Can Ghost Shrimp live with Yucatan Molly?
Caution — with care
Why
- Yucatan Molly is 4.0× the length of Ghost Shrimp and big enough to swallow one. Some keepers get away with it in a heavily planted tank; it is a real risk.
- Only a narrow water hardness overlap — keep both around 15–15 dGH.
Sweet spot: both do well at 72–82°F and pH 7.5–8 — aim there.
Side-by-side

Together, plan on at least 40 gallons.
How to make it work
- Keep a large, established shrimp colony in a heavily planted tank with moss and cover so enough survive to breed.
- Add only full-grown adults — never juveniles, which will be eaten.
- Target the overlapping water-parameter range and acclimate slowly.
