Can Electric Blue Crayfish live with Moonlight Gourami?
Caution — with care
Why
- Electric Blue Crayfish can grab Moonlight Gourami while it sleeps — only fast mid/top-water fish are reasonably safe.
- Almost no shared temperature: Electric Blue Crayfish wants 65–77°F and Moonlight Gourami wants 77–86°F, so only 77°F suits both — too fine a margin to actually hold.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
Sweet spot: both do well at 77–77°F and pH 6.5–7.6 — aim there.
Side-by-side
| Electric Blue Crayfish | Moonlight Gourami | |
|---|---|---|
| Temperature | 65–77°F | 77–86°F |
| pH | 6.5–8 | 6.5–7.6 |
| Hardness (GH) | 5–15 dGH | 6–7.5 dGH |
| Adult size | 5" | 6" |
| Temperament | Aggressive | Peaceful |
| Min tank | 30 gal | 55 gal |
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.
