Can Electric Blue Crayfish live with Super Crystal Red Shrimp?
Not recommended
Why
- Electric Blue Crayfish hunts shrimp and is 4.2× the length of Super Crystal Red 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 Super Crystal Red Shrimp colony will not hold its numbers.
- No overlapping water hardness: Electric Blue Crayfish wants 5–15 dGH but Super Crystal Red Shrimp wants 0–4 dGH.
- Electric Blue Crayfish will eat Super Crystal Red 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 6.5–6.8.
