Can Wild Betta Splendens live with Dwarf Crayfish (CPO)?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Dwarf Crayfish (CPO) can grab Wild Betta Splendens while it sleeps — only fast mid/top-water fish are reasonably safe.
Sweet spot: both do well at 75–79°F and pH 7–7.6 — 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.
- Only combine with fast, mid/top-water fish and give the tankmates plenty of escape routes.
