Distinguished from all congeners of Danio by its color pattern comprising 6-7 brown vertical bars anteriorly on side and two horizontal rows of small brown spots posteriorly, absence of D stripe, and absence of dark stripes on caudal fin. This species is similar to Danio kerri and Danio erythromicron in having 12 circumpeduncular scale rows (vs. 14 in Danio dangila and 10 in other species of Danio); and in having 6 branched dorsal fin rays (vs. 7-8 in other species of Danio) (Ref. 81818).

Description: Dorsal fin ii.6½ ; anal fin iii.10½, iii.11½, iii.12½; pectoral fin i.10, i.11; and pelvic fin i.7. Lateral scale rows between dorsal and pelvic fins 7. (Ref. 81818)..
