Also caught with drawnets. The habitat preferences are strongly influenced by the presence or absence of the tigerfish Hydrocynus forskahlii: if the tigerfish is absent, S. thumbergi is found in open waters and sometimes in fast-flowing rocky habitats; in areas where the tigerfish occurs, S. thumbergi is relegated to lagoons, backwaters and marshy shallow areas. Feeds on small fish, insects and snails (Ref. 6465).
也用拖網捕獲。 棲息地偏愛強烈地被影響藉由出現或者缺乏虎魚 Hydrocynus forskahlii: 如果虎魚不存在, S. thumbergi 被發現於開放的水域與有時在快速流動的岩石棲息地; 在虎魚出現的區域中， S. thumbergi 被撤離到潟湖，洄水區與多沼地的水淺區域。 吃小魚，昆蟲與蝸牛。 (參考文獻 6465)
