Can Wine Red Shrimp live with Thai Freshwater Crab?
Caution — with care
Why
- Thai Freshwater Crab is not on the verified shrimp-safe list, so we will not recommend it over a breeding Wine Red 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.
- Thai Freshwater Crab hunts shrimp. Wine Red Shrimp is large enough to be awkward prey, but not safe.
- Almost no shared temperature: Wine Red Shrimp wants 62–72°F and Thai Freshwater Crab wants 72–82°F, so only 72°F suits both — too fine a margin to actually hold.
- No overlapping pH: Wine Red Shrimp wants 5.8–6.8 but Thai Freshwater Crab wants 7–8.
- No overlapping water hardness: Wine Red Shrimp wants 0–4 dGH but Thai Freshwater Crab wants 6–15 dGH.
- Thai Freshwater Crab will eat Wine Red Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
Side-by-side
| Wine Red Shrimp | Thai Freshwater Crab | |
|---|---|---|
| Temperature | 62–72°F | 72–82°F |
| pH | 5.8–6.8 | 7–8 |
| Hardness (GH) | 0–4 dGH | 6–15 dGH |
| Adult size | 1.2" | 2.5" |
| Temperament | Peaceful | Semi-aggressive |
| Min tank | 10 gal | 15 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
