Found in small freshwater temporary pools, 10-40 m of diameter, about 50 cm deep, in floodplains of streams and lagoons or along the vast floodplains of lower rio São João, which are sometimes close to the sea (about 100 m). Substrate of compact, soft reddish brown mud; water hyaline, yellow or dark orange brown, usually not turbid. These pools are dry twice a year, once during winter, usually from July to August, and again 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).
發現於小的淡水暫時的水池了,10- 直徑的 40 公尺 , 大約 50 公分深, 在溪流的洪泛區與潟湖中或者沿著低 rio Sao Joao 的大量洪泛區, 有時那是接近海洋 (大約 100 公尺). 底部緊密的, 軟的紅褐色的泥; 水透明的﹐黃色的或深色的橘色褐色, 通常不是混濁。 這些水池一年兩次是乾的,一旦冬天的時候, 通常從七月到八月, 與再一次夏天時, 通常從二月到三月。 在乾季的時候，所有的魚死，而且卵在底部裡面的 diapause 中歷經。 Eclosion 在濕季的開始發生, 通常三月到四月與九月-十月.(參考文獻 42934)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
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).南美洲: 巴西。
