Can Marbled Crayfish live with Zebra Pleco?

Why
- Marbled Crayfish hunts along the bottom and will catch the bottom-dwelling Zebra Pleco, especially at night.
- No overlapping temperature: Marbled Crayfish wants 64–77°F but Zebra Pleco wants 79–86°F.
- Only a narrow water hardness overlap — keep both around 5–6 dGH.
