Can Kissing Gourami live with Guppy?
Caution — with care
Why
- Very different sizes (Kissing Gourami 12" vs Guppy 2") — 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 8–8 dGH.
- Kissing Gourami is semi-aggressive — give the peaceful Guppy plenty of space, cover and broken sight lines.
Sweet spot: both do well at 72–82°F and pH 6.8–7.6 — aim there.
Side-by-side
| Kissing Gourami | Guppy | |
|---|---|---|
| Temperature | 72–82°F | 72–82°F |
| pH | 6.5–7.6 | 6.8–7.8 |
| Hardness (GH) | 6–8 dGH | 8–20 dGH |
| Adult size | 12" | 2" |
| Temperament | Semi-aggressive | Peaceful |
| Min tank | 75 gal | 10 gal |
Together, plan on at least 75 gallons.
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.
