Can Dwarf Gourami Live With Swordtail?
Maybe, with caveats. Dwarf gouramis are labyrinth fish that can be territorial, while swordtails are active livebearers. The two may clash in smaller tanks.
Why
- Dwarf gouramis reach 3.5 inches and establish territories in the middle and upper water column. Swordtails at 4-5 inches also occupy mid-level.
- Temperature overlap of 72-82°F and pH overlap of 7-7.5 work for both species.
- Dwarf gouramis are slow-moving labyrinth fish that may be outcompeted for food by faster swordtails.
- Male dwarf gouramis can be territorial toward each other and similar-looking fish. Swordtails are not similar in shape but may still trigger aggression.
- Dwarf gouramis are prone to iridovirus, which spreads in stressed populations. Adding active swordtails may increase stress on gouramis.
What could go wrong
A stressed dwarf gourami may lose color, hide constantly, and become vulnerable to disease outbreaks that can affect the whole tank.
Gear for a shared tank
Sized for the 20 gallon minimum this pairing needs. Affiliate links — we earn a small commission if you buy through them.
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
Sparkling gouramis or honey gouramis are smaller and less aggressive alternatives that pair more peacefully with swordtails.
