Can guppies and bristlenose plecos live together?
Yes
Guppies and bristlenose plecos 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
| Guppy | Bristlenose pleco | Both | |
|---|---|---|---|
| Temperature | 72–82°F (22–28°C) | 73–81°F (23–27°C) | 73–81°F (23–27°C) |
| pH | 6.8–7.8 | 6.5–7.5 | 6.8–7.5 |

The smallest tank for both
A 29 gallons (110 L) tank holds 3 guppies and 1 bristlenose pleco at about 28% of its stocking limit, which leaves room for more.
