Danio is a small freshwater fish in the family Cyprinidae, currently found in South and Southeast Asia.  The fish lives in small ponds created by seeping groundwater or overflow from small brooks or springs.

The name “danio” comes from the Bangla name dhani, meaning “of the rice field”.

Danios are a hardy, lively species of fish that do well in cooler water, making them suitable for unheated tanks as long as the room is fairly warm. Most danios do well in community tanks, meaning you can keep them with a variety of other similar-sized fish. They are a great choice for any aquarium.
