Male pursues a slow-moving female and upon catching up with the female, will begin shuddering from side to side while the pair is oriented parallel to each other; the pair positions themselves close to submerged vegetation; male assumes a slight head-down position , with his anal fin curled under the female's vent; the pair begins trembling until a single large egg is released; each female produces about a dozen eggs per day; eggs hatch in about a week; no parental care (Ref. 44091).亞洲: 斯里蘭卡與印度向東至湄公河。
