Zebra Danio will eat a large variety of foods. Flake food for tropical fish
is a good staple for them. They will also eat fish eggs and young fry they
can find.
Danio breed rather heavily and a lot of energy is spent in this process.
For this reason any food you give them should be high in protein.
Brine
shrimp is a prized food for all fish since it is high in proteins and
other nutrients.
Feedings should be small and often. 4 or 5 small feedings are better then 1
or 2 large feedings. Feeding them as much as they will eat in a minute or
two several times a day will keep them healthy and strong.
