Danio er ættkvísl smárra ferskvatnsfiska í ættinni Cyprinidae frá suður og Suðaustur Asíu, gjarnan hafðir í fiskabúrum.[1] Þeir eru gjarnan með mynstur af láréttum röndum, röum af blettum eða lóðréttum röndum.[1] Sumar tegundirnar eru með tvo skegglíka skynþræði í munnvikum svipað og hjá styrjum. Tegundir af þessari ættkvísl éta smá skordýr, krabbadýr og orma.

Nafnið "danio" kemur úr Bengalska orðinu dhani, sem þýðir "af hrísakrinum". Danio var lýst snemma á 19du öld af Francis Hamilton. Tvær af tegundunum sem var lýst af honum í ættkvíslinni, eru enn gildar; D. dangila og D. rerio. Um öld síðar (1916) og með mörgum öðrum tegundum lýst í millitíðinni, var ættkvíslinni skift; stærri tegundirnar töldust til Danio og smærri tegundirnar til ættkvíslarinnar Brachydanio.[2] En 1991 voru ættvíslirnar lagðar saman aftur; margar stærri tegundirnar sem voru í ættkvíslinni Danio hafa verið endurflokkaðar í ættkvíslina Devario. Einnig, Brachydanio er nú samnefni af Danio.[3]

Það eru nú 27 viðurkenndar tegundir í ættkvíslinni:[1]
