Can Panther Crab live with Yucatan Molly?
Caution — with care
Why
- Panther Crab can grab Yucatan Molly while it sleeps — only fast mid/top-water fish are reasonably safe.
- Only a narrow water hardness overlap — keep both around 15 dGH.
Sweet spot: both do well at 75–82°F and pH 7.5–8 — aim there.
