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
Danio margaritatus with a markedly blunt snout, measuring just 2–2.5 cm standard length. The body is about three times as long as it is high.
