Differs from A. nasutus and A. orthodus by its distinct humeral blotch and intermediate body depth. Sides and belly silvery over pearl white merging to a greenish brown back; in preserved specimens, a gray band runs from the humeral mark to the caudal peduncle which has a jet black rhomboidal mark extending to the tip of the middle caudal rays; transparent fins with minimal dark pigment; usually first rays of anal and sometimes dorsal and caudal fins with red or yellow pigment (Ref. 36880).
用它的明顯肩部斑塊與中間的體高有別於 A. nasutus 與 A. orthodus 。 對一個綠褐色的背面側邊與腹面銀色的鉛白合併之上; 在保存的標本中，一條灰色的條紋從對有一個延伸至中央尾部的鰭條的頂端的墨黑色長菱形的標誌的尾梗的肱骨標誌; 透明鰭有最小的深色; 通常第一個鰭條肛門的與有時背鰭與尾鰭鰭有紅色或黃色的有顏色.(參考文獻 36880)
Inhabits all types of rivers and streams, from swift water to swamps and stagnant pools (Ref. 36880). Tolerates brackish water at sea level to small mountain brooks at 1000 m elevation (Ref. 36880). Forms schools over any type of substrate (Ref. 36880). Feeds on algae, seeds, leaves, aquatic and terrestrial insects and fish fry of any species (Ref. 36880). Spawns during most of the year at some sites or seasonally in other places (Ref. 36880).
從湍急的水域到沼澤與污濁的水池, 棲息於所有類型的河川與溪流。 (參考文獻 36880) 在海平面到小的在 1000 公尺海拔的山地溪流容忍半淡鹹水。 (參考文獻 36880) 在任何類型的底部之上形成魚群。 (參考文獻 36880) 吃藻類，種子，樹葉，水生與陸棲的昆蟲與任何種的魚苗。 (參考文獻 36880) 在一些位置產卵於全年大部分時間或季節性地在其他的地方中.(參考文獻 36880)
