The Giant Gourami, also known as Banded Gourami, Rainbow Gourami, or Striped Gourami, is a pale to golden yellow with silvery pale blue stripes running vertically along its body. In some parts of India it is used as a food fish, where it is dried and then eaten.
The Giant Gourami requires a tank that is 30 gallons or larger with densely planted edges, with preferably a dark tank bottom. There should be plenty of room left in the center of the tank for this gourami to swim. They prefer the company of other fish that are similar in size and temperament.
The Giant Gourami is an egg layer and the male will build a bubblenest before spawning. The male and female are distinguished by the dorsal fins and body color. The dorsal fin on the male ends in a point and the body is darker, changing to nearly black during spawning. When breeding, the water in the tank should be decreased to about 8 inches deep and the temperature should be 82°F. After spawning, the female should be removed to a separate tank because the male will jealously guard the eggs, sometimes becoming aggressive towards the female. The eggs will hatch in 24 hours.
The Giant Gourami is omnivorous and prefers algae-based foods as well as meaty foods. An algae-based flake food, along with freeze-dried bloodworms, tubifex, and brine shrimp will provide these fish with the proper nutrition.
