Can Wild-Type Betta live with Moonlight Gourami?
Caution — with care
Why
- Wild-Type Betta and Moonlight 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 6–7.5 dGH.
- Wild-Type Betta is semi-aggressive — give the peaceful Moonlight Gourami plenty of space, cover and broken sight lines.
Sweet spot: both do well at 77–82°F and pH 6.5–7.5 — aim there.

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.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
- Target the overlapping water-parameter range and acclimate slowly.
