Can Green Neon Tetra live with Pearl Gourami?
Caution — with care
Why
- Very different sizes (Pearl Gourami 4.5" vs Green Neon Tetra 1") — 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 77–82°F and pH 6–6.5 — aim there.
Side-by-side
| Green Neon Tetra | Pearl Gourami | |
|---|---|---|
| Temperature | 75–84°F | 77–82°F |
| pH | 4–6.5 | 6–7.5 |
| Hardness (GH) | 1–5 dGH | 5–15 dGH |
| Adult size | 1" | 4.5" |
| Temperament | Peaceful | Peaceful |
| Min tank | 10 gal | 30 gal |
Together, plan on at least 30 gallons.
How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
