Life cycle and mating behavior
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
Spawns in shallow water with shelving bottom in ponds. Size of first spawning depends on population density (lower at higher densities). Mating pit is the size and shape of a saucer. Eggs probably fertilized before being taken into the mouth by the female, or are fertilized inside the mouth (Ref. 2).
