to 12 hours for all the fry to be delivered. In some cases, the mother will deliver a few fry and then stop the delivery only to resume in a few days. (source)
A recent study on Trinidadian guppies has shown that females who mate with multiple males produce more grand-offspring than females who have mated with only a single partner. This is an intriguing result from an evolutionary perspective. Oct 21, 2012 (source)
Stress During Pregnancy One of the biggest reasons why guppies die before or during birth is because of very high-stress levels. You see, pregnancy is a very stressful thing for female guppies. When they are pregnant, their stress levels go up naturally, and there is nothing you can do about that. Apr 7, 2022 (source)
Female guppies are usually in labor for between 2 and 8 hours. Labor is usually an uncomplicated affair with the guppy giving birth to between 40 and 80 babies. (source)
Remove the mother immediately after the birth or she’ll eat the babies. It’s natural for the mother to eat her babies, so it’s important to remove her as soon as you can. Use a fish net to scoop the mother from the breeder net or tank, then place her back in her regular habitat. (source)

How long do you keep fry in the breeder box? In general, the babies should be large enough to not fit in mouths of the adult fish before you add them back into your main tank. For livebearer fry, this may be as soon as 4 to 5 weeks. (source)
Male guppies produce higher quality sperm when courting their sisters, which may hinder females’ efforts to reduce inbreeding, according to new research. May 7, 2014 (source)
When they’re born, all guppy fry look the same regardless of gender. There’s simply no way of telling which is male and which is female. As they continue to grow, differences start to appear. These differences are subtle in the beginning, but as growth rate accelerates, they become more and more noticeable. May 23, 2019 (source)
To dispel misinformation and myths once and for all, guppies cannot change sex and are not hermaphrodites. Females need males to fertilize their eggs and produce offspring, but they will also store the males’ sperm several months for when males are not available. Jan 20, 2022 (source)
