Can Ghost Shrimp live with Dwarf Crayfish (CPO)?
Caution — with care
Why
- Dwarf Crayfish (CPO) does not belong with Ghost 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.
Sweet spot: both do well at 65–79°F and pH 7–8 — aim there.
