Can Discus live with Electric Blue Crayfish?
Caution — with care
Why
- Electric Blue Crayfish can grab Discus while it sleeps — only fast mid/top-water fish are reasonably safe.
- No overlapping temperature: Discus wants 82–88°F but Electric Blue Crayfish wants 65–77°F.
Side-by-side

Together, plan on at least 55 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.
