Can Molly Live With Pearl Gourami?
Maybe, with caveats -- pearl gouramis and mollies share the upper end of each other temperature range, but pearl gouramis are docile and mollies can be pushy.
Why
- Pearl gouramis grow to 4 to 5 inches and are peaceful surface-dwellers that do best with calm tankmates.
- Mollies reach 4 to 5 inches and are active swimmers that may crowd out a timid pearl gourami.
- Both species tolerate temperatures from 77-82F and pH from 7.0-8.0, making water conditions compatible at the warmer end.
- A 30-gallon tank gives pearl gouramis room to establish territory and provides enough swimming space for mollies.
What could go wrong
Mollies may outcompete pearl gouramis for food at the surface, leaving the gourami underfed and stressed.
Gear for a shared tank

AquaClear 70 Power Filter
Oversized filtration is what lets you stock two species together without water quality crashing. Rated for a tank slightly larger than the 30 gallon minimum.
Eheim Jager 200W Thermostat Heater
Holds a steady temperature inside the 77-82°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
Pearl gouramis do well with peaceful tetras or corydoras; mollies do well with platies or swordtails.
