Top 10 Compatible Guppy Tank Mates That Will Brighten Up Your Aquarium

Guppies are one of the most popular freshwater fish in the hobby, with their small sizes, good reputations for compatibility, and of course, incredible patterns and colors.

They have fantastic personalities too and can be found in the majority of fish stores across the globe, making the guppy fish readily available.

Sometimes the guppies can be somewhat overlooked by the more advanced aquarists, perhaps due to their beginner compatibility, and relatively low maintenance behavior, especially for tropical fish. However, these rainbow fish are absolutely mesmerizing, with an abundance of incredible multicolors, and patterns that will keep your eyes fixated on them all day long.

Guppy tank mates

Typically, as is true with many other extremely colorful fish, they tend to be pretty aggressive by nature, but not the guppies, they embody an incredibly calm and peaceful nature and will make a fantastic addition to any aquarium tank with peaceful fish residing in it.

The only time you will likely come across aggressive guppies is if the tank only consists of the male guppy. If you have a mixture of both male and female guppies then you will be fine.

Guppies have a somewhat unique reproduction as they are livebearers, which means that they do not lay eggs when they reproduce, instead, their eggs grow inside of them and when they eventually do give birth, they do so to live and freely swimming fish.

Due to this, many hobbyists will find themselves getting large guppy breeding communities, which is not only good for experience and personal gain, but it can be financially rewarding too, should you decide to sell the guppies.

Here are the Best Tank Mates for Guppies

Cardinal Tetras (Paracheirodon Axelrodi)

The Cardinal Tetra, much like the Guppies, is a favorite amongst hobbyists and has been for a number of years. Their two primary colors consist of a neon blue and a deep red, in straight lines running across their bodies. They are small fish, much like the Guppy fish species, however, they are slightly bigger and tend to grow to a maximum of 2 inches long.

Their incredible coloration is on full display when they are in darker water, and they will look amazing in any group of fish, or fish community. Many hobbyists overlook these beauties, perhaps due to their high price and similarities to the Guppies. But they are completely different fish and are compatible with pretty much all peaceful fish.

Female Betta Fish (Betta Splendens)

It is so important to understand that this suggestion is for female betta fish, not male betta fish! Females are a lot less aggressive than their male counterparts and are compatible with most peaceful fish communities.

The only downside to female betta fish is that they tend to not be as vastly colored or as beautiful as the males, but they are still incredibly stunning nonetheless. Do not let that discourage you from the female bettas, you will likely still find fantastic female betta fish that are colorful and pretty.

Again, similarly to the Guppies, these Bettas will typically grow to around 3 inches (7.6 cm) in length, which is an ideal size for the community you will create around your Guppies.

Rummy Nose Tetra (Hemmigramus Blehri)

Despite the rather amusing name, these tetra fish are always a fantastic addition to most aquariums. Their coloration and pattern are a sight to behold too, with an almost completely transparent body, deep-red face, and almost a zebra-patterned tail! They enjoy a planted environment, so having a rather heavily planted tank will reduce stress and bring much happiness to this fish - and you as the owner!

Rummy Nose Tetra

The Rummy Nose Tetra tends to grow to around 2 inches (5 cm) in length, which is a perfect size for a Guppy tank mate, and they are very much a community fish - peaceful by nature, and incredibly well-behaved. It is certainly advised to keep these in groups of 5 or more to keep them happy and stress-free.

White Cloud Mountain Minnow (Tanichthys Albonubes)

Despite having one of the most outrageous names in the entire aquarium and fishkeeping game, they have one of the most peaceful and loveable personalities too!

They come in a wide variety of different and stunning colors and are schooling fish, so they love being in big groups. Purchasing a school with many different colors will look incredible in any aquarium. Again, like the majority of fish that enter this list, they are small in size, much like the Guppies, growing to around 2 inches (5 cm) in length.

Neon Tetra (Paracheirodon Innesi)

The Neon Tetra is without a doubt one of the most popular fish to grace the hobbyist game, and for good reason too! They are so unique and beautiful, with their "neon" coloration, playful nature, and peaceful behavior. They make for the perfect fish, whether you are a beginner or an expert hobbyist.

Neon Tetra

Neon Tetras will typically grow to around 1.5 inches (3.8 cm) in length and are pretty easy to care for. They enjoy being in large groups of 6 or more, and will thrive in a diverse tank with plenty of room and other fish of a peaceful nature.

Harlequin Rasbora (Trigonostigma Hetemorpha)

Another absolute fan favorite is the Harlequin Rasbora. These fish suit almost any kind of aquarium environment and they make for awesome Guppy tank mates. Not only are they fantastic for beginners and experts alike, but they are perfect community fish and model citizens.

These Rasboras come in many different and bright colors too, and if you find the right colors to complement your Guppies, then you will have yourself a very bright and beautiful tank. They are typically small fish, growing to a maximum of 2.5 inches (6.4 cm) in length usually.

The only downside to these fish is that they are pretty rare to find in pet stores, and you will most likely need to go to an actual fish store to locate them, and even then you could potentially find yourself out of luck.

Dwarf Suckers (Otocinclus)

The dwarf suckers are a member of the catfish family, in fact, they are one of the smallest members, only growing to a maximum of 2 inches (5 cm) long. Not only are these Dwarf Suckers a cool addition to any fish community due to their uniqueness, but they serve a pretty useful purpose too.

Dwarf Sucker

They are well-known for being brilliant algae eaters and they are respectful towards your aquarium ornaments and plants, as well as other fish. They need to be kept in small groups and are extremely compatible with guppies.

Kuhli Loach (Pangio Kuhlii)

Perhaps the strangest fish to enter the list is the Kuhli Loach. These fish take up the appearance of a snake-like eel, however, they are indeed in the loach family of fish. They are certainly one of the largest on the list too, reaching up to 4.5 inches (11.5 cm) in length. They are also sometimes referred to as a Coolie Loach or Leopard Loach.  

The Kuhli Loaches are known for being fantastic tank mates of the guppy, this is due to multiple reasons. Their coloration is somewhat plain, with these fish often taking up a pale orange and dark brown color, and despite looking rather menacing, they have a very peaceful and playful personality and will be entertaining for you and your guppies.

Swordtail Fish (Xiphophorus Hellerii)

Swordtail fish is a truly incredible addition to the list, and certainly a fitting final entry. They are typically brilliant community fish as they are peaceful and fun, enjoying the company of their own, and other fish that happen to be in their community.

Swordtail Fish

They are seriously awesome aesthetically too, usually sporting bright orange bodies with, you guessed it, a sword-shaped tail! They are the biggest fish on the list, growing to a maximum length of 5.5 inches (14 cm) with their tails often outsizing their bodies, so some careful consideration is certainly needed before purchasing them, and they should be kept in small mixed-sex groups.

Keeping them with smaller fish such as the guppies is a match made in heaven as they are super compatible, and their unusual patterns, colorations, and body shapes really do compliment one another.

Conclusion

In conclusion, guppies are an awesome fish for any hobbyist level, and finding the perfect compatible tank mate has never been easier. Due to their awesome color, you want fish that accompany them to be flattering, and all of the inclusions on this list do just that.

It is, however, always pivotal that you conduct additional research into the specific fish you want to purchase for your aquarium, and additionally, you need to follow the correct steps and procedures in order for your new fish to settle in the best they can without bringing in any unwanted diseases, or worse!
