Can Amano Shrimp live with Fiddler Crab?
Light caution
Why
- Fiddler Crab hunts shrimp, though Amano Shrimp is nearly its own size — losses should be rare with cover.
- Only a narrow pH overlap — keep both around 7.5–7.8.
- Only a narrow water hardness overlap — keep both around 15–15 dGH.
Sweet spot: both do well at 72–80°F and pH 7.5–7.8 — 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.
- Target the overlapping water-parameter range and acclimate slowly.
