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