Length at first maturity / الحجم / وزن / العمر
Maturity: Lm 9.0, range 9 - ? cm
Max length : 21.0 cm SL ذكر/ مختلط الجنس; (Ref. 4833)
الأشواك الظهرية (المجموع) : 1; الأشعة الظهرية الناعمة (المجموع) : 6 - 7; شوكة شرجية: 0; أشعه شرجية لينه: 12 - 13; فقرات: 31 - 37. Body elongate and slightly compressed. Maxillary barbels extending beyond the pelvic fins, often to the end of the anal fin. Dorsal spine weak, finely serrated on its inner edge. Adipose fin small, inserted much behind rayed dorsal fin but anterior to the anal fin. Color in life varies with age; generally delicate gray-silvery to shining golden, with several (about 5) pale blue or dark brown to deep black longitudinal on side. A narrow dusky spot often present on the shoulder. The fins glass, with dark tips (Ref. 4792).
Facultative air-breathing (Ref. 126274); Adults inhabit standing and flowing waters. Usually found among marginal vegetation in lakes and swamps with a mud substrate. Feed on plants, shrimps, insects, mollusks and fish (Ref. 6028). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).
