Can mollies and dwarf gouramis live together?
With care
Mollies and dwarf gouramis can share a tank, but there is something to watch.
Why
- Their pH ranges only meet at 7.5, which leaves no margin.
What each one needs
| Molly | Dwarf gourami | Both | |
|---|---|---|---|
| Temperature | 72–82°F (22–28°C) | 72–82°F (22–28°C) | 72–82°F (22–28°C) |
| pH | 7.5–8.5 | 6.0–7.5 | 7.5–7.5 |
| Minimum tank | 20 gal (76 L) | 10 gal (38 L) | 20 gal (76 L) |
| Keep at least | 3 | 1 | |
| Adult size | 4 in (10.2 cm) | 3.5 in (8.9 cm) |
The smallest tank for both
A 20 gallons (76 L) tank holds 3 mollies and 1 dwarf gourami at about 60% of its stocking limit, which leaves room for more.
