Rasbora are some of my favorite fish in the hobby, and they do great in a community tank setup – if you know what else to pair with them.
The best tank mates for rasbora are cory catfish, neon tetras, guppies, endler’s livebearers, and cherry barbs. For non-fish tank mates, they do great with mystery snails, ramshorn snails, red cherry shrimp, and crystal red shrimp.
Let’s go over a few more options you have for tank mates that work well with rasbora.
The Corydoras catfish, or Cory Catfish, is the perfect tank mate for your Rasboras! These little custodians keep your aquarium very clean by eating algae, leftover fish food, and other biological sediments.
Corys are very peaceful and are rarely the troublemakers of the group. They do best in communities of three to five other Corys but can be content with only two if other fish are present.
Native to Sri Lanka, these fiery little fish add a pop of vibrant color to your tank setup. Cherry Barbs are very hardy and can hold their own even in the hands of a beginner fish tank owner.
These fish can get nervous when approached, so be sure to add plenty of freshwater plants and structures to hide in. Cherry Barbs are an at-risk species in the wild, so adding them to your tank will actually help preserve the species! Make sure you take good care of them.
Here are some other tank mates they’ll work well with.
Rummy Nosed Tetra
The Rummy Nosed Tetra, also known as the FireHead Tetra, is very popular among freshwater fish fans because they are so easy to care for. These fish do best in schools of five to six of the same species or with several similar sized fish, such as the Rasbora. It is recommended that you do not keep them with aggressive fish or fish large enough to eat them as they are relatively defenseless. They’ll do well with the same types of fish as neon tetras.
These little divas are lavishly decked out with reds, blues, greens, yellows, and black hues to make them one of the more exotic-looking small freshwater fish. A classic addition to any fish tank, Fancy Guppies are very popular among fish breeding hobbyists because they are so easy to breed and the color varieties are so vast and varied. If you do not want a tank teeming with hundreds of tiny fries in a matter of months, make sure you buy only males or only female fish.
Neon Tetras, another classically loved freshwater aquarium fish, will pair wonderfully with your Rasbora due to their docile nature. These fish vary from 1-1.5 inches and are characterized by their bright neon red and blue stripes. Interestingly, the fish change color from night to day, becoming grey and black at night or when the lights are dimmed. This is to conserve energy and rest for a new day of being fabulous!
Beautifully colored from bright yellow to light orange, the Honey Gourami are hardy and low maintenance fish. In the lazy rivers of Bangladesh, these fish are naturally found hiding among freshwater plants, so make sure to add some to your tank! Honey Gouramis are very active fish but still play well in the community, making them ideal tank mates for the Rasbora.
Rosy Tetras live among the roots of freshwater trees in Brazil, and they love to socialize with other fish of similar size. These fish look similar to the beautiful blossoms of the bleeding heart tree, earning them the nickname of heart minnows. These fish require pristine clean water, so it is best to also pair them with a cleaner fish like a suckerfish, a snail, or at least a really effective filter.
Black Mollies are one of the larger tank mates suitable for Rasboras, getting up to 3 inches in length when they’re fully mature. Black and robust due to a severe case of melanism, Mollies are truly a genetic anomaly and are captivating to watch. Males can become aggressive with each other when housed together. It is best to have only one male and a group of females, but these fish do well as single additions as well.
Red Wag Platy
The Red Wag Platy, or Blood Moon Fish, is a cheery addition to any tropical freshwater aquarium as they are mellow and peaceful community members. they rarely start fights or cause stress. These fish bear live young and are easy to breed for beginners. The black and red variety of the Red Platy is often referred to as the Mickey Mouse Platy and is an easy pet for beginners who are looking to get into fish keeping.
Apistogramma are a subspecies of dwarf cichlid that originates in South Africa. Brightly colored and growing up to 3.5 inches, they make an eye-catching addition to your aquarium, but these fish are carnivores and will eat any fish small enough to fit in their mouth. Keep this in mind when selecting your fish community.
These fish are very intelligent and will explore their environment thoroughly. They will even interact with things on the other side of the aquarium glass. They love to hide out in small caves and are defensive of their small territory space.
Hailing from down under in Australia, these small, colorful fish prefer to live in large communities of similar-sized fish. Rainbowfish prefer lots of open water to swim and exercise in, so make to have the accommodation for these little fellows before purchasing them. These fish are very hardy and can easily survive a variety of temperatures and social environments, avoiding conflict and sticking together.
Black Skirt Tetra
Translucent and flowy Black Skirt Tetras are sure to make people stop and stare at your aquarium due to their fascinating nature. Tetras are naturally schooling fish and will always prefer to live with several members of the same species.
Black Tuxedo Guppy
Another variation of the guppy fish, Tuxedo Guppies are beautiful with unique markings and incredibly easy fish to care for, requiring only one gallon of water per additional fish. (After the initial requirement of ten gallons.)
Dalmatian Mollies are a stunning and unique variation of Molly that will add charm and sophistication to any fish community set up. These fish are known for their ability to adapt to varying levels of saltwater due to their origin of living in estuaries.
Endlers look like a Picasso painting of neon greens, blues, purples, pinks, and reds. This small and active fish will add a multicolored dart of interest to your tank. Be warned, adult Endlers pair well with Rasboras, but small fries in the tank will likely be eaten.
Ramshorn snails are a topic of debate in many a fishkeeping forum. On one hand, they add almost no bioload to your tank, clean up algae, old food, and dead fish.
On the other hand, the more food there is, the more ramshorn snails there will be. They will breed out of control if you let them.
That’s never been a problem in my tank, though, and they come in some nice designer colors, so I recommend them.
17: Chocolate Gourami
This Chocolate Gourami will have your tank looking like a snack with its rich brown body reminiscent of a decadent dessert. These Gouramis get along swimmingly with other fish of similar size and temperament. Chocolate Gouramis thrive best in less aerated water because of their origin in the brackish Indonesian marshlands.
18: Pentazona Barb
The Pentazona Barb, Five-Banded Barb, or Tiger Fish is an iconic aquarium fish that will surely light up your tank with its bright orange hue and black stripes. These freshwater fish originate from peat marshes in Malaysia and love to school in groups of five or more.
Pentazona Barbs are very active and need plenty of space to school and socialize. With this in mind, these fish also need adequate hiding places like driftwood, plants, and rocks.
19: Betta Fish
I saved the best for last because. This particular pairing needs to be addressed in more detail. Betta Fish are fierce, exotic, and beautiful fish, often called Siamese Fighting Fish for their tendency to attack other Betta fish.
Betta Fish are characterized by the males having long, flowy, often vibrantly alluring fins. Their fins act much in the same way that peacock feathers do, flaring up to attract a mate or posture to other males and threats.
Not all other species on this list pair well with the majestic betta because he is a vicious fighter when cornered or harassed. Bettas will get aggressive with other male bettas, or fish with flowing colorful fins that look similar. Bettas are slow swimmers, so pairing them with a quick darting fish works just fine as long as there is abundant space for them to interact.
Bettas will likely keep their distance from other fish and will live in harmony with Rasboras as long as the tank is not overcrowded.
Female betta fish on the other hand will work just fine with most fish, including Rasboras. They are still semi-aggressive but are much less prone to fights.
Rasbora Tank Mates
The Rasbora is a lovely schooling fish that gets along well with others of the same species as well as many other fish. Pairing your Rasbora shoal, as long as they have adequate food and space, with any of the above fish will make for a colorful and peaceful fish community.
