Description: Recommended for an aquarium only when young. Young fish has 8-10 complete dark vertical bars on the reddish brown to dull orange body and also have a pointed head, while older individuals have a small, blunt head with a pronounced lower jaw. Juveniles can be easily confused with the Chocolate Gourami since the markings are similar, but this marking fades as the fish grow. Adults have a dark brown back and brown flanks covered with iridescent silver scales and their fins are also brown. A golden and albino variety also exists in aquaria. Has been introduced to several countries for aquaculture purposes, because Giant Gourami is a prized food-fish in its native countries. Giant Gourami is capable of breathing atmospheric air, so can survive under poor water conditions or in oxygen-depleted waters for long. The dorsal and anal fins are pointed on male, also with age he develops a hump on the forehead.

Because of their size, breeding in an aquarium is difficult though possible. Many fish are ready to reproduce at 6 months. The fish builds a ball-shaped nest of bits of plants, just below the surface. The spawning takes palce near the nest and large eggs are guided into the nest by the male. The female should be removed after spawning. The eggs are hatch in 24-36 hours and the fry become free swimming 3-5 days later. The fry are guarded until they are ready to leave the nest, ususally in about 2-3 weeks. The young can be fed with powdered flake foods or brine shrimp nauplii. They can grow rapidly given sufficient diet and space to move.
