Can neon tetras and guppies live together?
With care
Neon tetras and guppies can share a tank, but there is something to watch.
Why
- Their pH ranges overlap only between 6.8–7.0.
What each one needs
| Neon tetra | Guppy | Both | |
|---|---|---|---|
| Temperature | 70–81°F (21–27°C) | 72–82°F (22–28°C) | 72–81°F (22–27°C) |
| pH | 6.0–7.0 | 6.8–7.8 | 6.8–7.0 |
| Minimum tank | 10 gal (38 L) | 5 gal (19 L) | 10 gal (38 L) |
| Keep at least | 6 | 3 | |
| Adult size | 1.5 in (3.8 cm) | 2 in (5.1 cm) |
The smallest tank for both
A 10 gallons (38 L) tank holds 6 neon tetras and 3 guppies at about 78% of its stocking limit, which leaves room for more.
