Can chili rasboras and otocinclus live together?
Yes
Chili rasboras 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
| Chili rasbora | Otocinclus | Both | |
|---|---|---|---|
| Temperature | 68–82°F (20–28°C) | 72–79°F (22–26°C) | 72–79°F (22–26°C) |
