Can Pom Pom Crab live with Rummynose Tetra?
Caution — with care
Why
- Only a narrow pH overlap — keep both around 7.
- Only a narrow water hardness overlap — keep both around 6–8 dGH.
- Pom Pom Crab can grab Rummynose Tetra while it sleeps — only fast mid/top-water fish are reasonably safe.
Sweet spot: both do well at 75–82°F and pH 7–7 — aim there.
