Can Fiddler Crab live with Zebra Pleco?
Not recommended
Why
- Fiddler Crab hunts along the bottom and will catch the bottom-dwelling Zebra Pleco, especially at night.
- No overlapping water hardness: Fiddler Crab wants 15–25 dGH but Zebra Pleco wants 2–6 dGH.
- Only a narrow pH overlap — keep both around 7.5–7.5.
