Can Red Claw Crab live with Snowball 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 Snowball 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. Snowball Shrimp is large enough to be awkward prey, but not safe.
- No overlapping water hardness: Red Claw Crab wants 15–25 dGH but Snowball Shrimp wants 4–14 dGH.
- Red Claw Crab will eat Snowball 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 75–78°F and pH 7.5–7.8 — aim there.
Side-by-side
| Red Claw Crab | Snowball Shrimp | |
|---|---|---|
| Temperature | 75–82°F | 65–78°F |
| pH | 7.5–8.5 | 6.5–7.8 |
| Hardness (GH) | 15–25 dGH | 4–14 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
