Can Flower Shrimp live with Yucatan Molly?
Caution — with care
Why
- Only a narrow pH overlap — keep both around 7.5.
- Yucatan Molly eats dwarf shrimp, but Flower Shrimp grows to 2.5" — big enough to be safe with dense cover.
- No overlapping water hardness: Flower Shrimp wants 5–12 dGH but Yucatan Molly wants 15–30 dGH.
Sweet spot: both do well at 72–79°F and pH 7.5–7.5 — aim there.

How to make it work
