Can Cajun Dwarf Crayfish live with Ghost Shrimp?
Caution — with care
Why
- Cajun Dwarf Crayfish 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 65–75°F and pH 6.5–8 — aim there.
