Can Emerald Dwarf Rasbora live with Noble Gourami?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
- Large size gap (Noble Gourami 3" vs Emerald Dwarf Rasbora 0.9") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 68–75°F and pH 7–7.6 — aim there.
