Can Dwarf Emerald Rasbora live with Brilliant Rasbora?
Light caution
Why
- Only a narrow pH overlap — keep both around 7–7.
- Large size gap (Brilliant Rasbora 4" vs Dwarf Emerald Rasbora 1") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 72–78°F and pH 7–7 — aim there.
