Etymology: Pseudobarbus: Greek, pseudes = false + Latin, barbus = barbel (Ref. 45335).
Eponymy: This is not an eponym but a toponym as, despite the spelling of the vernacular name, this species is named after the Burg River. (Ref. 128868), visit book page.

Africa: Occurs in the Berg River system and Verlorenvlei Rivers, southwest Cape. Probably extinct in the Eerste River, Cape Province, South Africa (Ref. 2801). Decline caused by habitat deterioration and impact of introduced predatory species (Ref. 3881). Western Black Sea basin: from Kamchiya (Bulgaria) to Düzdere drainages (Turkey) (Ref. 59043).
非洲: 出現於冰山河流域與 Verlorenvlei 河，西南的岬。 可能滅絕在 Eerste 河，南非的開普省中.(參考文獻 2801) 因為棲息地惡化與引入掠奪魚種的衝擊而減少。

Usually found near vegetation except when the water is turbid. It can tolerate extreme conditions and survive in various habitats from small streams to large impoundments. Feeding habits varied in different seasons: for small fish benthic feeding during spring and midwater feeding during summer; larger fish fed on corixid bugs during summer but switched to chironomid larvae and zooplankton in winter. Capable of jumping when ascending rapids (Ref. 6465).
除了水何时是浑浊的以外通常发现于植物附近。 它能在来自小的溪流到的各种不同的栖息地容忍极端环境而且存活大的圈围水域。 摄取食物的习惯在不同的季节中改变了: 因为小鱼春天时底栖性觅食而且夏天时在中层水域觅食; 较大的鱼以小昆虫为食了夏天时但是转变成宝刀鱼仔鱼与浮游动物冬天时。 当上溯急流，能够跳跃。 (参考文献 6465)
