背棘 (总数) : 0; 背的软条 (总数) : 13 - 19; 臀棘: 0; 臀鳍软条: 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).
有成列的小蓝白色的斑点, 时常合并形成连续或者碎片了线, 在臀鳍的边缘上的尾鳍与深褐色的到黑色的斑纹子末梢部区域上, 毗连的而且平行于子末梢部金的横切线的垂直延长。 头部背面轮廓些微中凸到几乎是直的在雄鱼中, 逐渐地凹曲到大约笔直地母鱼.(参考文献 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).
在溪流与泻湖的洪泛区中出现于小的淡水暂时的水池。 这些水池感到水浅紧密的, 软的红褐色的泥底部而且一年两次乾掉, 在冬天期间, 通常从七月到八月, 与夏天时, 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) 这种在加州被引入。 (参考文献 4357) 底部产卵鱼， 4 个月孵育时间。 容易在水族馆维持。 (参考文献 27139)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 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。
