Can Betta (Siamese Fighting Fish) live with Noble Gourami?
Caution — with care
Why
- No overlapping temperature: Betta (Siamese Fighting Fish) wants 76–82°F but Noble Gourami wants 64–75°F.
- Betta (Siamese Fighting Fish) and Noble Gourami are both labyrinth fish — they claim the same surface territory and will fight, especially between males.
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
- Betta (Siamese Fighting Fish) is semi-aggressive — give the peaceful Noble Gourami plenty of space, cover and broken sight lines.

How to make it work
- Keep a large, established shrimp colony in a heavily planted tank with moss and cover so enough survive to breed.
- Target the overlapping water-parameter range and acclimate slowly.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
