Can Cajun Dwarf Crayfish live with Vampire Shrimp?
Caution — with care
Why
- Only a narrow temperature overlap — keep both around 75°F.
- Cajun Dwarf Crayfish eats dwarf shrimp, but Vampire Shrimp grows to 6" — big enough to be safe with dense cover.
Sweet spot: both do well at 75–75°F and pH 6.5–7.5 — aim there.
