Rotifer culture

Hi all,
I know a bunch of you work with other fish. Have any of you cultured rotifers? My various projects have led me to thinking about culturing these. I have fed freeze dried rotifers to various fish and amphibians but haven't cultured them. Looking for any advice/sharing of experiences on culturing these.

Thanks,
al

I've not done rotifers, but have a couple paramecium cultures for CPD fry. I'm curious to see if anyone else has cultured rotifers as I've never really heard of many/any people doing so, but that probably means it's difficult. I've actually heard more about artificial rotifers than the real thing.
