Maturity: Lm ?  range ? - ? cm
Max length : 15.1 cm SL جنس نر / بدون خواص جنسي; (Ref. 81642)
خارهاي باله پشتي (کل): 2; شعاع نرم باله پشتي (کل): 7; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 7 - 8. Diagnosis: caudal peduncle short and broad, its depth more than 2 times the horizontal distance between anal and adipose fin bases, rarely even deeper; anterior edge of pectoral spine coarsely serrated, with numerous small serrations, more numerous than those along the posterior edge (Ref. 81642). Barbels generally short: maxillary barbel reaching a little beyond pectoral spine base, external mandibular barbel not reaching tip of spine (Ref. 81642) but up to level of dorsal-fin spine, and inner mandibular barbel up to beginning of opercula (Ref. 57126), but it should however be noted that some juvenile specimens have slightly longer barbels (Ref. 81642). Adipose fin not always high and solid; colour pattern usually with 5-7 vertical bands (Ref. 81642).
Nocturnal and crepuscular; preys on insect larvae, crustaceans, and small fishes (Ref. 6868). Maximum reported total length 24.5cm (Ref. 3236).
