Can Carnival / Polka Dot Freshwater Crab live with Chocolate Shrimp?
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 Chocolate 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. Chocolate Shrimp is large enough to be awkward prey, but not safe.
- Carnival / Polka Dot Freshwater Crab will eat Chocolate Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
Sweet spot: both do well at 75–80°F and pH 7.5–8 — aim there.
