Can Wild-Type Betta live with Swordtail?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 12 dGH.
- Wild-Type Betta is semi-aggressive and may bully the peaceful Swordtail — give lots of space and cover.
- Swordtail is large enough to threaten a small Wild-Type Betta — usually fine once both are adult, but watch new additions.
Sweet spot: both do well at 76–82°F and pH 7–7.5 — aim there.
Side-by-side
| Wild-Type Betta | Swordtail | |
|---|---|---|
| Temperature | 76–82°F | 72–82°F |
| pH | 6–7.5 | 7–8.4 |

| Adult size | 2.5" | 5.5" |
| Temperament | Semi-aggressive | Peaceful |
| Min tank | 10 gal | 29 gal |
Together, plan on at least 29 gallons.
How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
- Keep a large, established shrimp colony in a heavily planted tank with moss and cover so enough survive to breed.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
