Can Wild-Type Betta live with Cardinal Shrimp?
Caution — with care
Why
- Wild-Type Betta is one of the animals to keep away from a breeding shrimp colony — either it hunts them, or it out-competes and harasses them until the colony stops replacing itself. A Cardinal Shrimp colony will not hold its numbers.
- Bettas are notorious for hunting shrimp and Cardinal Shrimp is small enough to be worth chasing. Some individuals ignore them completely — provide heavy cover, and be ready to move one or the other.
- Wild-Type Betta will eat Cardinal Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
- Only a narrow pH overlap — keep both around 7.5–7.5.
Sweet spot: both do well at 79–82°F and pH 7.5–7.5 — aim there.
Side-by-side
| Wild-Type Betta | Cardinal Shrimp | |
|---|---|---|
| Temperature | 76–82°F | 79–84°F |
| pH | 6–7.5 | 7.5–8.5 |
| Hardness (GH) | 2–12 dGH | 8–18 dGH |
| Adult size | 2.5" | 0.8" |
| Temperament | Semi-aggressive | Peaceful |
| Min tank | 10 gal | 15 gal |
Together, plan on at least 15 gallons.
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.
Sort it with: GH remineraliser
