簡短描述
檢索表 | 型態特徵 | 形態測量圖
臀鰭軟條: 16 - 19; 脊椎骨: 55 - 57. Eye size 12.9-21.8% HL. Because of its similarity to A. paucus, the remaining diagnosis refers to both A. midgleyi and A. paucus: a sleek body; strong jaws; jaws upturned slightly at symphyses, mouth broad; snout truncate in profile; head oblong, its width averaging 66% HL. Supraoccipital process narrow with parallel margins. Numerous fine, sharp teeth on palate in transverse band of four oblong groups. No rakers on posterior aspect of gill arches. Barbels thin and short, rarely reaching beyond pectoral fin base and less than 25% SL (Ref. 40908).
眼睛大小 12.9-21.8% HL。 由於它的類似 A. paucus, 剩餘的鑑別參考依據為 A. midgleyi 和 A. paucus: 一個光滑的身體; 強的顎; 顎朝上的些微地在癒合處, 嘴寬的; 吻截形的輪廓; 頭部長方形, 它的寬度平均 66% HL。 上枕骨突起狹窄的有平行的邊緣。 很多的細, 銳利的在四個長方形群的橫跨條紋中牙齒在上顎。 沒有耙鰓弓的在後部面。 觸鬚細又短的, 很少地超過胸鰭基底而且少於 25% SL.(參考文獻 40908)
Inhabits in lakes, billabongs, rivers and to a lesser extent brackish estuaries and the tidal portion of rivers. Found in clear or turbid fresh water reservoirs and waterholes. Water is typically warm (23-35°C), with pH between 7.0-8.7 (Ref. 44894). Feeds mainly on fishes, prawns and crayfish. Various arthropods are also consumed. Breeds early in the wet season, sometimes extending into the late wet (November to March). Eggs are incubated orally by the male for 5-6 weeks; brooding males form groups in deeper water. Juveniles grow quickly, attaining 20-30 centimeters by the end of the first year, and sexual maturity is reached after 3 years. An excellent eating fish, rapidly growing in popularity (Ref. 44894).
發現於湖，死水潭，河了與對一個較少的範圍半鹹淡水河口與河的潮汐部分。 主要吃魚，蝦與小龍蝦。

回復力 (Ref.
