Danio Bolognini

''Danio'' is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms.

Taxonomy

The name ''"danio"'' comes from the Bangla name ''dhani'', meaning "of the rice field". ''Danio'' was described in the early 19th century by Francis Hamilton. Two of the species included by him in the genus, still remain valid—''D. dangila'' and ''D. rerio''. 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 into the genus ''Brachydanio''.Spence, R., Gerlach, G., Lawrence, C. & Smith, C.
