The cyprinid fish genus Danio Hamilton includes 14 small species in South and Southeast Asia (Kullander et
al. 2009), as a rule diagnosable by distinct species-specific colour patterns. About half of the species of Danio
have a pigment pattern that consists of one or more dark or light horizontal stripes (Fang, 1998). Among the
others, Danio kyathit Fang differs in having the stripes broken up into rows of small brown spots, D.
margaritatus (Roberts) has a pattern of small light spots on the sides, D. dangila (Hamilton) has rows of dark
rings with light centres, and D. choprae Hora and D. erythromicron (Annandale) possess a distinct pattern of
vertical bars
