Can Guppies And Mollies Breed?

Yes! It’s entirely possible to breed guppies and mollies together. In fact, if you keep guppies and mollies together in the right conditions, there’s a good chance they’ll breed on their own without your input.

The reason guppies and mollies are able to breed together is because they’re so closely related, and they’re actually both from the same family (Poeciliidae).

What Do Guppy/Molly Hybrids Look Like?

Guppy/molly hybrids can vary massively in how they look due to the breeding process. Generally, though, they’re going to be as large as mollies in size but a bit more decorative, like guppies.

How Do You Breed Guppies With Mollies?

If you’re interested in your own guppy/molly hybrid, then here are the steps you can take to breed them successfully!

Make Sure The Water Temperature Is Correct

First of all, you should make sure that the water temperature is perfect for breeding. The ideal temperature is 78F, as this fits nicely in the temperature both guppies and mollies breed in. However, you can go as high as 82F with a good level of success and as low as 74F.

Make Sure The pH Is Correct

As well as making sure the temperature is correct, you should also make sure that the pH in the tank is perfect for them too! For ideal breeding conditions, you should keep the tank’s water slightly alkaline at 7.5 – 8.0 on the pH scale.

Feed Them Well

While you’re trying to get your fish to breed, you should also make sure you’re feeding them well so they’re less stressed and have enough energy to carry their babies to term. Remember, fish are less likely to breed if they feel like they’re living in scarcity, so good feeding is essential.

Both fish are omnivores, so you should be adding a mix of high-quality proteins and plant matter into your tank.

Choose Suitable Fish

When you’re going to breed these two fish, their offspring are often going to be less healthy. Because of this, you need to make sure you’re breeding high-quality fish. So, try purchasing some from a professional breeder. 

And when you’re looking for fish, look for the ones that are brightly colored, lively, and active. These are all signs that the fish are healthy! 

Separate Female Mollies Once They’re Pregnant

Once you know that your mollies have become pregnant, it’s time to separate them from the tank. This way, you can make sure they’re in an environment that is going to be less stressful for them, and secondly, it will be much easier to keep an eye on them and their pregnancy throughout the process this way!

Remove The Guppy/Molly Hybrids After Birth

When your mollies have given birth, the last step is to remove them from the tank. If you don’t, then the chances are they may end up eating their fry.

What To Remember When Breeding Mollies And Guppies

If you’re going to breed mollies and guppies together, then there are a few things you’ll need to remember for the health and well-being of your fish.

Use A Large Tank

It’s always a good idea to breed mollies and guppies together in a large tank and give them plenty of places to hide. For fish to breed, they need to feel relaxed and safe. By giving them a large tank with plenty of hiding spaces, you’re providing this to them.

Maintain A Good Molly To Guppy Ratio

You should also make sure you’re keeping the ratio right between the males and females. For every male guppy that you put into the tank, there should be between 2-4 mollies. This way, it’s much less likely that aggression will occur, and breeding is much more likely to happen as well.

Only Breed Female Mollies And Male Guppies 

The most important thing you can do is make sure you’re only breeding female mollies and male guppies. Guppies are so much smaller than mollies, so if you breed them the other way around, then it can cause serious harm to your female guppies and can even end up killing them.

Make Sure You’re Removing The Parents From The Tank ASAP

It can’t be stressed enough. You should also make sure you’re removing the parents from the tank as soon as the fry are born to ensure they don’t end up being eaten. Otherwise, you’ll have to breed your fish all over again.

The Fry Won’t Be As Strong

Whenever you’re crossbreeding, the fry will never be as strong as when you’re breeding the same species. Because of this, you should accept that they may not live as long, or if they are born, they may not be as healthy.

The Offspring Will Be Infertile

Also, when you create molly/guppy hybrids, the offsprings are always going to be infertile, so you won’t be able to breed them with each other again.
