Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼

Male guards the floating bubble-nest where the eggs are laid, about 600 in number. Hatching takes place in 12 to 24 hours while the male parent continues to protect the nest. In about three days, the developing larvae become free-swimming and leave the nest. In an aquarium setting, it is about this same period that the male should be removed from the tank to lessen the probability of him eating the young (Ref. 1672).亞洲: 巴基斯坦，印度與孟加拉。 這是被在它的原產地的外邊被分佈的廣泛地那裡有的小 gouramis 的小而最受歡迎者。 (參考文獻 1739)
