The Blue Danio or Kerr's Danio (Danio kerri) is a tropical fish belonging to the Danio family (Cyprinidae).

Description

Originating from South-east Asia on the islands of Langkawi and Ko Yao Yai in the Malaysian Peninsula, this fish is sometimes found in the fish keeping hobby. It is a blue colored, deep bodied Danio with several pinkish/gold lines from tail to gills which may or may not be continuous, over a powder blue side.

The Blue Danio is a peaceful, active schooling fish that is usually kept in groups. They prefer a well planted environment but still need plenty of space to school. Blue Danios prefer water with a 6.5 - 7.0 pH, a water hardness of 8 - 12 dGH, and a temperature range of 73 - 77 F (23-25 C).

Blue Danios are egg-scatterers that spawn among a coarse gravel bed. They will typically spawn at the first light of day. The eggs will hatch in approximately 36 hours.

The taxonomic name honors A.F.G. Kerr, who collected the first specimen on Ko Yao Yai in 1929.
