Can chili rasboras and male bettas live together?
Yes
Chili rasboras and male bettas 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
| Chili rasbora | Betta (male) | Both | |
|---|---|---|---|
| Temperature | 68–82°F (20–28°C) | 76–82°F (24–28°C) | 76–82°F (24–28°C) |
| pH | 4.0–7.0 | 6.5–7.5 | 6.5–7.0 |
| Minimum tank | 5 gal (19 L) | 5 gal (19 L) | 5 gal (19 L) |
| Keep at least | 6 | 1 | |
| Adult size | 0.7 in (1.8 cm) | 2.5 in (6.4 cm) |
The smallest tank for both
A 5 gallons (19 L) tank holds 6 chili rasboras and 1 betta (male) at about 76% of its stocking limit, which leaves room for more.
