Can Dwarf Gourami Live With Rummy Nose Tetra?
Maybe, with caveats. Dwarf gouramis and rummy nose tetras share water parameters, but gouramis can be territorial toward bottom and mid-tank swimmers.
Why
- Dwarf gouramis reach 3.5 inches and tend to claim territory near the surface.
- Rummy nose tetras grow to 2 inches and school in the mid-tank region.
- Temperature overlap of 75-82F suits both species well.
- pH overlap of 6-7 works for both without compromise.
- Dwarf gouramis are known for carrying iridovirus, which spreads in stressed tanks.
What could go wrong
Dwarf gouramis may nip at rummy nose tetras if the tank is too small or if the gourami is particularly aggressive.

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 rasboras or corydoras; rummy nose tetras pair well with other small schooling fish or peaceful bottom dwellers.
