Can Betta Fish Live with Other Fish?
Yes, betta fish can live with other species—but only under the right conditions. Bettas are known for their aggression, especially males, but many aquarists successfully keep them in community tanks with peaceful, non-threatening companions.
The key is selecting the right tank mates, providing plenty of space, and minimizing stressors. Bettas need calm neighbors that won’t nip fins or compete for territory.
Top 12 Best Betta Fish Tank Mates
Here’s a breakdown of the most compatible species to house with your betta fish, based on years of aquarium experience and behavior studies.
1. Corydoras Catfish
- Temperament: Peaceful bottom dwellers
- Tank Size: 20 gallons or more
- Why They’re Compatible: They stay near the substrate and avoid your betta’s territory.
Cory cats are social and should be kept in groups of at least 4-6. They help clean up leftover food and won’t bother your betta.
2. Kuhli Loaches
- Temperament: Shy and peaceful
- Tank Size: 20 gallons minimum
- Why They’re Compatible: They’re nocturnal and spend time hiding or burrowing.
Kuhli loaches rarely cross paths with bettas and help control food waste. Be sure to use soft substrate to protect their delicate bodies.
3. Harlequin Rasboras
- Temperament: Peaceful schooling fish
- Tank Size: 15 gallons+
- Why They’re Compatible: They’re fast, peaceful, and not flashy enough to trigger betta aggression.
Keep them in groups of 6 or more. Their orange and black coloration adds vibrancy without threatening your betta.
4. Ember Tetras
- Temperament: Non-aggressive
- Tank Size: 10 gallons+
- Why They’re Compatible: Small, peaceful fish that won’t compete for dominance.
Embers are bright but not showy, making them ideal for a calm betta community tank. Provide lots of hiding spots.
5. Otocinclus Catfish
- Temperament: Shy, peaceful algae eaters
- Tank Size: 15 gallons minimum
- Why They’re Compatible: They’re tiny, quiet, and help clean algae.
Otocinclus do best in small groups. They require clean, well-oxygenated water, so regular maintenance is key.
6. Mystery Snails
- Temperament: Non-threatening
- Tank Size: Any size (10+ recommended)
- Why They’re Compatible: They clean up algae and don’t interact with bettas.
Bettas usually ignore mystery snails, but monitor closely. Avoid overfeeding to prevent snail overpopulation.
7. African Dwarf Frogs
- Temperament: Passive and fun to watch
- Tank Size: 10 gallons minimum
- Why They’re Compatible: They inhabit different zones of the tank and aren’t aggressive.
Feed frogs with tongs to ensure they get enough food. Keep water shallow and well-filtered.
8. Neon Tetras
- Temperament: Peaceful and active
- Tank Size: 15-20 gallons minimum
- Why They’re Compatible: Their small size and fast movement help them avoid trouble.
Neons are schooling fish—keep at least 6 to reduce stress. Avoid if your betta is overly territorial or long-finned.
9. Chili Rasboras
- Temperament: Very peaceful
- Tank Size: 10 gallons+
- Why They’re Compatible: Too tiny and shy to bother or trigger your betta.
These micro fish thrive in soft, acidic water—similar to bettas. Keep them in groups of 8+ for best health and confidence.
10. Ghost Shrimp
- Temperament: Peaceful scavengers
- Tank Size: 10 gallons+
- Why They’re Compatible: They clean up waste and food scraps without disturbing bettas.
Be careful—some bettas may view shrimp as snacks. Introduce them in tanks with lots of cover.
11. Endler’s Livebearers
- Temperament: Active and peaceful
- Tank Size: 10 gallons+
- Why They’re Compatible: Less aggressive and showy than guppies
Choose drab-colored males if your betta tends to flare. Avoid females unless you want lots of fry.
12. Bristlenose Pleco (in larger tanks)
- Temperament: Peaceful bottom feeder
- Tank Size: 30 gallons minimum
- Why They’re Compatible: Non-interactive and useful for algae control
Not ideal for small tanks, but they work great in planted setups with space. Bristlenose plecos won’t bother your betta.

Species to Avoid as Betta Tank Mates
Some fish just don’t work with bettas. Here’s a quick list of common incompatible species:
- Male Guppies: Their bright tails provoke aggression.
- Tiger Barbs: Known fin-nippers, they’ll shred your betta.
- Goldfish: Different water requirements and too messy.
- Gouramis: Too similar in behavior and may cause fights.
- Large Cichlids: Overly aggressive and territorial.
Tips for Introducing Tank Mates to Your Betta
Adding tank mates isn’t just about picking the right species—it’s about smart introduction and observation. Here’s how to ensure peaceful coexistence:
- Use a divided tank: Let the betta see new tank mates before releasing them.
- Rearrange decorations: Break up established territory to reduce aggression.
- Feed all fish well: Hungry bettas are more likely to attack.
- Monitor behavior: Watch for flaring, chasing, or fin nipping.
Tank Setup Tips for a Peaceful Betta Community
Setting up your tank the right way makes a huge difference. Use these tips to create a stress-free environment:
- Provide plants and cover: Live or silk plants, caves, and driftwood help break sightlines.
- Use gentle filtration: Bettas prefer calm waters.
- Keep water conditions stable: Maintain a temperature of 76–80°F and pH between 6.5 and 7.5.
- Avoid overstocking: Give everyone enough space to retreat and breathe.
Conclusion: Build the Perfect Betta Community
Bettas can thrive with tank mates when you choose wisely and manage the environment carefully. With the right balance of companions, plants, and space, your betta will become more active, confident, and healthy.
Whether you add peaceful schooling fish, quirky bottom dwellers, or useful invertebrates, your betta tank can become a vibrant and dynamic habitat that’s a joy to watch.
