How to feed 'baby' anemones

I have a bubble tipped anemone that has split twice. From what I have
read sometimes after they split both are the side of an 'adult
anemone' but each time it has sseparated I find what I call a baby
anemon that is very small (about a 1/4 inch diameter). It's like just
a very small piece breaks off but both times I saw it for a few weeks
and never again. My concern is they are starving but yet how do you
feed one of these? I feed silversides to my regular anemone but know
I can't to these and is there something smaller to feed or is that not
the problem I'm having?
