Wow, yeah I would seperate anything small enough to fit into anything else's mouth. At 1cm I guess they should be able to tack quite large food compared to most fry. Maybe try some finely diced frozen blood worms.
Remember to do a small water change about 15 minutes after feeding to vacuum uneaten food and keep nitrates and ammonia down. If you can age a large container of water to use, so the water is the same every time you change water out, it would be beneficial.

aah ok, I would stick to BBS as the largest food for now. DO NOT OVERFEED.
BBS creates a lot of biological waste, even when alive.

I'm running an experiment, doing some of the fry I have a harder time in large tubs outside. Of course, you would need to wait for spring to do the same. It is realy low in time overheads, I feed them when I remember, but they grow regardless.
The little ones seem to be growing really fast, but its still a few weeks before I'd be able to see if I finally broke my long stint of deformed danio.
I started the tubs using aged water from a tub I left to stand under cover over winter. Full of bloodworms, daphnia and mosquito larvae. I also have lots of peppered cory juveniles in there to keep the floor cleanish and get rid of anything that can catch fish before it gets big enough. They would be fine with those fry.

lol I sound like October in the Winelands We can easily have a 30 degree C swing from morning till afternoon.
Today it actually rained, but it stayed so hot the water just evaporated after a few minutes. Luckily water is quite a good sink for heat, a large tub holds the temperature quite well if it gets warm enough in the day. Despite being overcast my tubs were at 21C at 9am this morning. But I've seen it drop to 14 one morning, so not warm enough for the angelfish to go outdoors yet.
