Etymology: Danio: From ‘dhani’, local Bengali/Bangla name for small minnows (Ref. 2031); flagrans: The specific epithet flagrans is a Latin participial adjective meaning flaming, blazing, burning, glowing, and is given in reference to the red to orange color in living specimens, and with inspiration from the name glowlight danio applied on this species and Danio choprae .

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 7 - 11; Raggi anali molli: 13 - 15; Vertebre: 34 - 36. Distinguished from all congeners by the following combination of characters: rostral barbel present; mandibular barbel present; lateral line abbreviated, rarely absent; color pattern consisting of vertical bars or spots anteriorly on side, horizontal stripes posteriorly on side; branched dorsal-fin rays 7 1/2; circumpeduncular scale rows 10. Similar to Danio choprae but differs from this species by slightly more slender body (22.5-26.6 % SL vs. 26.6-31.6% SL), longer caudal peduncle (20.5-24.7 % SL vs. 16.1-19.1 % SL), shorter anal-fin base (14.2-18.3 % SL vs. 19.2- 23.9 % SL), longer rostral barbel (10.3-18.7 % SL vs. 5.9-10.1 % SL), reaching caudally beyond preopercular margin in adults (vs. not reaching posterior margin of orbit); longer maxillary barbel reaching to below pectoral-fin base in adults (vs. not reaching to pectoral-fin base), lateral line almost always present, on up to seven scales (vs. almost always absent, occasionally on up to three scales), more vertebrae contained in caudal peduncle (9-10 vs. 6-8), fewer anal-fin rays (9 1/2- 11 1/2 branched rays vs. 12 1/2-13 1/2, rarely 11 1/2), anal-fin base hyaline (vs. anal-fin base dark), and black streak absent from lower lobe of caudal fin (vs. usually present) (Ref. 93124).
Body shape (shape guide): elongated.
The type locality was a very small stream, about 50 cm wide, almost dry and with no other fish present. Also found in a small stream, about 2 m wide and less than 1 m deep, with fast flowing cold water, no aquatic vegetation, lots of boulders and wood in the stream, substrate composed of sand and gravel. Another collection site was a stream up to 4 m wide and 2 m deep, with clear cool water, faster flowing parts but also deeper pools with slower water and no aquatic vegetation (Ref. 93124).
