What Can Go With Guppies – The Ultimate Guide To Peaceful Community
You’ve likely seen a vibrant school of guppies darting through an aquarium and felt that immediate spark of joy. Their shimmering colors and playful personalities make them the undisputed kings of the beginner hobby.
However, once you have your guppies settled, the next logical question is how to expand your aquatic family safely. Knowing what can go with guppies is the difference between a peaceful underwater paradise and a stressful environment for your fish.
In this guide, I’m going to share my years of experience to help you choose the perfect companions. We will cover everything from compatible schooling fish to the best “cleanup crew” invertebrates for your tank.
Understanding the Guppy Temperament
Before we dive into specific species, we need to understand the disposition of the Fancy Guppy (Poecilia reticulata). Guppies are incredibly social, active, and generally peaceful creatures that occupy the top and middle layers of the water.
They are “livebearers,” meaning they give birth to free-swimming fry rather than laying eggs. This means they are constantly on the move, looking for food or interacting with their own kind.
Because they have long, flowing fins, they are often targets for fin-nipping species. Therefore, any tank mate you choose must be just as peaceful as they are.
Choosing What Can Go With Guppies: The Golden Rules
When you are researching what can go with guppies, you need to look at three main factors: water chemistry, temperature, and temperament. Guppies prefer harder water with a higher pH, usually between 7.0 and 8.5.
It is a common mistake to put them with soft-water species like Discus. While some fish can adapt, it is always better to match species that naturally thrive in the same environment.
Temperature is also vital; guppies like it warm, ideally between 74°F and 82°F. Any companion you select must be comfortable in this specific range to ensure long-term health.
The “Size Matters” Rule
In the fish world, if something fits in a mouth, it usually ends up there. Guppies are small, typically reaching only 2 inches in length.
Avoid any large predatory fish, even if they are labeled as “semi-aggressive.” A large Angelfish or a Cichlid might see your colorful guppies as an expensive snack rather than a friend.
Activity Levels and Space
Guppies are “busy” fish. They don’t sit still. If you pair them with very shy or slow-moving fish, the guppies’ high energy might stress out their neighbors.
Ensure your tank is large enough—at least 10 to 20 gallons—to allow every species to have its own territory and swimming lane.
Top Schooling Fish to Pair with Guppies
Schooling fish are fantastic because they add a sense of movement and “filling” to the middle of the tank. Here are my top picks that get along famously with guppies.
Neon Tetras and Cardinal Tetras
Neon Tetras are perhaps the most iconic community fish. Their bright blue and red stripes complement the varied colors of guppies perfectly.
They are peaceful and stay relatively small, making them ideal neighbors. Just be sure to keep them in a group of at least six to keep them feeling secure.
Harlequin Rasboras
Rasboras are incredibly hardy and have a unique “porkchop” shape on their sides. They are calm, stay in the middle of the water column, and won’t bother your guppies’ fins.
I find that Harlequin Rasboras add a nice textural contrast to the flowy tails of the guppies. They are a “set it and forget it” kind of tank mate.
Endler’s Livebearers
If you love the look of guppies, why not add their close cousins? Endlers are smaller, even more active, and can actually crossbreed with guppies.
They share the exact same water requirements and diet. Just be prepared for a population explosion if you have males and females of both species!
The Best Bottom-Dwellers for a Guppy Tank
Adding fish that live at the bottom of the tank is a great way to utilize all the space in your aquarium. These fish also help by cleaning up excess food that falls past the guppies.
Corydoras Catfish
Corys are the golden retrievers of the fish world. They are constantly snuffling through the sand, looking for leftovers, and they are completely harmless.
Whether you choose Bronze Corys, Panda Corys, or Albino Corys, they will live happily below your guppies. Always keep them on a soft sand substrate to protect their delicate barbels.
Kuhli Loaches
If you want something a bit more “exotic,” the Kuhli Loach is a strange, eel-like fish that is a joy to watch. They are nocturnal, so they will come out at night to scavenge.
They are incredibly peaceful and will hide in caves or under plants during the day. They pose zero threat to your guppies or their fry.
Bristlenose Plecos
Unlike the Common Pleco which grows to two feet long, the Bristlenose stays around 4-5 inches. They are excellent algae eaters and keep the glass clean.
