Can Blue Bolt Shrimp live with Thai Devil Crab?
Caution — with care
Why
- Thai Devil Crab is not on the verified shrimp-safe list, so we will not recommend it over a breeding Blue Bolt 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 Devil Crab hunts shrimp. Blue Bolt Shrimp is large enough to be awkward prey, but not safe.
- No overlapping temperature: Blue Bolt Shrimp wants 68–74°F but Thai Devil Crab wants 75–84°F.
- No overlapping pH: Blue Bolt Shrimp wants 5.8–6.6 but Thai Devil Crab wants 7.5–8.5.
- No overlapping water hardness: Blue Bolt Shrimp wants 2–5 dGH but Thai Devil Crab wants 8–18 dGH.
- Thai Devil Crab will eat Blue Bolt Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.

Together, plan on at least 20 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
