Can Marbled Crayfish live with Sparkling Gourami?
Caution — with care
Why
- Marbled Crayfish can grab Sparkling Gourami while it sleeps — only fast mid/top-water fish are reasonably safe.
- Only a narrow temperature overlap — keep both around 76–77°F.
Sweet spot: both do well at 76–77°F and pH 6.5–7.5 — aim there.
