Thanks very much Stefanie. I have Sanders premium brine shrimp, definitely very fine, but in this case you can clearly see they do not even try to hunt the napulii because they are to big for them during the first days. As I removed the parents from the first tank, the fry is quite easy to observe as they do not hide as much as when there are adults in the tank. You can see them to have their own microteritories that at least the strongest youngsters defend against others. As there is plenty of leaves and plants in there I think the biggest and strongest fry defend the places where the water flow brings most of the food. I did not try to isolate any fry without any smaller food yet, but I will definitely try it when I get Artemia franciscana or San Francisco Bay brine shrimp if you want. It would be great if they are able to ingest these, Infusoria are hard to handle well and you are always balancing on edge of either having food that is not valuable enough or having poluted water in the culture. For Rotifera its again a matter of value. Both are reproducing rapidly and have very low energy storing capacity so the fry will most likely grow much faster when or once it is able to ingest Artemia that has huge energetic reserves when freshly hatched.
