Can Fiddler Crab live with Sparkling Gourami?
Caution — with care
Why
- Fiddler Crab can grab Sparkling Gourami while it sleeps — only fast mid/top-water fish are reasonably safe.
- No overlapping water hardness: Fiddler Crab wants 15–25 dGH but Sparkling Gourami wants 2–12 dGH.
- Only a narrow pH overlap — keep both around 7.5–7.5.
Sweet spot: both do well at 76–82°F and pH 7.5–7.5 — aim there.
