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).
发现于小的淡水暂时的水池了,10- 直径的 40 公尺 , 大约 50 公分深, 在溪流的洪泛区与泻湖中或者沿着低 rio Sao Joao 的大量洪泛区, 有时那是接近海洋 (大约 100 公尺). 底部紧密的, 软的红褐色的泥; 水透明的，黄色的或深色的橘色褐色, 通常不是浑浊。 这些水池一年两次是乾的,一旦冬天的时候, 通常从七月到八月, 与再一次夏天时, 通常从二月到三月。 在乾季的时候，所有的鱼死，而且卵在底部里面的 diapause 中历经。 Eclosion 在湿季的开始发生, 通常三月到四月与九月-十月.(参考文献 42934)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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。
