Blue Danio

The Blue Danio (Danio kerri), also known as Kerr’s Danio, is a tropical fish that originates from South-east Asia on the islands of
Langkawi and Ko Yao Yai in the Malaysian Peninsula. It is sometimes found in freshwater aquariums of hobbyists. The taxonomic name honors A.F.G. Kerr, who collected the first specimen on Ko Yao Yai in 1929.

The Blue Danio is blue colored with several pink/gold lines from the tail to the gills which may or may not be continuous, over a powdery blue side. It is a peaceful, active schooling fish. 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.

For hobbyists, this fish is usually kept in groups. They prefer a well planted environment but need plenty of room to school. Water temperature should be between 73 and 77 degrees Fahrenheit (23-25 C). Water hardness of 8 – 12 dGH and 6.5 – 7.0 pH is typical.
