Tank compatibility[edit]

This is a peaceful fish and should be housed with other peaceful fish. Zebra Danios can be fin-nippers if not kept in proper shoal and should therefore be kept in groups of 5 or more. Their extremely active nature can also bother shy or slow moving fish such as Gouramis. They can be used as dither fish.


Will take flake and pellet food as well as live/frozen food such as bloodworm, brine shrimp and daphnia. Very easily fed.

Feeding regime[edit]

Feed once or twice a day.

Environment specifics[edit]

This fish enjoys planted tanks, however, it prefers room to swim over a heavily planted tank. This fish MUST have room to swim back and forth, therefore a long tank of at least 76 Litres (20 US G.) is preferred over a tall tank or hexagon.


Zebra Danios are very social, extremely active creatures. Primarily occupying the top levels of the tank, they do best in groups with room to swim and chase each other. If too few Zebra Danios are kept in an aquarium, they will harass other fish and may turn to fin nipping.


Blue and silver or gold horizontal stripes. Regular and long-finned varieties available. This is the species from which the GloFish was created. There is also another morph available known as the Leopard Danio.
