Can Red Devil Vampire Crab live with Vampire Shrimp?
Light caution
Why
- Red Devil Vampire Crab hunts shrimp, though Vampire Shrimp is nearly its own size — losses should be rare with cover.
- Only a narrow pH overlap — keep both around 7.5–7.5.
Sweet spot: both do well at 75–82°F and pH 7.5–7.5 — aim there.
