you'll need a separate cycled tank with sponge filter, and air bubble circulation, and most importantly, the fry will need live rotifers of several sizes. If you don't have the set up already, I would not bother trying to raise this brood- but read up and try to raise the next one if you are interested. Good sign that they laid eggs in your tank though- congrats!
There is a short 30-page book, "Clownfish and Sea Anemones" by Tullock that has a brief discussion of a rearing setup, or "Clownfishes" by Wilkerson has more detailed description of how to raise clowns...
