Can Dwarf Gourami Live With Molly?
Maybe, with caveats -- dwarf gouramis and mollies share water ranges, but dwarf gouramis are shy while mollies are active and may cause stress.
Why
- Dwarf gouramis grow to 2 inches and prefer calm tank areas near the surface with dense plant cover.
- Mollies reach 4 to 5 inches and are active swimmers that may crowd out a timid dwarf gourami.
- Both species tolerate temperatures from 72-82F and pH from 7.0-7.5, so water conditions are compatible.
- A 20-gallon tank with plenty of plants gives dwarf gouramis retreat zones away from molly traffic.
What could go wrong
Mollies may outcompete dwarf gouramis for food at the surface, leaving gouramis stressed and underfed.
Gear for a shared tank

AquaClear 30 Power Filter
Oversized filtration is what lets you stock two species together without water quality crashing. Rated for a tank slightly larger than the 20 gallon minimum.
Eheim Jager 150W Thermostat Heater
Holds a steady temperature inside the 72-82°F window both species need.
API Freshwater Master Test Kit
Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
Dwarf gouramis do well with peaceful tetras or corydoras; mollies do well with platies or swordtails.
