خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 0; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 65 - 93. Diagnosis: adipose fin always absent; inner side of pectoral spine without serrations (Ref. 43912).
Schooling species, confined to larger rivers; most active during the night (Ref. 43912). Feed mainly on aquatic and small terrestrial insects (Ref. 6868), insect larvae and small worms (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Maximum reported TL 100 mm (Ref. 43912). Of very little economic importance; occasionally this species has been exported for aquarist purposes (Ref. 43912).
