The blue danio, Kerr's danio or turquoise danio (Danio kerri), is a tropical fish belonging to the genus Danio in family Danionidae.

Distribution and habitat

[edit | edit source]

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

Description

[edit | edit source]

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

[edit | edit source]

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

[edit | edit source]

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

[edit | edit source]

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