Can Kissing Gourami live with Black Kuhli Loach?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 6–8 dGH.
- Kissing Gourami is semi-aggressive — give the peaceful Black Kuhli Loach plenty of space, cover and broken sight lines.
- Large size gap (Kissing Gourami 12" vs Black Kuhli Loach 3") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 73–82°F and pH 6.5–7 — aim there.

How to make it work
