Can Dwarf Emerald Rasbora (nanus) live with Platy?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 10–12 dGH.
- Large size gap (Platy 2.5" vs Dwarf Emerald Rasbora (nanus) 0.7") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 72–79°F and pH 7–7.5 — aim there.
