Can Fancy Guppy (Female trio) live with Pygmy Rasbora?
Light caution
Why
- Only a narrow pH overlap — keep both around 6.8–7.
- Only a narrow water hardness overlap — keep both around 8–8 dGH.
- Large size gap (Fancy Guppy (Female trio) 2.4" vs Pygmy Rasbora 0.8") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 75–82°F and pH 6.8–7 — aim there.
