背棘 (總數) : 0; 背的軟條 (總數) : 13 - 19; 臀棘: 0; 臀鰭軟條: 18 - 24; 脊椎骨: 29 - 31. Having series of small bluish white spots, often coalesced to form continuous or fragmented line, on subdistal area of caudal fin and dark brown to black stripe on border of anal fin, adjacent and parallel to perpendicular extensions of subdistal golden transverse lines. Dorsal head profile slightly convex to nearly straight in male, gently concave to approximately straight in female (Ref. 42934).

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).
在溪流與潟湖的洪泛區中出現於小的淡水暫時的水池。 這些水池感到水淺緊密的, 軟的紅褐色的泥底部而且一年兩次乾掉, 在冬天期間, 通常從七月到八月, 與夏天時, 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) 這種在加州被引入。 (參考文獻 4357) 底部產卵魚， 4 個月孵育時間。 容易在水族館維持。 (參考文獻 27139)
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。
