Can male bettas and pygmy corydoras live together?
Yes
Male bettas and pygmy corydoras 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
| Betta (male) | Pygmy corydoras | Both | |
|---|---|---|---|
| Temperature | 76–82°F (24–28°C) | 72–79°F (22–26°C) | 76–79°F (24–26°C) |
| pH | 6.5–7.5 | 6.4–7.4 | 6.5–7.4 |
| Minimum tank | 5 gal (19 L) | 10 gal (38 L) | 10 gal (38 L) |
| Keep at least | 1 | 6 | |
| Adult size | 2.5 in (6.4 cm) | 1 in (2.5 cm) |
The smallest tank for both
A 10 gallons (38 L) tank holds 1 betta (male) and 6 pygmy corydoras at about 50% of its stocking limit, which leaves room for more.
