Can guppies and cherry barbs live together?
Yes
Guppies and cherry 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
| Guppy | Cherry barb | 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 | 6.0–7.5 | 6.8–7.5 |
| Minimum tank | 5 gal (19 L) | 20 gal (76 L) | 20 gal (76 L) |
| Keep at least | 3 | 6 | |
| Adult size | 2 in (5.1 cm) | 2 in (5.1 cm) |
The smallest tank for both
A 20 gallons (76 L) tank holds 3 guppies and 6 cherry barbs at about 51% of its stocking limit, which leaves room for more.
