Can Betta (Siamese Fighting Fish) live with Endler's Livebearer?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 10–12 dGH.
- Betta (Siamese Fighting Fish) is semi-aggressive — give the peaceful Endler's Livebearer plenty of space, cover and broken sight lines.
Sweet spot: both do well at 76–82°F and pH 7–7.5 — aim there.

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.
