Best gourami for freshwater tanks

10 species in this category on Fishori. Open a profile for tank size, temperament, then run pair checks before mixing.

Gouramis breathe air at the surface through a labyrinth organ. They want a warm, draught-free air gap above the water, with the cover glass close enough to keep heat in but not pressed onto the surface. Many species mix peacefully with the rest of a community, but two males of the same species rarely tolerate each other in anything under 200L. One male of any gourami species per tank is the safe default.
