Can pygmy corydoras and kuhli loaches live together?
Yes
Pygmy corydoras and kuhli loaches can share a tank. Their water needs overlap and neither is known to bother the other.
Why
- Their temperature and pH ranges overlap comfortably, and neither is known to nip, chase or eat the other.
What each one needs
| Pygmy corydoras | Kuhli loach | Both | |
|---|---|---|---|
| Temperature | 72–79°F (22–26°C) | 75–86°F (24–30°C) | 75–79°F (24–26°C) |
| pH | 6.4–7.4 | 5.5–7.0 | 6.4–7.0 |
| Minimum tank | 10 gal (38 L) | 20 gal (76 L) | 20 gal (76 L) |
| Keep at least | 6 | 5 | |
| Adult size | 1 in (2.5 cm) | 4 in (10.2 cm) |
The smallest tank for both
A 20 gallons (76 L) tank holds 6 pygmy corydoras and 5 kuhli loaches at about 53% of its stocking limit, which leaves room for more.
