Can Tiger Shrimp live with Yucatan Molly?
Not recommended
Why
- Yucatan Molly is 6.0× the length of Tiger Shrimp — easily mouth-sized, and anything that fits in the mouth is a predator.
- Yucatan Molly is not on the verified shrimp-safe list, so we will not recommend it over a breeding Tiger Shrimp colony. It may well be fine — it simply has not been confirmed by a source, and an unverified guess is not worth the colony.
- No overlapping pH: Tiger Shrimp wants 6.2–7.2 but Yucatan Molly wants 7.5–8.5.
- No overlapping water hardness: Tiger Shrimp wants 3–8 dGH but Yucatan Molly wants 15–30 dGH.
