I have been culturing daphnia by using a liquid food, which I made up from
a recipe off the Live Foods mailing list. I use Gram flour (or chick pea
flour), and mix up a small spoon of this flour with some water. I then add
this liquid to the culture until the water turns slightly cloudy. When the
water in the culture clears in a few days, add a little bit more of this
liquid. I have been using this "food" with great success compared with
green water, and have found that a culture can multiply relatively quickly.
The other added benefit over green water is that I can see the daphnia to
pick out the smaller ones to feed my bow fry.
