Wow, that is an awesome idea, DragonFyre14! I always wondered what to do about my filter as well. But most healthy babies wont get sucked into it regardless.
As for the breeding trap, I use them for the first week or two with my fry, sometimes longer since I have some rather...aggressive adults and occasionally older fry will beat up the youngins. I don't put the moms in there unless they don't mind it, most of them do though. I wait until the babies are born, have a LOT of plant cover and hiding places, and then I go after them with a turkey baster. I found that if I didn't catch the babies, I wouldn't even have one survivor. x.x My mothers seem to like killing off all chances for descendants. lol But a lot of mollies wont and lose interest fast after eating a few, it's still sad though. If you get one of those floating breeding traps that have good ventilation, they should b=e fine for the first week or three, depending when you feel comfortable letting them out. Just be sure to put plants in the breeder, it makes less space, but it keeps it cleaner, provides a feeling of safety and security for them. If they are in one of those plastic ones where they can see everyone and everyone can see them, but they can't flee to a safe place, they can stress out and die. =( I don't think it's common, but it completely stopped once I planted my nets. Just a little bit, like those little viney plants that you can free-float.
Also, you can put the mother in there. But wait until you see a baby born. Otherwise she may hold off on her labor and she could get sick. Try to scoop her up WITH the breeder instead of removing her or chasing her around. =) But remember, don't keep her in there more than six hours at the most, those things lack space and the mothers don't like it. It helps to keep the lights out during the birth though. I know, it sucks to not be able to watch sometimes, but it helps mom have a safe delivery. ^_^
I've been breeding mollies for a while, but it's never easy to catch them when they're giving birth as the labor and signs of it can last hours. If you move the mother as she goes into labor, usually she stops it and can take days to resume it. I had a Gold molly do that! She turned out ok though, thankfully. It really is easier to just let her give birth in the main tank and catch the babies later. Keeping the lights out for that will still help mom be less stressed, and the babies have a better chance to escape in the dark.
You could also provide a nursery tank. Ten gallons are nice and roomey for the mothers, and big enough for large amounts of fry to grow comfortably until they're ready for their new homes. I have a ten gallon for that as well, but it ended up being converted into a Kuhli tank. LOL I still let my fry live there as well, and mothers getting ready about a week before they are due. The Kuhli don't mess with them, but I hear they could! If you do that, best tankmates would be smaller cories, they wont hurt the babies and they help clean. ^^;
