Can Julii Cory live with Yucatan Molly?
Caution — with care
Why
- No overlapping water hardness: Julii Cory wants 2–12 dGH but Yucatan Molly wants 15–30 dGH.
- Only a narrow pH overlap — keep both around 7.5–7.8.
- Large size gap (Yucatan Molly 6" vs Julii Cory 2") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 72–79°F and pH 7.5–7.8 — aim there.
