In my tanks in Texas (I now live in PA) I had relative success with adding extra plants in my tanks and letting nature take it's course. Right now the only occupants of my 10 gallon set-up is Blueberry and her 3 children. So I won't be using a breeding net.
If at all possible give the expectant Mom her own small tank. With my Texas set-up I had a 1 gallon that I used to ensure a decent amount of surviving offspring from "special" breedings. Move Mom about a week before dropping and 24 hours after dropping move her back to the community tank. If you do daily 50% water changes a 1 gallon tank makes an ok temporary home for a 25-50 fry batch of babies. After two weeks they can be moved to a larger tank or if you want they can be added to the community tank. Yes a few won't survive but the strongest, fastest, smartest ones will.

Good luck with your babies.
