kinds of food for fish fry?

[WA coral]

I now have a breeding pair of clowns and am in search of success stories and what was used to make it work, as in what kinds of foods were used and conditions. I have heard rotifers and such but will any thing else work? I saw a product called rotifeast and was wondering if any one else has used this before with fish fry ? any easy foods to keep besides rotifers? any info would help. thanks andy
