Krib Fry

[TarkMalbot]

I have about 30 Krib Fry knocking about the bottom of the tank.  They are being well guarded by Mum and Dad are currently grazing on the bog wood and gravel but what can I feed them without the other fish eating it first on its way down?  I fed some frozen daphnia this evening so am hoping some of that managed to sink to the bottom.
 
Someone mentioned Hikari First Bites but was wonder what others thought.
 
Thanks,
