Can Pygmy Cory live with Zebra Pleco?
Caution — with care
Why
- Only a narrow temperature overlap — keep both around 79°F.
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
- Large size gap (Pygmy Cory 1" vs Zebra Pleco 3.5") — the bigger fish may eat the smaller one as they grow.
Sweet spot: both do well at 79–79°F and pH 6.5–7.5 — aim there.
