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)
Female Guppy Hiding Hiding between plants or staying in a corner of the tank is another sign that your female guppy fish is in labor and ready to give birth. This is not a normal behavior of guppies. So it is easy to spot. Just before giving birth, she will separate herself from the rest. (source)
A guppy that is about to deliver may experience contractions as she prepares to push her fry out of her body. Contractions may cause your fish to look like she is trembling or shuddering. This is usually a sign that your fish is about to go into labor. May 26, 2021 (source)
Guppies don’t give birth to all their babies at once. That’s because they don’t lay eggs like other fish. So, they have to give birth to one fry at a time. That is why they need more time for breeding than other fish. (source)
Baby guppies are in danger as soon as their born, so it’s important to keep them safe. Keep them separated from the adult guppies, or at least give them hiding spots in the tank to avoid being eaten. Feed them often, keep them in warm water, and give them live food to allow them to grow quickly. (source)
It’s not uncommon for guppies to die after giving birth, and in some cases, even during birth. Unfortunately, there are many reasons that this can happen, and some of them are beyond your control. However, in some cases, you can reduce the chance of your fish dying after giving birth. (source)

It is not normal for guppies to lay on the bottom of the tank. In my experience, there are a number of reasons guppies lay on the bottom of the tank and these include illness, stress, and poor water quality. Pregnant females may also lay on the bottom of the tank prior to giving birth. (source)
Guppies are livebearers, which means, they give birth to live fry. The female guppy gives birth to 20-60 fry at a time. They usually give birth once every 30 days, until they become 2-2.5 years old. Usually, the female guppy will hide, when she is ready to drop the fry. (source)
