If you have a bloom of rotifers in the daphnia vat/bucket/whatever, so long
as it isn't too likely to have temperature swings between extremes, why not
carefully adjust a few fry to the container. They could enjoy the rotifers
and could then be removed? That isn't a solution all the time, but why waste
good live food?  ;)

All the best!
