Can Tiger Shrimp live with Red Devil Vampire Crab?
Caution — with care
Why
- Red Devil Vampire Crab is not on the verified shrimp-safe list, so we will not recommend it over a breeding Tiger 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.
- Red Devil Vampire Crab hunts shrimp. Tiger Shrimp is large enough to be awkward prey, but not safe.
- No overlapping pH: Tiger Shrimp wants 6.2–7.2 but Red Devil Vampire Crab wants 7.5–8.
- Red Devil Vampire Crab will eat Tiger Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
- Only a narrow water hardness overlap — keep both around 8–8 dGH.
Side-by-side
| Tiger Shrimp | Red Devil Vampire Crab | |
|---|---|---|
| Temperature | 68–77°F | 75–82°F |
| pH | 6.2–7.2 | 7.5–8 |
| Hardness (GH) | 3–8 dGH | 8–15 dGH |
| Adult size | 1" | 1.5" |
| Temperament | Peaceful | Peaceful |
| Min tank | 5 gal | 10 gal |
Together, plan on at least 10 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
