Can Purple Vampire Crab live with Yellow Neocaridina Shrimp?
Caution — with care
Why
- Purple Vampire Crab is not on the verified shrimp-safe list, so we will not recommend it over a breeding Yellow Neocaridina 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.
- Purple Vampire Crab hunts shrimp. Yellow Neocaridina Shrimp is large enough to be awkward prey, but not safe.
- Purple Vampire Crab will eat Yellow Neocaridina Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
- Only a narrow pH overlap — keep both around 7.5–7.8.
Sweet spot: both do well at 75–78°F and pH 7.5–7.8 — aim there.
Side-by-side
| Purple Vampire Crab | Yellow Neocaridina Shrimp | |
|---|---|---|
| Temperature | 75–82°F | 65–78°F |
| pH | 7.5–8 | 6.5–7.8 |

| Min tank | 20 gal | 5 gal |
Together, plan on at least 20 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
