Can Discus live with Neon Blue Rasbora?
Caution — with care
Why
- No overlapping temperature: Discus wants 82–88°F but Neon Blue Rasbora wants 72–79°F.
- Very different sizes (Discus 8" vs Neon Blue Rasbora 0.8") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
