Can Lambchop Rasbora live with Molly?
Caution — with care
Why
- Molly may eat Lambchop Rasbora; add only full-grown adults, because juveniles and fry will be picked off.
- Only a narrow pH overlap — keep both around 7.
- No overlapping water hardness: Lambchop Rasbora wants 2–10 dGH but Molly wants 12–30 dGH.
Sweet spot: both do well at 73–82°F and pH 7–7 — aim there.
