The zebrafish (Danio rerio) is a species of danionin belonging to the genus Danio in the suborder Cyprinoidei. Native to South Asia, it is a popular, hardy aquarium fish, frequently sold under the trade name zebra danio (thus often mislabeled as a "tropical fish", even though they also inhabit subtropical and temperate waters).
