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。 (參考文獻 3881) 西方黑海流域: 從 Kamchiya(保加利亞) 到 Duzdere 流域 (土耳其).(參考文獻 59043)

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).
除了水何時是混濁的以外通常發現於植物附近。 它能在來自小的溪流到的各種不同的棲息地容忍極端環境而且存活大的圈圍水域。 攝取食物的習慣在不同的季節中改變了: 因為小魚春天時底棲性覓食而且夏天時在中層水域覓食; 較大的魚以小昆蟲為食了夏天時但是轉變成寶刀魚仔魚與浮游動物冬天時。 當上溯急流，能夠跳躍。 (參考文獻 6465)
