ITS–The Gourami (Osphronemus goramy) is a freshwater tropical species which can be found from India to the Malay Peninsula and Indonesia. The species (reaching up to 60 cm long) has an oval-shaped, strongly compressed body with a small head and a thick protruding lower jaw. The body is brown in colour with a dark back and lighter belly.
During the juvenile stage, the gourami is slimmer and has a more pointed head than the adult. The female gourami has rounder anal and dorsal fins. The species is a bubble-nest builder, and the male gourami guards the young.
Before the invention of modern, synthetic fish food, the gourami used to be cultivated in ponds and fed with a local vegetable called sente (a type of cassava plant). The species prefers quiet, clean waters with plenty of vegetation, but also slimy ponds and mudholes. It breathes atmospheric air using a respiratory organ called a labyrinth.
In an aquarium, the gourami is very peaceful; thus the species is suitable for community tanks. Species from Indonesia are often exported to India, Thailand, the Philippines and China.
