If your breeding, and trying to raise fry, your success will be determined upon the hours you spend on the fry, many hours, many fry, simple.
Fry need live food, a pretty big job in itself, reideis need 3 initial foods, first you will need rotifers, live, ten copepods, live, these you have to culture, as in many tanks just for food, rotifers are not so hard, but they eat like monsters and will crash a algae culture in no time, so you will also need tanks of mico algae culture just to feed the rotifers. Copepods are easier, calanoids are what you will be wanting, lots.
After this, artimea, (bbs) these are easier as they come in a tin as resting cysts and you simply hydrate them, decapsulate and then hatch, rinse to rid the live from the remaining cysts, gut load and them feed out.
After al this you will need to then get some very small mysids, like hykari, and train them to eat frozen foods, which they do not easily take to.
If you can do this, and then also feed the fry 4-5 times a day, cleaning there tanks daily, weekly taking all out and sterilizing the tank, spending hours a day on them, you will have great success.
