Adults inhabit freshwater rivers and lagoons, as well as brackish estuaries and coastal marine waters. Can tolerate temperatures from 11°C to 38°C. Large groups of juveniles are often encountered (Ref. 44894). Feed on arthropods, insects, aquatic plants, mollusks, prawns, crayfish, fishes and bottom detritus. Nest is constructed among gravel where eggs are deposited forming a mound (Ref. 205). The only species among oral incubating ariids exhibiting no parental care (Ref. 205). Breeding takes place from September to February (Ref. 44894). Marine populations of A. graeffei appear to undertake extensive anadromous migrations associated with breeding, but no such movements were observed in the fluviatile population studied (Ref. 38559).
發現於沿岸海洋了。 吃節肢動物，昆蟲，水生植物，軟體動物，蝦，小龍蝦，魚與底部碎屑。 A. graeffei 的海洋族群似乎進行伴隨著繁殖的廣泛溯河洄游產卵的迴游，但是沒有如此的運動在被研究的生活在河中的族群被觀察。 (參考文獻 38559)
