Can Marbled Crayfish live with Siamese Algae Eater?
Caution — with care
Why
- Marbled Crayfish can grab Siamese Algae Eater while it sleeps — only fast mid/top-water fish are reasonably safe.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
Sweet spot: both do well at 72–77°F and pH 6.5–7.6 — aim there.
