The circumstances:
I have a young Marisa Cornuarietis. I also have a batch of angelfish fry at about a week old. The kicker is that I also have to drive my mom to Idaho to see my sister this weekend. I won't be able to feed them for about three days!
The tank and methods:
The fry tank is a lively ten gallon, with two species of nematode(one dot-sized, the other eyelash-sized), three or four adult fairy shrimp on cleanup and filamentous algae just sprouting since yesterday. 100watt fluorescent blasting 24/7. It's got an aquaclear 50 set to trickle baffled by a scotch-brite pad and a heater keeping the water at about 82ºF. I am feeding boiled egg yolk, pulverized high-quality dry food and squirts of water from my tubifex/snail/fairy shrimp tank. So far, they are doing ridiculously well. This is my first attempt and I've already got them to the free-swimming stage. There are about thirty or forty of them, and they are the first spawn of a young pair of angels from my community tank.
The potential solution:
Apple snails produce infusoria as a waste product, I've been told. As such, I've considered adding him during my absence as a life-support mechanism to feed them something while I'm gone. I assume they'll eat the algae, too, and perhaps the smaller nematodes if they get desperate. The snail would feed on fresh broccoli leaf. Has anyone used apple snails to feed fry before?
 
i dont know about all of that but maybe you could buy an auto feeder and use hikari first bites, or you could buy one of those toms hatch and feeders for brine shrimp. not sure about the later as i have no experience with the toms but those might be 2 options.
 
When I am away for a few days, I just leave heavy thickets of plants for my snails and fish to eat. Lots of microorganisms harbor the plants.;)
 
Out of random curiosity, would fry eat milt if a breeding pair of fish were in the same water system?
 
What a weird concept about fry eating milt. I've experienced them eating eggs but milt, no.
 
Any other fry and Id say dont worry theyll be fine.But angels are so delicate while young and need a constant food source.The plants and snails idea is good.Alot of plants.Got any sponge filters?a well used sponge filter is a great feeding station for fry.They should be able to tackle newly hatched brine shrimp,those are great nutritious food.Feed them that till you leave.
Adult dapnia would be too big for them to eat but would drop juveniles that the fry could eat while you are gone.

You mean they will eat the beneficial bacteria and other random critters? That's not a bad idea except that I'd worry about the waste produced by the potential die-off. I found some three-day feeder blocks that they are eating, and the hair algae is EXPLODING off of the walls like jungle vines. I will put the snail in there when I leave and maybe a small piece of cycled media (if that's what you meant).
 
OMG! I haven't been able to feed my fry for a whole 24 hrs! Their stomachs are always full! I guess I've succeeded in creating soup in there. The only concern now is stability and sustainability. I just added the Marisa snail (and his bio-media) along with a brand new broccoli leaf. I leave tomorrow night, which is when I'll add the dissolving food block, a small chip of which they've already devoured. *crosses fingers*
