I'm sorry it was a bit hard to understand at the very end. by saying you want to keep the females out of the fry do you mean you want adults and fry kept separetely, or do you not want the females to get pregnant again? ill assume you want them separate. Good way to do this is to set up a 6 gal or a bit smaller bookshelf (one of those plastic critter tanks) for a birthing tank. put a pregnant female in there about a week or two before she gives birth. put a LOT of plants in that tank, whether live hornwort or plastic plants. once she gives birth to ALL of them then remove her and raise the fry in that tank.
