Can Emerald Dwarf Rasbora live with Brilliant Rasbora?
Caution — with care
Why
- Very different sizes (Brilliant Rasbora 4" vs Emerald Dwarf Rasbora 0.9") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Only a narrow pH overlap — keep both around 7–7.
Sweet spot: both do well at 72–77°F and pH 7–7 — aim there.
