Zebrafish
The zebrafish (Danio rerio) is a freshwater fish native to India. It is often sold under the name zebra danio.
In the aquarium
The zebrafish is a peaceful fish and can be kept in a community tank.[1] They can be kept in a temperature of 19–27°C. They grow to about 5 cm.[2]
The typical environment of the Zebrafish is in rivers, little streams, slowly flowing pools close to nearby streams and rice paddies
The natural history of the Zebrafish is limited as very little information about their true natural history is known. However, it is known that Zebrafish have a high reproductivity and quick growth rates.
Additional Facts: Zebrafish are suitable models for researching tissue repair and regeneration in vertebrates because of their restorative capabilities. They can fully regenerate injured hearts, portions of their brain and other organs.
Zebrafish are one of the most common species used for genetic and developmental research.
Diet
Zebrafish happily eat flake foods and bloodworm.
Other foods Zebrafish consumes are mosquito larvae and zooplankton.

Zebrafish chromatophores, shown here mediating background adaptation, are widely studied by scientists.

FDA research used Zebrafish to show the effects of ketamine on neurological development.
