Can mollies and nerite snails live together?
Yes
Mollies and nerite snails 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
| Molly | Nerite snail | Both | |
|---|---|---|---|
| Temperature | 72–82°F (22–28°C) | 72–78°F (22–26°C) | 72–78°F (22–26°C) |
| pH | 7.5–8.5 | 7.0–8.5 | 7.5–8.5 |
| Minimum tank | 20 gal (76 L) | 5 gal (19 L) | 20 gal (76 L) |
| Keep at least | 3 | 1 | |
| Adult size | 4 in (10.2 cm) | 1 in (2.5 cm) |
The smallest tank for both
A 20 gallons (76 L) tank holds 3 mollies and 1 nerite snail at about 48% of its stocking limit, which leaves room for more.
