Osphronemus

Osphronemus is a genus of large gouramis, the only genus within the subfamily Osphroneminae. These fish are known as the giant gouramis and are native to rivers, lakes, pools, swamps and floodplains in Southeast Asia, with O. exodon from the Mekong basin, O. laticlavius and O. septemfasciatus from Borneo, while O. goramy is relatively widespread. O. goramy has been introduced outside its native range in Asia, Africa and Australia.

All the species are highly prized as food fish, leading to farming of O. goramy and rearing of O. septemfasciatus. Osphronemus appear in the aquarium trade, but they are very long-lived, possibly reaching up to 40 years old, and require a very large tank with a strong filter.
