Distribution and habitat

The blue danio is found on the islands of Langkawi and Ko Yao Yai in Malaysia.^{[citation needed]}

Description

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.

In the aquarium

The blue danio is a peaceful, active schooling fish, so is usually kept in groups. They prefer a well-planted environment, but still need plenty of space to school. Blue danios are often kept in 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).

Mating

Blue danios are egg-scatterers that spawn over coarse gravel beds. They will typically spawn at the first light of day.^{[citation needed]} The eggs will hatch in about 36 hours.

Etymology

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