Can ember tetras and male bettas live together?
Yes
Ember tetras 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
| Ember tetra | Betta (male) | Both | |
|---|---|---|---|
| Temperature | 73–84°F (23–29°C) | 76–82°F (24–28°C) | 76–82°F (24–28°C) |

The smallest tank for both
A 10 gallons (38 L) tank holds 6 ember tetras and 1 betta (male) at about 44% of its stocking limit, which leaves room for more.
