Can Red Claw Crab live with Tangerine Tiger Shrimp?
Caution — with care
Why
- Red Claw Crab is not on the verified shrimp-safe list, so we will not recommend it over a breeding Tangerine 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 Claw Crab hunts shrimp. Tangerine Tiger Shrimp is large enough to be awkward prey, but not safe.
- No overlapping pH: Red Claw Crab wants 7.5–8.5 but Tangerine Tiger Shrimp wants 5.8–6.8.
- No overlapping water hardness: Red Claw Crab wants 15–25 dGH but Tangerine Tiger Shrimp wants 3–6 dGH.
- Red Claw Crab will eat Tangerine Tiger Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
- Only a narrow temperature overlap — keep both around 75–76°F.
Side-by-side
| Red Claw Crab | Tangerine Tiger Shrimp | |
|---|---|---|
| Temperature | 75–82°F | 68–76°F |
| pH | 7.5–8.5 | 5.8–6.8 |
| Hardness (GH) | 15–25 dGH | 3–6 dGH |
| Adult size | 2.5" | 1" |
| Temperament | Semi-aggressive | Peaceful |
| Min tank | 15 gal | 5 gal |
Together, plan on at least 15 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 · An adjustable heater
