Best Fish To Put With A Betta – Your Guide To A Peaceful Community
Is your stunning betta floating solo in his tank, a lonely king in a glass castle? We’ve all seen it. While these fish are beautiful on their own, many aquarists dream of creating a vibrant, active community tank with their betta as the centerpiece.
You might have heard that bettas are too aggressive for tank mates. While they certainly have a feisty reputation, the truth is a bit more complex. With the right knowledge and setup, your betta can not only tolerate but thrive among friends.
Imagine a beautifully planted aquarium where peaceful schooling fish dart below, diligent snails clean the glass, and your betta swims confidently, his colors shining brighter than ever. This isn’t just a dream; it’s completely achievable.
This comprehensive best fish to put with a betta guide will walk you through everything you need to know. We’ll cover how to choose the right companions, set up your tank for success, and create the peaceful aquatic haven you and your betta deserve.
Understanding Your Betta’s Personality: The First Step to Success
Before you even think about adding new fish, the most important step is to understand your specific betta. Think of it like this: not all people are social butterflies, and not all bettas are aggressive killers. Their personalities vary wildly!
Some bettas are incredibly mellow and won’t bother a soul. Others, especially those bred for fighting, might see any tank mate as a threat. Spend time observing your fish. Is he highly active and territorial, constantly flaring at his own reflection? Or is he generally calm and curious?
A great pro-tip is the “mirror test.” Hold a small mirror to the glass for a few seconds. If he flares intensely and tries to attack it relentlessly, he might be on the more aggressive side. If he flares for a moment and then loses interest, he’s likely more docile. This isn’t a perfect science, but it gives you a valuable clue.
The Golden Rules: Essential Best Practices for Betta Tank Mates
Success isn’t just about picking the right fish; it’s about creating the right environment. Following these best fish to put with a betta best practices is non-negotiable for a peaceful tank. Getting this part right is the key to understanding how to best fish to put with a betta without causing stress.
H3: Tank Size is Everything
Forget the tiny cups and bowls. For a betta–only tank, 5 gallons is the bare minimum. If you want to add tank mates, you need to upgrade. We recommend a minimum of 10 gallons, but a 20-gallon long tank is even better.
More space means more territory for everyone. It reduces stress, dilutes waste, and gives other fish plenty of room to escape if your betta gets grumpy. A cramped tank is a recipe for conflict.
H3: Create a Densely Planted Paradise
This is one of the most critical best fish to put with a betta tips we can offer. A bare tank creates a direct line of sight, which can encourage aggression. A tank filled with live plants, driftwood, and caves breaks up that line of sight.
Plants and decor provide hiding spots for tank mates, making them feel secure. They also give your betta interesting places to explore, reducing boredom-driven aggression. Don’t worry—these fish are perfect for beginners! Try easy plants like Java Fern, Anubias, or Hornwort.
H3: Quarantine All New Arrivals
Never, ever add new fish directly from the store bag into your main tank. New fish can carry diseases like Ich that could wipe out your entire aquarium. Set up a separate, small quarantine tank (even a 5-gallon will do) and observe new arrivals for 2-4 weeks before introducing them.
This step is what separates novice fishkeepers from experienced ones. It protects your beloved betta and prevents a heartbreaking disaster.
H3: The Proper Introduction Method
Don’t just plop the new fish in! This can trigger your betta’s territorial instincts. The best method is to add the new tank mates before the betta. If the betta is already in the tank, remove him temporarily to a cup or breeder box.
Rearrange the decorations and plants a bit, then add your new fish and let them get settled for an hour. Finally, re-introduce your betta. This little trick resets his sense of territory, making him feel like the “new guy” and less likely to be aggressive.
Top 10 Best Fish to Put With a Betta: Our Aquifarm Favorites
Ready for the fun part? Here is our list of tried-and-true companions for your betta. This is more than just a list; it’s a curated best fish to put with a betta care guide to help you make the perfect choice.
- Ember Tetras: These tiny, flame-colored fish are fantastic. They are peaceful, fast enough to avoid a curious betta, and their muted color won’t trigger aggression. Keep them in a school of 6+ in a 10-gallon tank or larger.
- Harlequin Rasboras: A classic betta companion for a reason. They occupy the middle of the water column and are known for their calm demeanor. A school of 6-8 is perfect for a 20-gallon tank.
- Pygmy Corydoras: These adorable, miniature catfish are bottom-dwellers, meaning they’ll stay out of your betta’s way. They sift through the substrate for food and are incredibly peaceful. Keep a group of at least 6.
- Kuhli Loaches: These quirky, eel-like loaches are masters of hiding. They are nocturnal and spend most of their time burrowing in sand or hiding under decor. Your betta will rarely even know they’re there. A 20-gallon tank is best.
- Neon Tetras (with caution): While popular, Neons can be hit or miss. They are generally peaceful, but their bright blue stripe can sometimes attract a betta’s attention. If you try them, ensure you have a large school (8+) in a heavily planted 20-gallon tank to diffuse any potential aggression.
- Nerite Snails: The perfect cleanup crew. They are voracious algae eaters, and their hard shells make them completely betta-proof. They also cannot reproduce in freshwater, so you won’t have a population explosion.
