Can Pom Pom Crab live with Red-Line Rasbora?
Light caution
Why
- Pom Pom Crab can grab Red-Line Rasbora while it sleeps — only fast mid/top-water fish are reasonably safe.
- Only a narrow pH overlap — keep both around 7–7.
- Only a narrow water hardness overlap — keep both around 6–8 dGH.
Sweet spot: both do well at 73–81°F and pH 7–7 — aim there.
