Can pygmy corydoras and otocinclus live together?
Yes
Pygmy corydoras and otocinclus 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 | Otocinclus | Both | |
|---|---|---|---|
| Temperature | 72–79°F (22–26°C) | 72–79°F (22–26°C) | 72–79°F (22–26°C) |
| pH | 6.4–7.4 | 6.0–7.5 | 6.4–7.4 |
| Minimum tank | 10 gal (38 L) | 10 gal (38 L) | 10 gal (38 L) |
| Keep at least | 6 | 4 | |
| Adult size | 1 in (2.5 cm) | 1.8 in (4.6 cm) |
The smallest tank for both
A 10 gallons (38 L) tank holds 6 pygmy corydoras and 4 otocinclus at about 70% of its stocking limit, which leaves room for more.
