Can Thai Devil Crab live with Neon Green Rasbora?
Caution — with care
Why
- Thai Devil Crab can grab Neon Green Rasbora while it sleeps — only fast mid/top-water fish are reasonably safe.
- Only a narrow pH overlap — keep both around 7.5–7.5.
- Only a narrow water hardness overlap — keep both around 8–10 dGH.
Sweet spot: both do well at 75–79°F and pH 7.5–7.5 — aim there.
