Setting up a giant gourami community tank
Give the group a stable, planted 750 L+ tank with a gentle filter, a reliable heater and plenty of cover — broken sight lines and hiding spots let mid-water and bottom dwellers keep out of each other's way. Cycle it fully and stock gradually.

How to choose the right tank mates for a giant gourami
Being semi-aggressive, giant gourami can nip or harass smaller, slower or long-finned fish — give it space, broken sight-lines and similarly robust companions. It mostly occupies the middle of the tank, so it pairs naturally with species that use the other levels.
Giant Gourami grows to about 70 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 35 cm. Match its water, too: aim for 22–28 °C (72–82 °F), pH 6.5–8 and 5–20 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.
Giant Gourami doesn't need its own kind to feel secure; think twice before keeping more than one if it is territorial. Whatever you add, introduce new fish slowly, watch for bullying in the first days, and have a backup plan if temperaments clash.
