Can Platy live with Pygmy Rasbora?
Caution — with care
Why
- No overlapping water hardness: Platy wants 10–28 dGH but Pygmy Rasbora wants 1–8 dGH.
- Only a narrow pH overlap — keep both around 7–7.
- Large size gap (Platy 2.5" 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 7–7 — aim there.
Side-by-side
| Platy | Pygmy Rasbora | |
|---|---|---|
| Temperature | 70–82°F | 75–82°F |

Together, plan on at least 15 gallons.
How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
