Can Platy live with Cardinal Sulawesi Shrimp?
Light caution
Why
- Platy leaves adult Cardinal Sulawesi Shrimp alone but eats the babies — the colony survives with plenty of cover.
- No overlapping water hardness: Platy wants 10–28 dGH but Cardinal Sulawesi Shrimp wants 4–8 dGH.
Sweet spot: both do well at 79–82°F and pH 7.5–8.2 — aim there.
Side-by-side
| Platy | Cardinal Sulawesi Shrimp | |

Together, plan on at least 15 gallons.
How to make it work
- Keep a large, established shrimp colony in a heavily planted tank with moss and cover so enough survive to breed.
- Target the overlapping water-parameter range and acclimate slowly.
