Can Kissing Gourami live with Marbled Crayfish?
Caution — with care
Why
- Marbled Crayfish can grab Kissing Gourami while it sleeps — only fast mid/top-water fish are reasonably safe.
- Only a narrow water hardness overlap — keep both around 6–8 dGH.
Sweet spot: both do well at 72–77°F and pH 6.5–7.6 — aim there.

How to make it work

- Target the overlapping water-parameter range and acclimate slowly.
