Tank Setup
Planted, slow flowing water, with open areas for swimming
Tank Region
Difficult. Bubble-nester. Remove the pair to it’s own tank, which should be densely planted and has floating plants. Lower the water level to 6-8 inches and and slowly raise the temperature to 85F. Feed the pair with lots of live food. The male, when ready, will construct a loose bubble-nest. The pair will be in a spawning embrace up to 2 hours, laying up to 2000 eggs. The female should be removed at this point.The fry hatch in 1-2 days, and the fry will be free-swimming two days later. At this point the male should also be removed. The fry must be fed small foods like infusoria 3-4 times a day for the first two weeks, and then they can take brine shrimp and powdered flakes. The fry are very sensitive to water quality, and you shouldn’t change the water until the fry are a half inch.
Good tankmates are trichogaster, botia, corydoras, barbs, angelfish, and loricariids. As with other gouramis, males will be territorial towards each other.

Not the most colorful gourami. The ventral fins are longer than most gourami species.
Males have red orange pelvic fins, and the females are yellow.
