Can Fiddler Crab live with Yellow King Kong Shrimp?
Caution — with care
Why
- Fiddler Crab is not on the verified shrimp-safe list, so we will not recommend it over a breeding Yellow King Kong Shrimp colony. It may well be fine — it simply has not been confirmed by a source, and an unverified guess is not worth the colony.
- Fiddler Crab hunts shrimp. Yellow King Kong Shrimp is large enough to be awkward prey, but not safe.
- No overlapping pH: Fiddler Crab wants 7.5–8.5 but Yellow King Kong Shrimp wants 5.8–6.6.
- No overlapping water hardness: Fiddler Crab wants 15–25 dGH but Yellow King Kong Shrimp wants 2–5 dGH.
- Fiddler Crab will eat Yellow King Kong Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
Side-by-side
| Fiddler Crab | Yellow King Kong Shrimp | |

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
