Family:  Danionidae (), subfamily: Danioninae
Max. size:  15 cm TL (male/unsexed)
Environment:  benthopelagic; freshwater
Distribution:  Asia: India, Bangladesh, Nepal and Myanmar (Ref. 4832). Reported from Bhutan (Ref. 40882).
Diagnosis:  Dorsal soft rays (total): 11-12; Anal soft rays: 15-19; Vertebrae: 34-38. Danio dangila can be distinguished from all congeners except D. assamila, D. catenatus, D. concatenatus, and D. sysphigmatus by produced first ray in pectoral and pelvic fins, large cleithral spot, and pattern of dark rings enclosing light interspaces on the side. It differs from those species by having vertically extended cleithral spot (vs. round in all other species), absence of complete anterior interstripe Ia (vs. present in D. assamila and D. concatenatus), round rings in series along side, width of dark perimeter of about same width as diameter of light centre (vs. elongate in D. assamila and D. sysphigmatus, with narrower perimeter in D. sysphigmatus), ring pattern usually extending onto caudal peduncle (present on part of caudal peduncle in D. catenatus and D. concatenatus, absent in D. assamila and D. sysphigmatus), and 32-34 lateral line scales (vs. 35-38 in D. sysphigmatus) (Ref. 101154).
