Can Neon Green Rasbora live with Yucatan Molly?
Caution — with care
Why
- No overlapping water hardness: Neon Green Rasbora wants 2–10 dGH but Yucatan Molly wants 15–30 dGH.
- Very different sizes (Yucatan Molly 6" vs Neon Green Rasbora 0.8") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Only a narrow pH overlap — keep both around 7.5–7.5.
Sweet spot: both do well at 72–79°F and pH 7.5–7.5 — aim there.
