If they breed right away you can take the female out if they don't you can leave the female in the cage for a couple of days and then take her out for a couple, then repeat a couple of times to make sure she is prego.
yea if you see a successful copulation... thats it. the female can store that sperm for multiple clutches of eggs so putting them back together is not necessary...if you dont see it then just dont leave them together for more than 5-7 days max...previous advice will work also (couple days together, couple days apart)
