Can Cajun Dwarf Crayfish live with Moonlight Gourami?
Caution — with care
Why
- No overlapping temperature: Cajun Dwarf Crayfish wants 65–75°F but Moonlight Gourami wants 77–86°F.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Cajun Dwarf Crayfish can grab Moonlight Gourami while it sleeps — only fast mid/top-water fish are reasonably safe.
