Ooo! there is also baby food for that small of fry... it's like pellets, but made for small fry - a step up from powdered food, personally. If you want them to live, that can work :) otherwise they'll forage on the bottom, on live plants, microorganisms like infusoria... etc... which I have done with some small fry breeds
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
