Can Pearl Gourami Live With Swordtail?
Maybe, with caveats. Pearl gouramis are larger and more hardy than dwarf gouramis, but male pearls can be territorial toward fish that enter their space.
Why
- Pearl gouramis reach 4-5 inches and are among the most peaceful large gouramis. Their size makes them less vulnerable to swordtails.
- Temperature overlap of 77-82°F and pH overlap of 7-8 work for both species. Pearl gouramis prefer the warmer end of the range.
- Male pearl gouramis establish territories during breeding and may chase swordtails that swim too close to their nest site.
- Pearl gouramis are slow-moving and may be outcompeted for food by active swordtails if the tank is too small.
- Pearl gouramis appreciate heavy planting and Décor that gives them hiding spots when they want to retreat.
What could go wrong
A male pearl gourami defending a nest may injure swordtails that stray too close, especially in a small tank.
Gear for a shared tank
Sized for the 30 gallon minimum this pairing needs. Affiliate links — we earn a small commission if you buy through them.
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
Corydoras catfish or plecos pair more safely with pearl gouramis and occupy completely different tank zones.
