Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 15 - 18; Duri dubur: 0; Sirip dubur lunak: 19 - 24. Diagnosis: Body slender or moderate, its depth about 22-29% of standard length; 10-14 pre-pelvic and 7-10 post-pelvic scutes, no pre-pectoral scutes, first scute beginning slightly before or behind base of last pectoral fin ray and identical as following scutes without ascending arms; lower jaw strongly projecting, with strong canine teeth at symphysis; pre-maxilla with one large backward-pointing canine tooth on each side, about halfway along normal pre-maxillary series, rarely 1-2 smaller ones beside or a little behind it; lower gill rakers 18-29, shorter than corresponding gill filaments and the anterior ones reduced to stumps in large adults; anal fin with 19-24 rays; silver stripe along flank (Ref. 188, 54749). It resembles Pellonula vorax, which lacks canine teeth in the upper jaw and has one or more pre-pectoral scutes (Ref. 188).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Found in rivers and streams (Ref. 188), also lakes (Ref. 41580). A small predator, feeding on shrimps, mayfly nymphs and little fish (Ref. 41580, 54749).
