Deep body (body depth 11-13% TL versus 6-10) possessing very thin pale bands (less than 1/5 the width of the dark bands) with sharp (high contrast) margins. Bands are sinuous on the anterior half of the body, and extend clearly to the dorsal midline (Ref. 41292).

Parental care is provided by the male. Nests consisted of a group of small juveniles under a dense roots of floating macrophytes which are attended by a single male adult (Ref. 55570).南美洲: 在中央亞馬遜河 (在 Tefe 附近的 Mamiraua 湖系統 , 與在馬瑙斯附近的 Lago Janauaca) 的 Rio Solimoes 洪泛區上的二個白水的湖系統, Amazonas 說巴西.(參考文獻 41292)
