Can Electric Blue Crayfish live with Cardinal Shrimp?
Not recommended
Why
- Electric Blue Crayfish hunts shrimp and is 6.3× the length of Cardinal Shrimp — it will eat them.
- Electric Blue 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 Cardinal Shrimp colony will not hold its numbers.
- No overlapping temperature: Electric Blue Crayfish wants 65–77°F but Cardinal Shrimp wants 79–84°F.
