Can Least Rasbora live with Platy?
Caution — with care
Why
- No overlapping water hardness: Least Rasbora wants 1–8 dGH but Platy wants 10–28 dGH.
- Only a narrow pH overlap — keep both around 7–7.
- Large size gap (Platy 2.5" vs Least 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
| Least Rasbora | Platy | |
|---|---|---|
| Temperature | 75–82°F | 70–82°F |
| pH | 5–7 | 7–8.2 |
| Hardness (GH) | 1–8 dGH | 10–28 dGH |
| Adult size | 0.8" | 2.5" |
| Temperament | Peaceful | Peaceful |
| Min tank | 10 gal | 15 gal |
Together, plan on at least 15 gallons.
How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
