Can Electric Blue Crayfish live with Green Neon Tetra?
Caution — with care
Why
- Electric Blue Crayfish can grab Green Neon Tetra while it sleeps — only fast mid/top-water fish are reasonably safe.
- Only a narrow pH overlap — keep both around 6.5.
- Only a narrow water hardness overlap — keep both around 5 dGH.
Sweet spot: both do well at 75–77°F and pH 6.5–6.5 — aim there.
