Can Marbled Crayfish live with Red Nose Shrimp?
Not recommended
Why
- Marbled Crayfish hunts shrimp and is 3.3× the length of Red Nose Shrimp — it will eat them.
- Marbled Crayfish does not belong with Red Nose Shrimp. Puffers and crayfish are built to eat invertebrates and will take shrimp whatever the size difference — a pea puffer is smaller than an amano and still hunts it — and goldfish both harass shrimp and want cooler water. Keep them in separate tanks.
