Can Ember Tetra live with Fancy Guppy (Female trio)?
Caution — with care
Why
- Only a narrow pH overlap — keep both around 6.8–7.
- Only a narrow water hardness overlap — keep both around 8 dGH.
- Large size gap (Ember Tetra 0.8" vs Fancy Guppy (Female trio) 2.4") — the bigger fish may eat the smaller one as they grow.
Sweet spot: both do well at 73–82°F and pH 6.8–7 — aim there.
