Ok, try to calm down, you sound really frazzled and that's not what fishkeeping should be about.
We all know that the majority of chain store employees don't have a clue about fish, sadly, so don't go there for advice.
I've never worried about my filter with my fry. In fact, I've had my krib fry sit on the filter intake to eat micro organisms and then they swim away. These are days old fry.
You can worry if you want to, but honestly, there's no need to.
Since you're not prepared, physically or emotionally, to do a whole "grow out fry tank" thing, keeping in mind that even if you just purchased a new fry tank it has to be cycled before you can stick fish in it, why don't you just leave her alone right now and whatever happens, happens.
Did you know when you purchased this species that they give birth constantly?
