Can False Rummy Nose Tetra live with Molly?
Caution — with care
Why
- Only a narrow pH overlap — keep both around 7.
- Molly is large enough to threaten a small False Rummy Nose Tetra — usually fine once both are adult, but watch new additions.
- No overlapping water hardness: False Rummy Nose Tetra wants 2–8 dGH but Molly wants 12–30 dGH.
Sweet spot: both do well at 75–82°F and pH 7–7 — aim there.
