The giant gourami (Osphronemus goramy) is a large freshwater fish native to Southeast Asia. It is known for its ability to breathe moist air, which allows it to survive out of water for extended periods. Reaching lengths of up to 70 cm, it thrives in rivers, swamps, and lakes. It grows quickly and is valued both for its ease of farming and as a high-protein food fish with firm, boneless flesh.
