Danio is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia , commonly kept in aquaria .[ 1] They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars.[ 1] Some species have two pairs of long barbels . Species of this genus consume various small aquatic insects , crustaceans and worms .
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 .[ 2] In 1991, though, the two genera were recombined; most larger species formerly within the genus Danio have now been reclassified into the genus Devario . Also, Brachydanio is now a junior synonym of Danio .[ 3]
There are currently 27 recognized species in this genus:[ 1]
