Can Guppy live with Cardinal Sulawesi Shrimp?
Caution — with care
Why
- Only a narrow pH overlap — keep both around 7.5–7.8.
- Only a narrow water hardness overlap — keep both around 8 dGH.
- Guppy leaves adult Cardinal Sulawesi Shrimp alone but eats the babies — the colony survives with plenty of cover.
Sweet spot: both do well at 79–82°F and pH 7.5–7.8 — 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.
