I too usa a concoction of Sera micron, liquid fry, vinegar eels, and
crumbled egg yolk mixed with water. Feed this as many times during the day
as you can manage and if possible do a 10% or so water change every 2nd day.
(BTW I use a small airstone and no filtration whatsoever on my fry tanks....)
Use only the tiniest amount of exremely fine egg yolk. The larger particles
you can throw in with you other fishes, they just love the stuff.
As the fishes grow I get them onto Brine shrimp and Micro worms, eventually
giving them flake and live food when available.
The results of my feeding regime have been successful enough to maintain a
supply of stock sufficient enough for me and those who want some :)
