Can Moonlight Gourami live with Green Neon Tetra?
Caution — with care
Why
- No overlapping water hardness: Moonlight Gourami wants 6–7.5 dGH but Green Neon Tetra wants 1–5 dGH.
- Very different sizes (Moonlight Gourami 6" vs Green Neon Tetra 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 6.5–6.5.
Sweet spot: both do well at 77–84°F and pH 6.5–6.5 — aim there.
Side-by-side
| Moonlight Gourami | Green Neon Tetra | |
|---|---|---|
| Temperature | 77–86°F | 75–84°F |
| pH | 6.5–7.6 | 4–6.5 |
| Hardness (GH) | 6–7.5 dGH | 1–5 dGH |

Together, plan on at least 55 gallons.
How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
