Can Noble Gourami live with Dwarf Emerald Rasbora (nanus)?
Caution — with care
Why
- Very different sizes (Noble Gourami 3" vs Dwarf Emerald Rasbora (nanus) 0.7") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
Sweet spot: both do well at 72–75°F and pH 6.5–7.5 — aim there.
