Comments: Widespread across northern and western Taiwan (including Ilan, Taipei, Taoyuan, Shinchu, Miaoli, Taichung, Chanhwa, Yunlin, Charyi, and Tainan Counties), except river basins south of the Tzengwen River. Artificially introduced in eastern Taiwan (Hualien and Taitung Counties) which has subsequently expanded its range in these basins and caused greatly substantial declines of the locally endemic cyprinid (Aphyocypris kikuchii) and gobiid fishes (two species of Rhinogobius spp.) (Ref. 81910). Also Ref. 5193, 33508, 47271.

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Mating behavior: Usually begins with fighting among males. Only one mates. Females rest on sandy ground and the male presses her belly. This makes the female tilt with her anus closer to the male. The male vibrates and releases the sperm. Subordinate males often join the spawning pair, perhaps to release their sperm.
