Can Chocolate Gourami live with Electric Blue Crayfish?
Caution — with care
Why
- Electric Blue Crayfish can grab Chocolate Gourami while it sleeps — only fast mid/top-water fish are reasonably safe.
- No overlapping temperature: Chocolate Gourami wants 78–86°F but Electric Blue Crayfish wants 65–77°F.
- Only a narrow pH overlap — keep both around 6.5–6.5.
- Only a narrow water hardness overlap — keep both around 5–5 dGH.
Side-by-side

Together, plan on at least 30 gallons.
How to make it work
- Only combine with fast, mid/top-water fish and give the tankmates plenty of escape routes.
- Target the overlapping water-parameter range and acclimate slowly.
