Can bristlenose plecos and tiger barbs live together?
Yes
Bristlenose plecos and tiger barbs 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
| Bristlenose pleco | Tiger barb | Both | |
|---|---|---|---|
| Temperature | 73–81°F (23–27°C) | 68–79°F (20–26°C) | 73–79°F (23–26°C) |
| pH | 6.5–7.5 | 6.0–7.5 | 6.5–7.5 |
| Minimum tank | 29 gal (110 L) | 20 gal (76 L) | 29 gal (110 L) |
| Keep at least | 1 | 6 | |
| Adult size | 5 in (12.7 cm) | 2.8 in (7.1 cm) |
The smallest tank for both
A 29 gallons (110 L) tank holds 1 bristlenose pleco and 6 tiger barbs at about 59% of its stocking limit, which leaves room for more.
