food for fish fry??

Live food is best, fish grow fastest on live food. If the species of fry you have are a neutral pH fish then infusoria is best (it's difficult/impossible to culture infusoria in acidic water). Most of the literature states that infusoria is microscopic and not visible to the naked eye. That's not true. In a stagnant (no filtration/aeration) heavily planted tank exposed to daylight with no fish in there and at a temp of ~80F your naked eye will see living moving swimming & crawling organisms of all sorts after only 10 days. And if your timing is good you can leave it outdoors in the warmer months and you'll get mosquito larvae as well, which when only a few days old are small enough for fry. Once your fry are large enough to eat other fry you can breed one adult well-conditioned pair of Macropodus opercularis under the right conditions every week, and with coordinated timing scoop out the bubble nest with a large spoon while M. opercularis fry are hanging from the nest and feed it to your fry.
 
Drs Foster & Smith have Brine Shrimp Eggs, there are 2 types, one is supposed to be 80% hatch and the other 90% hatch rate. Last batch of the 90% I bought actually hatched around 50% so probably either old stock or they got fried by US Mail, if you order from them hopefully you'll have better luck.

I also just started using frozen Daphnia (from petsmart) and my fry seem to like most of it (has some brine shrimp in there that are a bit too big).
 
Hikari makes frozen baby brine shrimp, that's what I use for the first 2 weeks and then switch over to crushed NLS flake and then .5mm NLS pellets.
