Can Black Rose Shrimp live with Purple Vampire Crab?
Caution — with care
Why
- Purple Vampire Crab is not on the verified shrimp-safe list, so we will not recommend it over a breeding Black Rose 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.
- Almost no shared temperature: Black Rose Shrimp wants 65–75°F and Purple Vampire Crab wants 75–82°F, so only 75°F suits both — too fine a margin to actually hold.
- Purple Vampire Crab hunts shrimp, though Black Rose Shrimp is nearly its own size — losses should be rare with cover.
- Purple Vampire Crab will eat Black Rose 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 75–75°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.
Sort it with: An adjustable heater · GH remineraliser
