Male to Female Ration

Keeping guppies can be a wonderfully rewarding experience, but you should remember to keep the male-to-female guppy ratio in mind. Under normal circumstances, having two or three males and five to seven females per tank is ideal for reducing the stress and potential risks of overcrowding on the female fish. Generally, the more females you have in your aquarium, the healthier they will be since males tend to harass them as they pursue mating. 

Substrate and Decorations

When it comes to the substrate for your guppy breeding tank, gravel is usually the best option since it provides a nice natural environment for them. You’ll also want to make sure you provide plenty of hiding places and plants where female guppies can take refuge from male chasing. Java moss, hornwort or any dense, leafy plants can work great for this purpose and also provide a place for the fry to hide if you’re planning on breeding guppies.

Filtration & Maintenance 

To keep your aquarium clean and healthy, it’s important to equip it with an efficient filtration system that will help remove toxins from the water. When selecting a filtration system, make sure to pick one that’s suitable for the size of your tank and can efficiently handle large amounts of waste. Additionally, regular water changes should be done every two weeks or so in order to keep the water parameters stable. 

Aquarium size When Setting Up a Guppy Breeding Tank

When it comes to the size of your guppy breeding tank, it’s important to remember that larger tanks are usually better since they create a more stable environment and offer more room for guppies to swim. Tank sizes should range from 10-20 gallons (45-90 liters) depending on the number of fish you plan on keeping in the aquarium. 


Keeping plants when setting up a guppy breeding tank can be one of the most rewarding experiences for an aquarium enthusiast. Not only do they enhance the beauty and look of the tank, but they also serve as additional sources of hiding for the inhabitants. Floating plants that grow on the water surface such as hornwort or duckweed are especially beneficial, as they flood their surroundings with oxygen and provide cover for fry to hide from predators.

Some plants that are good for hiding fry include Anubias, Java Fern, and Dwarf Sagittaria. Additionally, the addition of a few live plants to your aquarium can help maintain water parameters and keep nitrate levels low.


The anubias aquarium plant is a beautiful asset to any fish tank! This vibrant, deep-green foliage complements almost any other fish tank decoration, and its hearty nature makes it easier to care for than other aquatic plants. It can also live without substrate and thrive just fine in whatever environment it’s kept in, so if you’re an amateur fish-keeper, this is the perfect plant for you! Not to mention that the anubias aquarium plant helps keep your fish tank clean by absorbing nitrates from the water—so you can give your home aquascape an added boost with no extra effort on your part.

Java Fern

The Java Fern is an excellent aquarium plant to add life to your tank! Its hardiness in various tank conditions make it very easy to look after, making it suitable for beginner aquarists. With its lush leaves and adaptable nature, this freshwater plant can survive in a wide range of temperatures and lighting levels. Furthermore, Java Ferns don’t require a substrate, instead anchoring themselves on rocks or wood for support. The intricate lace like foliage adds character to any aquascape, giving you plenty of options for your underwater garden. So, give your tank some extra love by inviting the beautiful Java Fern into your home!

Dwarf Sagittaria

Dwarf Sagittaria is a popular addition to an aquarium, and it’s no wonder why! This beautiful aquatic plant adds a burst of color and life to any tank. With its slender leaves, it’s perfect for adding texture and making the space look more lively. It’s also known as a hardy plant, thriving in minimal light areas as well as well-lit spaces alike. Plus, its fast growth rate means you’ll be seeing lots of new growth soon. Whether you’re a first-time aquarium owner or an experienced hobbyist looking for a great addition, Dwarf Sagittaria should be top on your list. Its elegance and resilience are sure to make waves in any tank!

Floating Plants

Keeping guppies at home is a wonderful way to create a calming and engaging aquarium environment, especially when setting up a guppy breeding tank. Having floating plants for your guppy babies to hide in is an excellent way to keep them safe and provide them with more protection. Not only do these plants provide shelter for the little guys, but they are aesthetically pleasing as well. Floating plants offer more coverage for the water’s surface, creating a natural atmosphere that helps reduce fish stress— perfect for a happy home tank! Plus, these kinds of plants don’t require any substrate, making them super easy to take care of! So if you’re looking to give your guppies some extra love and security, try adding some floating plants to your next aquarium setup.

Breeding Boxes

Breeding box for guppies is an ideal solution when you want to ensure safe and comfortable birthing experience for your pregnant guppy. This breeding box clearly segregates the expecting mother from its natural inhabitants, giving her a stress-free environment where she can focus on the arrival of her new babies without disturbance. When your guppy has reached a certain point in her pregnancy, all you have to do is place her into the breeding box, and one by one witness the emergence of beautiful little newborns! Enjoy this heartwarming experience with these wonderful fishes: simply put the mother guppy in the designated breeding box, then wait and observe as she joyfully introduces you to her tiny offspring.

The guppy fry can then leave the box, and are thus prevented from being eaten by the mother. You should of course be careful of the other inhabitants in the aquarium, so you may use this solution in a separate aquarium.

However, please note that you should only keep the guppy mother in the box for minimum possible time, as it can be quite stressful on her.

Tank Divider

As a guppy owner, you know the importance of keeping your fry away from adult fish at all costs. But, with a tank divider with holes, you no longer have to worry about the safety of your precious baby guppies! These reliable separators are made from mesh or plastic and come in a range of sizes, giving you plenty of options for separating your fish. As well as providinging protection for small young fry, these tank dividers with holes also allow oxygen and water flow between both sides of the tank – so you know your fish will all be healthy. This divider gives your fry their own space in the tank to keep them safe and protected until they reach maturity. Not only will this help keep your fry safe, but it will also make tank management much easier since all adult fish stay on one side and all fry stay on the other. And with tons of options available, you’re sure to find a stylish design that fits right in with your aquarium decorations. All in all, this is an easy and cost effective way to keep your guppy fry safe!

Feeding Guppy Babies

When it comes to feeding guppy babies, you should take into consideration their size and specific nutritional needs. The food you select for your fry must be suitable and small enough for them to consume and digest easily. Commercial fry pellets are the most widely used food type, but there are other options such as crushed flake foods or even live baby brine shrimp. When giving your fry food, it is important to make sure you’re not overfeeding them. If you see that they aren’t able to finish the food given within a reasonable time frame, then reduce the amount offered. 

You should also be aware of water conditions during feeding time as uneaten food can pollute the water and cause ammonia spikes. This can be a problem for fish of all sizes, but it is especially dangerous for fry as they don’t have the same immunity to water contaminants as larger fish do. Make sure you are observing your tank closely while feeding and remove any uneaten food promptly after the meal is finished.


By following these simple steps, you’ll be well on your way to having your own flourishing guppy breeding tank in no time! Just remember to maintain balance in your planted tanks and keep an eye on water quality and you’ll be rewarded with a happy, healthy flock of guppies that are sure to bring lots of color and life into your home. With a little bit of patience and planning, when setting up a guppy breeding tank, anyone can create an amazing mini habitat for their favorite fish friends!
