will save some guppie fry cos i was told you could put a net in your tank so when they are born you can takethe female out of the tank while the fry drop through the net
Use a hatchery, or put the female in a tank with lots of floating plants so the fry can hide in there and just remove the mother after the delivery. good luck
A well planted tank is the best way, you'll get almost the same survival rates and the mother will not get stressed, also remember livebearer fry love to hide underneath things, so I suggest you dedicate a corner with lots of plants and some stones (or marbles also work well)..
