Golden Gourami tank mates
Trichopodus trichopterus
5 rated pairings from the Golden Gourami care guide. Compatibility here means water, temperament, tank zone and adult size all line up — the note on each card says why. Golden Gourami needs at least 20 gallons on its own; every companion adds to that.
