You want one quarter of an inch of gravel on the bottom of your tank, with the heater adjusted between 70 and 80 degrees Fahrenheit. The longer you keep your fish, you can slowly adjust the temperature to a point to where you do not even need a heater.

When buying food for your new fish, it is recommended you use freeze dried worms and brine shrimp. Danios are a community fish and prefer to live in groups of a minimum of 6 fish.

These beautifully long, sleek and shiny fish are a wonderful addition to your aquarium. Danios originate in fresh water rivers and streams of Southeast Asia. These fish are becoming more widely known as new species have been found in Myanmar. They can grow between 4 cm to 15 cm, and are not expected to live more than a few years at most.

The Danio are wonderful fish to have with other types of fish. They can be unruly and have a tendency to chase one another and your other fish. This tends to lead to nipping of fins, although most of the time it was an accident. They will eat any fish small enough to fit in their mouths.

When preparing your water, you need to make sure the pH balance is between 6.0 to 8.0, and the water hardness of 5.0 to 19.0, with a temperature difference of 68 to 80 degree Fahrenheit, however cooler temperatures are preferable.

If you choose to breed your own Danios, you might want to arrange a smaller tank for the babies. Also remember that they like to scatter their eggs, which do not adhere to anything, and hatch within 2 to 3 days. Remember - their eggs make easy prey if there is not a heavy layer of marbles or Substrate plants.
