Dwarf and other relatively peaceful gouramis can often live with calm tetra species in a suitably sized planted aquarium. Keep the tetras in a proper school, avoid known fin-nippers around long-finned gouramis and make sure the gourami is not large enough to view the tetras as prey. Water temperature, hardness and adult size should be checked for the exact species involved.
'Gourami plus tetra' covers dozens of possible pairings. A peaceful dwarf gourami with a calm tetra school is very different from combining a large aggressive gourami with tiny fish.
Start with exact species
Compare adult size, temperament and water requirements for the exact gourami and tetra, not just the broad families.
Tetra school size matters
The RSPCA identifies tetras as shoaling fish and recommends six or more for shoaling tropical species. Under-grouped tetras can become stressed and behave less predictably.
Avoid nippy tetra species
Long gourami feelers and fins can attract repeated nipping from more boisterous tetra species.
Give the gourami cover
Tall plants and floating cover can create a secure upper-water territory while leaving open mid-water for the tetra school.

Frequently asked questions
Can dwarf gouramis live with neon tetras?
Often yes if temperature, hardness and tank size suit both.
Can gouramis eat tetras?
Large gourami species can prey on fish small enough to swallow.
Do tetras still need a group?
Yes. The presence of a gourami does not replace their own social school.
