Guppy Fish and Platy Fish – Can You Keep Them in Same Aquarium?

I love community fish tanks, where multiple spices of fish are kept together. Most beginners, however, try to keep fish spices in the same aquarium, which are not compatible with each other.

So you want to keep guppies and platies together in the same aquarium. But are guppy fish and platy fish compatible? Can you keep them in the same tank?

Yes, you can keep guppy fish and platy fish in the same aquarium. Both fish spices are livebearers and require very similar water conditions and food. So keeping platies together with guppies is a really good choice.

In the following, I will give you few very good tips on how to provide the best habitation for your guppies and platies. Please read along, if you want to learn more.

Tank Size for Guppy Fish and Platy Fish

I recommend a minimum 10 gallons (40 liter) tank size for guppies. Platies will also do well in a 10 gallons fish tank; however a 20 gallons (80 liter) aquarium would be a better choice for them.

Platies are slightly bigger than guppies and require a bit more swimming space.

Both guppies and platies live in swarm, so you can’t just buy one guppy and one platy. The will not do well when are kept alone.

So if you plan keeping multiple guppies and platies together, you should definitely choose a larger aquarium. You should pick at least a 20 gallons fish tank. Though, if you can, get a bigger fish tank.

In a 20 gallons tank you can easily fit 10-15 fish. With a good filtration and regular water changes, probably your aquarium will be able to hold even 20 fish.

Best Filter for Guppy and Platy Fish Tank

Filtration is the key element of every healthy aquarium. But what filter to buy for a guppy-platy aquarium?

For guppy fish and platy fish, you don’t need to use an expensive canister filter. When choosing a filter, always go for a bigger one. It is much better to over-filter your tank, rather than under-filter it.

So, for instance: if you need a filter for a 20 gallons aquarium, choose a filter that is recommended for at least 40 gallons (80 liters) aquarium. Also, make sure that the filter can hold enough filter media. This way, you will ensure that your tank is well filtered.

I highly recommend the AquaClear hang on back filter (on Amazon) for guppies and platies. This HOB filter comes in 5 different sizes and has a lot of space for filter media. It is equipped with a 3 stage filtration: mechanical, chemical and biological. The flow rate is adjustable, so you can control the water current.

Best Aquarium Plants for Guppies and Platies

Live plants are a great addition to every aquarium. Besides providing a pleasing look, plants help in filtering the water. Live plants will extract the excess nutrients from the water column, which may be harmful for your fish. On top of that, plans will provide hiding spaces for guppy and platy fry.

Here are the best beginner friendly plants that I recommend keeping with platies and guppies:

Frogbit | Java Moss | Java Fern | Hornwort | Anubias

  • Frogbit: is super low maintenance floating plant that has huge roots, providing lots of hiding place for fry. It grows very fast and sucks up a lot of nitrates from the water. Frogbit requires good lights in order to grow.
  • Java Moss: is a great addition to any fish tank. Java moss is considered a floating plant, but does not float at the surface of the water. It is not a very fast growing plant, but is very effective in filtering the water. Java moss can support low light conditions very well. Java moss is great for guppy and platy babies to hide.
  • Java Fern: is a beautiful and very hardy plant. Does not require high light and does not grow very fast. Its leaves can reach a size of up to 12 inches (30 cm). This plant has roots that can be attached to rocks, drift wood or other decoration. It should not be planted in the gravel.
  • Hornwort: grows really fast and will provide good habitat for fry. Though this plant can be anchored in the substrate, it can also be left to float at the top of the water surface. It is an excellent plant for beginners.
  • Anubias: is a slow growing plant with large heart or arrow shaped leaves. It is a very hardy plant, can live and survive in low light conditions and does not require much maintenance. Its stem should not be planted in the substrate, because requires light in order to survive. It is one of the best plants for beginners.

Best Food for Guppy Fish and Platy Fish

In order to keep your guppy and platy fish healthy, you need to provide them with a variety of high quality food. You can prepare your own fish food at home, or you can use commercial food which is more convenient.

When you buy fish food, always look for reputed brands. Choose fish food that will provide a complete diet for both guppies and platies. Use foods that are rich in vitamins and minerals and has high protein content.

I use and recommend the New Life Spectrum Optimium Flakes (buy from Amazon), which is great for both guppy and platy fish. This food can be feed to fry as well, just need to crush up the flakes into powder with your fingers.

I wrote a complete guide on the best flake foods; check it out for more details.

Breeding Platies and Guppies in Same Aquarium

Platies and guppies can’t be crossbred. Though, if you have females and males of both spices, sooner or later they will have babies.

After reaching maturity, both guppies and platies give birth to fry around every 30 days. Platies will give birth to 20-40 babies, while guppies can drop even 60 fry at a time.

Unfortunately parents will not take care of their babies, and if they don’t have enough hiding spaces, will get eaten by adult fish.

If you want to save some fry, give them live plants or separate the pregnant female into a breeding box, just before giving birth. Don’t keep the female for too long in a breeding box, because the small space can be very stressful for them.

If you did a good job saving guppy and platy fry, you will end up with a lot of fish very quickly. Certainly you can’t keep all of them, especially if you have a small aquarium.

Though, when the fry grow a bit, you can give them to friends or sell them online. You can join Facebook groups where you can trade them for plants of other fish.

You can also bring juveniles to your local fish store. Most local fish shops will not pay you, but often they will give you store credits, which you can use to buy fish food and other aquarium equipment.

So, whether you breed your guppy and platy fish by purpose or by accident, it is always fun to raise the babies and watch them grow.

Water Parameters for Guppy Fish and Platy Fish

The good thing about keeping platies and guppies together is that both can thrive in same water parameters.

Get a good aquarium heater from Amazon, which has an in-built thermostat and set it to 72-74 °F (22-24 °C). This is the best temperature for both guppy and platy fish.

Do regular water changes in order to remove nitrates and other chemicals from the water. A 30% weekly water change will be enough to keep water parameters stable. Don’t forget to use treat tap water with water conditioner. I highly recommend Seachem Prime from Amazon. It is one of the best water conditioner, which will remove chlorine and heavy metals from the water instantly.

Maintain the filter regularly and clean the mechanical filtration. You can also rinse the biological filter media in aquarium water. Dirty filter can be a big source of nitrates and ammonia. So, please keep it clean.
