Can Cajun Dwarf Crayfish live with Noble Gourami?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
- Cajun Dwarf Crayfish can grab Noble Gourami while it sleeps — only fast mid/top-water fish are reasonably safe.
Sweet spot: both do well at 65–75°F and pH 6.5–7.6 — aim there.
