Can Pearl Gourami live with Neon Blue Rasbora?
Caution — with care
Why
- Very different sizes (Pearl Gourami 4.5" vs Neon Blue Rasbora 0.8") — 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 5–5 dGH.
Sweet spot: both do well at 77–79°F and pH 6–6.5 — aim there.
