How Do You Keep Baby Guppies Alive?

Guppies are livebearers that reproduce very easily. When guppy fry are born, they are already developed and start moving on their own. Adult guppies don’t take care of baby guppies, and they are left by their parents. In fact, adult guppies including their parents feed on guppy fry. Therefore, it is important to take some precautionary steps to keep your baby guppies alive and safe.

To keep your baby guppies alive, you must ensure that the water parameters including temperature are suitable. Feed them properly with variety and healthy food as often as required in an easy to consume size. Likewise, you should separate baby guppies from adults [including the mother] or else they will feed on them.

However, you can fill the tank with natural or artificial plants if you don’t want to separate the guppy fry. These plants will prevent the adults from eating all the baby guppies because it will provide hiding and resting place for them. Nevertheless, this method does not guarantee the safety of all the guppy fry, but some can still escape.

How Are Baby Guppies Born?

Guppies are livebearers, hence they don’t lay eggs. They give birth to their young ones alive without external fertilization.  Guppies usually give birth once every 30 days until they are about 2-2.5 years old when they can no longer give birth. Female guppies are capable of giving birth to about 20-60 fry at a time.

The pregnant female guppy usually hides when it is time to give birth.  The female guppy can be in labour for a few hours, and in some cases, they can spend up to a day or two. At birth, the guppy fry are deformed and inactive. It however takes a couple of hours before they straighten up and start swimming freely.

Once the guppy starts swimming, they will constantly look for hiding places to rest at intervals. They are also seen to be in constant search for food to keep up with their rapid metabolism and growth. It is important to separate guppy fry from mother and other adults to prevent them from being preyed on.

How Do You Save Your Guppy Fry From Adult Guppy If You Don’t Have A Separate Tank

The generally recommended method of keeping your fry from being fed on by adults is by keeping them in a separate tank. You can also seek alternatives if you don’t have a separate tank or you can’t afford one.

You can make use of a bigger glass jar or plastic container to separate the pregnant female from other adult guppies till the fry are born. Alternatively, you can get a breeding box. You can insert this breeding box in the tank and you don’t have to worry about separate water maintenance. You should however extract the female guppy after giving birth and only the fry will remain.

Also, you can protect your fry by providing them with hiding place in the tank. Live or artificial plants are often very suitable for this hiding place. The plants will provide cover for them for about 2 weeks until they are bigger and stronger.


Breeding guppies and raising fry is easy, but it is quite important to protect your baby guppies from adult guppies till they are big and strong enough.  Good food, good water parameters, and protection from adult guppies are sufficient for you to raise a healthy and colourful guppy from fry to adult.
