背面の脊椎 (合計) : 14 - 17; 背鰭 (合計) : 10 - 12; 肛門の骨: 3; 臀鰭: 6 - 8. Diagnosis: high number of branchiospines on first outer branchial arch (23-31); first dorsal fin spine length 70-80% of the length of the 5th spine (Ref. 59155, 52307, 81260). When stressed with 2 continuous dark bands on body (Ref. 81260).
Found in middle sized or large rivers; small specimens prefer shallow regions and are found as single specimens or in small groups of 2-4 individuals between sunken wood or stones near the bank, while adults swim in deeper regions in the middle of the rivers (Ref. 59155). Diet consists mostly of detritus, aufwuchs and other, preferably vegetative, components (Ref. 52307).
