Can Discus live with Dwarf Emerald Rasbora?
Caution — with care
Why
- No overlapping temperature: Discus wants 82–88°F but Dwarf Emerald Rasbora wants 68–78°F.
- Very different sizes (Discus 8" vs Dwarf Emerald Rasbora 1") — 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.
