Danio was described in the early 19th century by Francis Hamilton, a surgeon working for the British East India Company.Two of the species included by him in the genus, still remain valid â Danio rerio and Danio dangila.About a century later (1916) and with many more species described in the meantime, the genus was split; the larger species into Danio and the smaller species, such as D. rerio, into the new Brachydanio.ost species of Danio have two pairs of long barbels, and they are generally characterised by a pattern of horizontal stripes, rows of spots, or vertical bars. Sizes range from about 25 to about 90 mm (1â3.4 in) in length.
