One adult and other baby guppies eat another baby guppy. This is common behavior of this little fishes.
Toward the end of the gestation period, may choose to move the female into a birthing tank to protect the fry when they are born. A stressed or hungry female may eat her own fry, and guppy fry are a delicacy to many other fish. If a breeder has been able to keep track of the dates of the gestation period, it can be easy to know when to move the female to a birthing tank. However, it should be noted that doing so can also cause stress that might harm the parent or fry. When the female is ready to , she may grow still and slow in the tank or seek out a solitary spot, but these are not always reliable indicators of the impending birth. It may take a few hours for the female to drop all the fry, and one drop can have as few as two to as many as 200 fry at once, although the average is for a female to give birth to 30-60 baby guppies with each pregnancy.
Water quality has a lot to do with how well and how quickly your baby guppies develop. Fish waste creates nitrates, and when nitrates build up (indicating too many fish in the space) the guppies’ growth slows down. To keep the babies growing, change out about a third of the water each week. This removes the nitrates and gives a boost to guppy growth. If you’re ambitious you can replace about 10 percent of the water every day, as some breeders do, but your guppies will do fine with weekly changes.

First off, get her away from other fish. As you now know, adult guppy fish eat baby guppy fish, so if your pregnant guppy drops her fry in a tank with other adult guppies, there is little hope unless you have a LOT of live plants and hiding spots.You may notice another good cause for your pregnant guppy to hide: other fish may be chasing her. It is quite common for guppy tank mates to chase a female in labor around the tank. This behavior is caused by hormones that the mother guppy gives off when she goes into labor. Other guppies can sense these hormones. As I mentioned before, adult guppies eat baby guppies, so many adult guppies may have learned over time to associate those particular hormones with snack time. It is not uncommon for some of the meaner guppy fish (usually other females) to actually peck at the pregnant female- as if trying to force her into delivery. This is just another reason why it is important to let your mamma guppy have her very own private space when she is in labor. (Knowing about other really helps with other fish.)This is my strategy for guppy births: I use a breeder box that has two main compartments; an upper compartment where the mamma guppy goes and a lower compartment where the guppy fry drop down into once born. The floor of the upper compartment is shaped like a “V” with a slit down the very bottom. The slit is too small for the mamma guppy to go through, but it is perfect for baby guppies. You see, when guppy fry are born their swim bladders are not filled with air yet, so unless they swim really hard they will just sink down to the bottom. That is why the “V” shape is great because the newly born baby guppy fish will slide down the slope to the opening and fall through to their own little area.Baby guppies can be fed newly hatched brine shrimp, newly hatched daphnia, or they can be feddry food. Several fish food companies make dried fry food for livebearing fish and you can findthese online or at your pet store. I've successfully raised many baby guppies to adulthood usingbaby dried fish food, however, you are likely to get better growth of your guppy fry if you feedthem live food as well as the dried food. Don't try to feed them adult flakes because these willbe too large for their tiny mouths. Also see the article .