- Amano Shrimp: If you want to try shrimp, Amanos are your best bet. They are larger and more robust than other dwarf shrimp, making them less likely to be seen as a snack. Provide tons of moss and hiding spots.
- Celestial Pearl Danios (Galaxy Rasboras): These are stunning little fish, but they are also shy and fast. They are a great choice for a well-planted 20-gallon tank where they have plenty of room to feel secure.
- Otocinclus Catfish: “Otos” are small, peaceful algae-eating catfish. They are best added to a mature, stable tank with plenty of biofilm and algae to graze on. Keep them in a group of 5 or more.
- Female Bettas (in a sorority): This is an advanced option and should only be attempted by experienced aquarists in a 40-gallon or larger, heavily planted tank. A group of 5+ female bettas can sometimes live with a single male, but it requires careful monitoring and is not for beginners.
Fish to AVOID: A Recipe for Disaster
Just as important as knowing what fish to add is knowing what to avoid. Adding the wrong fish can lead to stress, injury, or death for both the betta and its tank mates.
- Fin-Nippers: Fish like Tiger Barbs or Serpae Tetras are notorious for nipping at long, flowing fins. Your betta’s beautiful fins will be an irresistible target.
- Brightly Colored, Long-Finned Fish: Male guppies are a prime example. A betta may mistake them for a rival male betta and attack them on sight.
- Other Labyrinth Fish: This includes Gouramis. They share the same family as bettas (and the ability to breathe air from the surface) and are often territorial, leading to intense fighting.
- Large or Aggressive Fish: Cichlids (like Angelfish), large barbs, and most other aggressive species will bully or even kill a betta.
- Goldfish: This is a common but terrible pairing. Goldfish are cold-water fish with a massive bioload (they produce a lot of waste), while bettas are tropical fish that need clean, warm water. Their needs are completely incompatible.
Common Problems with Betta Tank Mates (And How to Solve Them)
Even with perfect planning, you might encounter issues. Don’t panic! Here are some common problems with best fish to put with a betta and how to troubleshoot them.
My Betta is Chasing the New Fish!
A little chasing at first is normal as the pecking order is established. However, if it’s relentless, it’s a sign of high stress. Ensure the tank is heavily planted. You can also try a “time out” by placing the betta in a breeder box inside the tank for a day to let him see the other fish without being able to attack them.
The New Fish are Hiding Constantly.
This is a sign of fear. First, double-check that you have a large enough school for schooling fish (like tetras or rasboras); a small group will feel insecure. Second, add more cover! Floating plants, dense background plants, and caves will give them the confidence to come out and explore.
My Betta’s Fins Look Tattered.
This is a classic sign of fin-nipping. Observe your tank carefully to identify the culprit. Unfortunately, the only real solution here is to separate the offending fish from the betta. This is why choosing peaceful species from the start is so important.
A Sustainable Approach: Eco-Friendly Betta Keeping
Being a great aquarist also means being a responsible one. A sustainable best fish to put with a betta setup is better for the environment and often leads to healthier fish. Here are a few eco-friendly best fish to put with a betta tips:
- Choose Captive-Bred Fish: Whenever possible, purchase fish that were bred in captivity rather than wild-caught. This reduces pressure on wild ecosystems. Most of the fish on our recommended list are readily available as captive-bred.
- Go with Live Plants: Live plants are far superior to plastic ones. They act as natural filters, oxygenate the water, and provide a renewable source of cover for your fish.
- Support Responsible Retailers: Buy your fish from local fish stores or reputable online sellers who prioritize the health and ethical treatment of their animals.
Frequently Asked Questions About Betta Tank Mates
How many fish can I put with my betta in a 10-gallon tank?
In a 10-gallon, you are quite limited. A great combination would be your betta and a school of 6 small fish like Ember Tetras, OR your betta and a few Nerite Snails and Amano Shrimp. Avoid overstocking, as it can lead to poor water quality and stress.
Can I put a female betta with a male betta?
No, not permanently. They should only be brought together briefly for breeding purposes by experienced breeders. A male will likely harass and kill a female if housed in the same tank long-term.
Will my betta eat shrimp?
It’s a definite possibility. Bettas are carnivores, and small shrimp can look like a tasty meal. Larger shrimp like Amanos have a better chance of survival, especially in a tank with tons of moss and hiding places. It really depends on your betta’s individual personality.
Do bettas get lonely? What are the benefits of best fish to put with a betta?
While “lonely” might be giving them too much human emotion, bettas can definitely suffer from a lack of stimulation in a bare tank. The benefits of best fish to put with a betta are twofold: it provides enrichment for your betta by giving him things to watch and interact with (passively), and it creates a more dynamic, beautiful, and naturalistic ecosystem for you to enjoy.
Your Thriving Community Tank Awaits
Creating a community tank with a betta is one of the most rewarding projects in the fishkeeping hobby. It takes a bit more planning than a solo setup, but the result is a breathtaking display of color and life.
Remember the key takeaways from this guide: know your betta’s personality, provide a large and heavily decorated tank, and choose peaceful, appropriate companions. Be patient, observe your fish closely, and don’t be afraid to make adjustments.
You now have the knowledge and the tools. Go create that beautiful, bustling aquarium you’ve been dreaming of. Happy fishkeeping!
