Awesome this is a first for me

So if I want to help her keep the fry so they will survive I have a few questions then-
Should I set up a separete tank to put her in? And if so should I move her into it soon?
How long will she hold till she releases the fry?
Once the fry are released do I leave her with them in the fry tank for a bit or will she eat them if I leave her with them?
Anything else I need to know/should do?
