Can Blue Bolt Shrimp live with Marbled Crayfish?
Not recommended
Why
- Marbled Crayfish hunts shrimp and is 5.0× the length of Blue Bolt Shrimp — it will eat them.
- Marbled Crayfish is one of the animals to keep away from a breeding shrimp colony — either it hunts them, or it out-competes and harasses them until the colony stops replacing itself. A Blue Bolt Shrimp colony will not hold its numbers.
- Only a narrow pH overlap — keep both around 6.5–6.6.
- Only a narrow water hardness overlap — keep both around 5–5 dGH.
