Most fish can get along well with guppies and make a nice community aquarium.

If you are looking for a fish that can live peacefully with guppies, consider mollies, platies, swordtails, Endlers, and white clouds. All of these fish get along well with guppies and will occupy different areas of the aquarium so there is little competition between them. Other good tank mates are corydoras, tetras, and some types of catfish.

What Fish Can Live With Guppies

When it comes to aggressive fish, most of the guppies can’t tolerate them. You should keep guppies and other small schooling community fish in groups of at least six, but preferably more. The larger the school, the less likely they will be targets for predation by other large fish, in fact, you should consider a school of 12-20.

Swordtails are not only livebearers, but they also breed efficiently and get along well with other similar-sized fish like guppies or platys.

The sword-like fins at the bottom of this fish make it stand out. The coloration also helps, with its vibrant shades, unlike any other aquarium dweller you’ll see.

Swordtails are fascinating fish that come in an array of colors and styles. They like living together, but not too much! These omnivores can be found feeding on flake food or other small prey such as mosquito larvae (or even brine shrimp!).

  • Tank capacity: 20 gallons
  • compatibility: ten out of ten
  • Easy to look after.


Even though Mollies are very similar in size and temperament to guppies, they make excellent tankmates for much other freshwater fish.

The Molly fish is a hardy and lively species that can thrive in both fresh and saltwater aquariums.

Although not difficult, ensuring females are paired with males can be tricky. If you want your molly breeding success rate higher than 50%, then it’s crucial that the two don’t get separated, or else all hope may seem lost.

Give your guppies a friend with these gentle and peaceful fish who can get along not just in tanks but also across different types of water.

  • compatibility: 10/10

Another livebearing species, platies make excellent companions for guppies. But be prepared to breed or keep an eye out because these fish are known producers of babies intensively.

The platy is a beautiful little gem that doesn’t require too much care. It has the ability to change colors and patterns, so even if you don’t have perfect water conditions for them they will still shine.

The platy is a popular fish for new aquarium owners. They are gentle, easy to care for and good beginner pets that can also keep up with more experienced tank-mates when it comes time to move on from their quarantine tanks.

Cory Catfish

Unlike many other types of fish, Cory Catfish are peaceful and easy to keep. They can be found in a variety of colors but regardless will get along with most others if given the chance.

Freshwater aquarium fish are great for new aquarists. They love to scavenge in the substrate of your tank, but because their fins are delicate I recommend setting up a sand rather than gravel bottom.

Guppies and Cory Catfish get along great, but you can definitely house more than one type of freshwater fish in your tank. It will be a happy home for all.

  • Tank capacity; 20 gallons
  • compatibility: 10/10
  • level of maintenance: simple.

Harlequin Rasboras

Harlequin rasboras are a fun, easy-going fish that can be great for beginners. They have an accentuated copper-red color with one green triangle on their rear end.

If you want your betta fish to have a bright and colorful personality, then it’s best that they live in groups. The more color-coordinated friends around him or she will make for an exciting life full of thirty presentations.

Harlequin rasbora needs a tank between 20 and 30 gallons to live comfortably. They get along well with other peaceful fish that are also mid-level dwellers, like guppies or Molly but should not be mixed in large tanks where there’s potential for territorial behavior and competitive tension! 

These two species don’t often compete if their dietary needs arc met–hedgehogs can easily feed on both frozen foods such as cubes & flakes while others prefer fresh meaty cuisine.

Cardinal Tetra

The colorful and active Cardinal tetra is an excellent choice for beginners. As a schooling species, it’s important to keep them in groups of 7 or more so that they don’t feel lonely when all alone at home.

It’s hard enough keeping one fish alive, but try to keep three? That’s what the Cardinal tetra requires for breeding. They’re notoriously tricky and you’ll need an entire tank just devoted solely to them.

Nerite Snails

The nerite snail is a common freshwater gastropod that has been noted for its ability to consume large quantities of algae without harming the fish it’s paired with. 

This makes them an excellent choice if you want your tank free from unwanted plant life while still having something useful to do all day long.


Most fish can get along well with guppies and make a nice community aquarium. However, some exceptions may cause problems. Male guppies have been known to harass smaller fish, such as neon tetras. 

The presence of females will usually calm the males down and they become more docile; however, discretion is advised when keeping males and females together as the guppies may mate excessively, which can lead to overpopulation. 

Avoid keeping fish that are known to be aggressive or nippy, as they may harass or even kill the guppies. These include tiger barbs, piranhas, and certain species of cichlids. It is also best to avoid Keeping fish that require different water conditions than guppies.
