Giant danio feed on mosquito larvae, chironomous larvae, white worms, chopped earth worms, or commercially available pet food. Giant danios are found in fast-flowing streams, usually in hilly areas. Giant danios prefer shaded and clear water. They also prefer gravel or sand sediment. Giant danios are shoaling fish, meaning they are found in social groups. Giant danio breeding can be induced in captivity. In captivity, breeding is induced by increasing water temperature and creating artificial rain. Juveniles begin to resemble their adult form after 65 days of development. Females are larger than males and also possess a more rounded abdomen. Males interested
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
