Occurs in small freshwater temporary pools in floodplains of streams and lagoons. These pools are shallow with compact, soft reddish brown muddy bottom and dry twice a year, during winter, usually from July to August, and during summer, usually from February to March. During dry season, all fish die and eggs undergo in diapause within the substrate. Eclosion happens at the onset of wet season, usually March-April and September-October (Ref. 42934). This species was introduced in California (Ref. 4357). Bottom spawner, 4 months incubation. Is easy to maintain in the aquarium (Ref. 27139).

Life cycle and mating behavior بلوغ | تولید مثل | تخم ریزی | تخم ها | Fecundity | توزاد ( لارو)

Males are territorial and very aggressive. Males display an elaborate courtship behavior beginning with waving lateral movement in front of female, with the unpaired fins completely opened. In an oblique position, the male touches the bottom surface with the anterior portion of its head, with vibrating body. The female placed her body side to side with the male. Then both couple dives into the substrates where spawning takes place (Ref. 42934).
