Can Julii Cory live with Red Claw Crab?
Not recommended
Why
- Red Claw Crab hunts along the bottom and will catch the bottom-dwelling Julii Cory, especially at night.
- No overlapping water hardness: Julii Cory wants 2–12 dGH but Red Claw Crab wants 15–25 dGH.
- Only a narrow pH overlap — keep both around 7.5–7.8.
