Danios - a Great Freshwater Tropical Fish
Danios are a great beginner’s fish for new aquarium owners, as
they are considered hardy and will get along well with most
other types of fish in your fish tank. The main consideration
to keep in mind if purchasing Danios for your tank is to buy
them in groups of six. They tend to need each other’s company
to survive, but you can choose from any of the varieties of
You should keep your aquarium heated to about 70 to 82 degrees
Fahrenheit for optimal temperatures for Danios, although you
can train these fish over time to live comfortably in an
unheated tank of water.
Danios could survive on floating flake food alone, but it is
beneficial to feed them occasional freeze dried bloodworms
(which are mosquito larvae) and Black Worms from time to time.
Some of the best friends for Danios in aquariums include
Rainbow fish, a single Red Tail Shark or a single Rainbow
Shark, all types of Barbs or most Gouramis (just try to pick
Gouramis that are smaller than Danios to avoid conflicts), or
schools of Clown Loaches,
Bala Sharks and Yoyo Loaches. At
times, livebearers like Mollies, Swordtails and Platies are
kept in aquariums among Danios, as well as Plecostomus Catfish
and Corydoras Catfish.
Danios are unique in that they can be used as the tank
“peacemakers”. Some types of Danios will distract aggressive
fish from fighting with the weaker fish. Female Betta fish are
known for attacking one another if kept in the same tank, but
add a school of Danios, and the Bettas will be distracted and
mind their own business!
Danio fish species live for a few years, with sizes ranging
from a small 1.5” of the Zebra, Gold, Leopard, and Pearl Danio
varieties to a large 5” in length of the Giant Danio variety.
