Can Fiddler Crab live with Typhoon Pleco?
Not recommended
Why
- Fiddler Crab hunts along the bottom and will catch the bottom-dwelling Typhoon Pleco, especially at night.
- No overlapping water hardness: Fiddler Crab wants 15–25 dGH but Typhoon Pleco wants 6–7.5 dGH.
- Only a narrow pH overlap — keep both around 7.5–7.6.
