Breeding Guppies

Breeding guppies is a popular hobby among fish keepers and pet enthusiasts. Knowing the basics of breeding guppies can help you have successful results when attempting to breed them in your own tank.

Male and Female Guppies:

Male guppies are typically larger than female guppies, with longer fins and more vibrant colors. Females usually have shorter fins, duller colors, and a rounder body shape compared to males. It’s important to note that some male guppy varieties may not be as colorful or showy as others due to their genetics. Female guppies also tend to live longer than males because they don’t expend energy on courtship displays like chasing other females or displaying for potential mates like males do.

Preparing for Breeding:

Before attempting to breed your own guppy population, it’s important that you create an environment suitable for breeding by providing plenty of hiding places such as plants or rocks so the fry (baby fish) will have somewhere safe from predators once they hatch out of their eggs. Additionally, it’s recommended that you use a separate tank specifically dedicated for breeding purposes since this will make it easier to monitor water quality parameters such as pH levels which should be kept stable during the entire process in order for successful spawning (reproduction).

When mating season arrives, male guppies will start chasing after female ones in order to court them into submission before finally mating with them by releasing sperm onto her body near her gills where she then stores it until she is ready to lay eggs. At this point, she releases the stored sperm over her eggs allowing fertilization to take place externally rather than internally like most other species of fish do. Afterward, she lays her eggs either directly onto plants or objects within the aquarium where they remain until hatching several days later depending on temperature conditions present inside the tank at any given time.

Key Takeaway: Male guppies are larger and more colorful than females, who live longer due to not expending energy on courtship displays. When preparing for breeding, provide hiding places for fry, use a separate tank and monitor water quality parameters such as pH levels. During mating season males court the female before releasing sperm onto her body near her gills which she stores until ready to lay eggs externally.

Caring for Fry (Baby Guppies)

Feeding Fry:

Feeding fry can be a challenge, as they are so small and require very specific foods. The best food for baby guppies is newly hatched brine shrimp or microworms. These tiny organisms provide the nutrition that young guppies need to grow and thrive. You should feed your fry several times a day in small amounts, making sure not to overfeed them.

Separating Fry from Adults:

Keeping adult fish with their babies can lead to disaster if the adults decide to snack on them. It’s important to separate the fry from any other fish you have in your tank as soon as possible after they are born. A breeding net or breeder box attached inside of your aquarium is an easy way to do this without having to move any of your existing fish out of their home.

Once separated, it is important to provide adequate housing for the fry so they can develop properly and stay safe from predators such as larger fish or snails. A 10-gallon tank with plenty of hiding places like plants, driftwood, rocks etc., will give them enough space while still providing protection against bigger creatures in the tank. Additionally, make sure there is ample oxygenation and filtration available since these little guys produce a lot more waste than their adult counterparts.

Common Questions About Breeding Guppies

When it comes to breeding guppies, there are many questions that arise. How long does it take for them to mate? How many babies do they have? What should I do with the extra fry? Let’s look at each of these questions in more detail.

How Long Does It Take For Guppies To Mate?:

Generally speaking, mating can occur within a few days or weeks after introducing male and female guppies into the same tank. However, if you want your fish to produce healthy offspring, then you should wait until both sexes are mature before attempting to breed them. This usually takes about two months from when they were born.

How Many Babies Do Guppies Have?:

On average, a female guppy will give birth to around 20-30 fry (baby guppies) per litter; however this number can vary depending on the size and health of the mother as well as other environmental factors such as water temperature and quality.

If you find yourself with too many baby guppies in your tank then there are several options available. You could donate some of them to an aquarium store or local pet shop, set up another tank specifically for raising young fish, or even offer them up for sale online or through classified ads websites like Craigslist. Whatever option you choose, make sure that all new homes provide adequate care and nutrition for their new inhabitants.


In conclusion, breeding guppies is a rewarding and fun experience. It can be challenging at times, but with the right knowledge and preparation it can be a great success.
