Can Marbled Crayfish live with Colombian Zebra Pleco?
Not recommended
Why
- Marbled Crayfish hunts along the bottom and will catch the bottom-dwelling Colombian Zebra Pleco, especially at night.
- Almost no shared temperature: Marbled Crayfish wants 64–77°F and Colombian Zebra Pleco wants 77–82°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.
