Can platies and bristlenose plecos live together?
Yes
Platies 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
| Platy | Bristlenose pleco | Both | |
|---|---|---|---|
| Temperature | 70–80°F (21–27°C) | 73–81°F (23–27°C) | 73–80°F (23–27°C) |
| pH | 7.0–8.2 | 6.5–7.5 | 7.0–7.5 |
| Minimum tank | 10 gal (38 L) | 29 gal (110 L) | 29 gal (110 L) |
| Keep at least | 3 | 1 | |
| Adult size | 2.5 in (6.4 cm) | 5 in (12.7 cm) |
The smallest tank for both
A 29 gallons (110 L) tank holds 3 platies and 1 bristlenose pleco at about 33% of its stocking limit, which leaves room for more.
