Can Kissing Gourami live with Neon Blue Rasbora?
Caution — with care
Why
- No overlapping water hardness: Kissing Gourami wants 6–8 dGH but Neon Blue Rasbora wants 1–5 dGH.
- Very different sizes (Kissing Gourami 12" 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 pH overlap — keep both around 6.5–6.5.
- Kissing Gourami is semi-aggressive — give the peaceful Neon Blue Rasbora plenty of space, cover and broken sight lines.
Sweet spot: both do well at 72–79°F and pH 6.5–6.5 — aim there.

How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
