In the wild, the barred danio is understood to be critically endangered, but is freely available from captive-bred stock. Typically, the fish prefer water with a 6.0-8.0 pH, a water hardness of 5.0-19.0 dGH, and an ideal temperature range of 69-79 °F (20-26 °C). Its diet consists of annelid worms, small crustaceans, and insects. The barred danio is oviparous (an egg layer), and is found
Danionin rerio", "D. nigrofasciatus", and "D. albolineatus"; the remaining "Danio" species were moved to "Devario", which at this time included "D. malabaricus", "D. kakhienensis", "D. devario", "D. chrysotaeniatus", "D. maetaengensis", "D. interruptus", and "D. apogon". The only "Danio" species to have been consistently called "Danio" were "D. dangila" and "D. feegradei". As "D. dangila" was the first discovered "Danio" (or type) the name "Danio" had to remain with "D. dangila", which is why the vast majority of species were moved to "Devario". Also, the sister group to "Devario" was deemed to be a clade formed by "Inlecypris" and "Chela", and more
