Can Black King Kong Shrimp live with Carnival / Polka Dot Freshwater Crab?
Caution — with care
Why
- Carnival / Polka Dot Freshwater Crab is not on the verified shrimp-safe list, so we will not recommend it over a breeding Black 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.
- Carnival / Polka Dot Freshwater Crab hunts shrimp. Black King Kong Shrimp is large enough to be awkward prey, but not safe.
- No overlapping temperature: Black King Kong Shrimp wants 68–74°F but Carnival / Polka Dot Freshwater Crab wants 75–82°F.
- No overlapping pH: Black King Kong Shrimp wants 5.8–6.6 but Carnival / Polka Dot Freshwater Crab wants 7.5–8.
- No overlapping water hardness: Black King Kong Shrimp wants 2–5 dGH but Carnival / Polka Dot Freshwater Crab wants 8–15 dGH.
- Carnival / Polka Dot Freshwater Crab will eat Black King Kong Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
