Can Cherry Barb live with Yucatan Molly?
Light caution
Why
- Only a narrow pH overlap — keep both around 7.5–7.5.
- Only a narrow water hardness overlap — keep both around 15–15 dGH.
- Large size gap (Yucatan Molly 6" vs Cherry Barb 2") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 73–81°F and pH 7.5–7.5 — aim there.