They are armored and peaceful, making them one of the safest options when considering what can go with guppies in a 20-gallon tank or larger.
Invertebrates: Shrimp and Snails
Many aquarists today are moving toward “shrimp tanks.” The good news is that guppies can live with many invertebrates, provided you offer enough hiding spots like Java Moss.
Amano Shrimp
Amano shrimp are the powerhouse of algae control. They are larger than Cherry Shrimp, which means adult guppies are much less likely to bother them.
They are busy, interesting to watch, and very hardy. I always recommend Amanos for beginners because they are less sensitive to water fluctuations than other shrimp.
Mystery Snails and Nerite Snails
Snails are the ultimate peaceful tank mates. They don’t have a mean bone in their bodies (or shells!).
Mystery Snails come in beautiful colors like gold, blue, and ivory. Nerite Snails are famous for being the best spot-algae eaters in the hobby and won’t overpopulate your tank.
Cherry Shrimp (With Caution)
You can keep Red Cherry Shrimp with guppies, but you must be careful. Guppies are opportunistic feeders and will eat baby shrimp (shrimplets).
If you have a heavily planted tank with lots of moss, the colony can usually survive and thrive. Just don’t expect every single baby shrimp to make it to adulthood.
The “No-Go” List: What to Avoid
It is just as important to know what not to put in your tank. Some fish are simply a recipe for disaster when paired with guppies.
Tiger Barbs
Tiger Barbs are notorious fin-nippers. They will see a guppy’s long, flowing tail as a target and will relentlessly chase them until the guppy is stressed or injured.
Avoid almost all Barbs unless you have a very large tank and a huge school of Barbs to keep their aggression internal. Even then, it’s a risk I wouldn’t take.
Angelfish
While they look graceful, Angelfish are actually Cichlids. As they grow larger, they become more territorial and predatory.
A full-grown Angelfish can easily swallow a small male guppy. It is best to keep these two species in separate setups.
African Cichlids
Most African Cichlids require very specific water chemistry and are far too aggressive for the peaceful guppy. They will claim the entire tank as their territory and bully any smaller fish.
Creating the Ideal Environment for Success
Compatibility isn’t just about the species; it’s about the environment. If your tank is “bald” with no decorations, your fish will feel exposed and stressed.
The Importance of Live Plants
I cannot stress enough how much live plants improve the quality of life for guppies and their tank mates. Plants like Hornwort, Anubias, and Java Fern provide cover.
They also help process nitrates, keeping the water cleaner for longer. In a community tank, plants act as “sight breaks” so that fish aren’t constantly staring each other down.
Feeding Your Community
When you have a mix of top-dwellers (guppies), middle-dwellers (tetras), and bottom-dwellers (corydoras), you need a variety of food.
Use a high-quality floating flake for the guppies and sinking pellets or wafers for the bottom fish. This ensures everyone gets a full belly without fighting for crumbs.
FAQ: Common Questions About Guppy Tank Mates
Can guppies live with Bettas?
This is a “maybe,” but usually, I recommend against it. Bettas can be aggressive toward guppies because the guppies’ colorful tails resemble another male Betta.
If you do try it, you need a large, heavily planted tank and a very mellow Betta. However, for a beginner, it is safer to keep them apart.
Can guppies live with Goldfish?
No. Goldfish are cold-water fish, while guppies are tropical. Additionally, Goldfish grow very large and will eventually eat your guppies.
How many guppies can I keep in a 10-gallon tank?
In a 10-gallon tank, I recommend keeping about 5-6 guppies. If you add tank mates like shrimp or snails, you can maintain a very healthy balance.
Do guppies need to be in groups?
Yes, guppies are social. You should keep them in groups of at least three. A good rule of thumb is to have two females for every one male to prevent the males from harassing the females.
Final Thoughts on Building Your Community
Designing a community tank is one of the most rewarding parts of the aquarium hobby. When you carefully consider what can go with guppies, you create a vibrant, active, and healthy ecosystem.
Stick to peaceful schooling fish like Tetras, hardworking bottom-dwellers like Corydoras, and helpful invertebrates like Amano shrimp. Avoid the nippers and the predators, and you will have a thriving display to enjoy for years.
Don’t be afraid to start slow. Add one species at a time, monitor their behavior, and enjoy the process of watching your underwater world come to life!
