  • Population biology / population structure / population dynamics : Daget & Ecoutin, 1976 | Durand, 1971 | Holden, 1963 .
  • Reproduction : reproduction takes place during high water on floodplains or smaller water bodies. courtship starts with a series of leaps from the surface by usually only one of the pair at a time, followed by a slow descent through the water; after a while the male stays very close to the female and at times the female will remain motionless in the water and the male will come up to her from behind and nudge her with sidewise movements of his head; the enlarged and swollen anal fin of the male is folded in a cup-like fashion and is used to brush the female. No nest is constructed, but the eggs are laid a few at a time throughout the thick vegetation .
