Can guppies and kuhli loaches live together?
With care
Guppies and kuhli loaches 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
| Guppy | Kuhli loach | Both | |
|---|---|---|---|
| Temperature | 72–82°F (22–28°C) | 75–86°F (24–30°C) | 75–82°F (24–28°C) |
| pH | 6.8–7.8 | 5.5–7.0 | 6.8–7.0 |
| Minimum tank | 5 gal (19 L) | 20 gal (76 L) | 20 gal (76 L) |
| Keep at least | 3 | 5 | |
| Adult size | 2 in (5.1 cm) | 4 in (10.2 cm) |
The smallest tank for both
A 20 gallons (76 L) tank holds 3 guppies and 5 kuhli loaches at about 53% of its stocking limit, which leaves room for more.
