ການຖ່າຍທອດທາງກຳມະພັນຈາກພໍ່ແມ່ຫາລູກ: 0; ຄີກົ້ນຂອງປາ: 30 - 37. Diagnosis: teeth small and conical (Ref. 4903, 81274), arranged in a single series confined to the middle of each jaw, 5-6 in both jaws (Ref. 4903). 16(-18) scales around caudal peduncle (Ref. 4903, 81274). Body depth 3.0-4.7 times in standard length; anal-fin base 0.7-0.9 times in dorsal-fin base (Ref. 81274). Head length 4-5.5 times in SL; upper head profile gently curved; snout 1/3-1/4 length of head; eye 1/2-2/3 length of snout; mouth small, a globular, fleshy swelling on the chin (Ref. 4903). Dorsal fin beginning slightly behind level of anal fin-origin (Ref. 2915, 81274), above the the 6th-9th anal fin ray (Ref. 4903) and comprising 25-31 rays (Ref. 2915, 4903, 81274). 70-92 lateral-line scales (Ref. 4903, 81274). Caudal-peduncle 2.0-3.4 times longer than deep (Ref. 2915, 4903, 81274). Caudal fin partly covered with small scales, its lobes pointed (Ref. 4903).
Coloration: silvery-grey, sometimes dark grey to blackish (Ref. 81274) or dark bluish-green dorsally (Ref. 4903).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Adults inhabit lakes, lagoons, reservoirs and (irrigation) canals. They are bottom feeding insectivores that breed during the flood season and enters the floodplain for this purpose (Ref. 28714). Thay show three 'preferred' modes of intervals between electric organ discharges (inter-EOD) when at rest: 10-35 ms, 50-120 ms and 200-350 ms (Ref. 10833).
