Can Flower Shrimp live with Purple Vampire Crab?
Light caution
Why
- Purple Vampire Crab hunts shrimp, though Flower Shrimp is nearly its own size — losses should be rare with cover.
- Only a narrow pH overlap — keep both around 7.5–7.5.
Sweet spot: both do well at 75–79°F and pH 7.5–7.5 — 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.
