Can Emerald Dwarf Rasbora live with Discus?
Caution — with care
Why
- No overlapping temperature: Emerald Dwarf Rasbora wants 68–77°F but Discus wants 82–88°F.
- Very different sizes (Discus 8" 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.
