Expert Care Tips for Platy
- Nano tank suitable: Platy can thrive in smaller tanks (10+ gal), but skip the bowl — even small fish need filtration and a heater.
- Tropical range: Keep Platy at 70–77°F. A 50W heater per 10 gallons is a safe rule of thumb for stable temperature.
- Narrow pH tolerance: Platy only tolerates pH 7.0–8.0. Test your tap water before buying — adjusting pH is harder than choosing the right fish for your water.
- Peaceful community fish: Platy works well in community tanks. Still, avoid housing with fish large enough to eat them — a 2.5" fish is vulnerable to anything with a mouth bigger than 2×.
- Acclimation: Always drip-acclimate Platy over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
