Sherry if you haven't already you really got to check out MOFB.
I think some people have had some success with larvae food other than wild caught plankton such as SS rotifers (only the strongest larvae will be able to accept that as food) as well as A Tonsa freshly hatched nauplii (you'd have to culture them. I don't know where you'd get just eggs here in the US).
I am waiting for mine to start spawning as well and am thinking SS rotifers would be the most economical way to try it even if it means that only a few would make it through the critical stage on that.
