背棘 (总数) : 0; 背的软条 (总数) : 0; 臀鳍软条: 230 - 320. Distinguished from its congeners endemic to the Amazon and Orinoco basins and the Guyana Shield in having a color pattern of 14-20 oblique, dark, pigment bands with wavy and irregular margins in which the majority of bands are branched ventrally to form inverted Y-shaped patterns (in adults), in which the dark bands are about twice as broad as the pale interbands and in which the bands rarely form X-shaped patterns at midbody. Further differs in having the following unique combination of characters: clear (unpigmented) patch at the caudal end of the anal-fin membrane in specimens 6-23.5 cm; bands never divided to form band pairs (Ref. 55508).
在有一个方面与它的同类区分了亚马孙河的特有种与奥里诺科河流域与盖亚那盾甲 14-20 斜角的彩色斑纹, 深色的, 有颜色条纹用波浪状而不规则的边缘在那一个多数的条纹腹地被分枝形成反转 Y 形的图案 (当成鱼时), 在那里深色条纹是像灰白的 interbands 一样的宽大约两倍于与在那一个条纹很少地在身体中央形成 x-形状的图案。 进一步不同之处为有下列的独特组合特征: 在臀鳍薄膜的尾鳍末端在标本 6-23.5 公分的清澈的 (没有颜色) 小区块; 条纹从不分开形成条纹对。 (参考文献 55508)
Facultative air-breathing in the genus (Ref. 126274); Inhabits mainly isolated swamp pools in the rain forest, which it can reach by moving over-land through moist leaf litter (Ref. 55508). Also occurs in small swamp pools that are never connected to streams and that dry out completely during periods of draught (Ref. 55508). Undertakes aerial respiration by gulping atmospheric air into the hypervascularized posterior chamber of the gas bladder (Ref. 55508). Observed to survive out of water for many hours on a moist substrate (Ref. 55508). Feeds mainly on chironomid larvae, insect nymphs and allochthonous invertebrates that fall from the forest canopy (Ref. 55508).
主要栖息于在雨森林中隔离沼泽水池, 它能被移动达到-登陆过潮湿的腐叶.(参考文献 55508) 也生活于小的沼泽水池从不那是连接到溪流，而且那在气流的期间完全地干掉中.(参考文献 55508) 进行藉由吞大气的空气进入气鳔的 hypervascularized 后室呼吸空气.(参考文献 55508) 观察存活在一个潮湿的底部上离开水面许多小时.(参考文献 55508) 主要吃宝刀鱼仔鱼, 昆虫的蛹与从森林覆盖掉下的外来的无脊椎动物。 (参考文献 55508)
