Can platies and fancy goldfish live together?
With care
Platies and fancy goldfish can share a tank, but there is something to watch.
Why
- Goldfish are slow, messy, cold-water fish. They do best in a tank with other goldfish.
What each one needs
| Platy | Fancy goldfish | Both | |
|---|---|---|---|
| Temperature | 70–80°F (21–27°C) | 65–72°F (18–22°C) | 70–72°F (21–22°C) |
| pH | 7.0–8.2 | 7.0–8.0 | 7.0–8.0 |

The smallest tank for both
A 29 gallons (110 L) tank holds 3 platies and 1 fancy goldfish at about 67% of its stocking limit, which leaves room for more.
