Can Vampire Shrimp live with Yucatan Molly?
Caution — with care
Why
- Only a narrow pH overlap — keep both around 7.5.
- Only a narrow water hardness overlap — keep both around 15 dGH.
- Yucatan Molly eats dwarf shrimp, but Vampire Shrimp grows to 6" — big enough to be safe with dense cover.
Sweet spot: both do well at 75–82°F and pH 7.5–7.5 — aim there.
