Well for starters, I highly doubt your male is gonna be fertile. However, if you wanna try anyway place a divider in the tank you want them to do the deed in. Feed em really well and keep the water parameters pristine as possible. Place a piece of slate, rock, pot whatever you feel is best for you in the tank. After 3-4 days of them being together in the tank, remove the divider.(Watch them closely, they may be fine for a few minutes but things can go downhill fast) If things get a little rough, divide em again. Wait a few days and repeat. Once the male accepts the female, all you have to do is wait. This is my method anyway, others might have different approaches. Good luck.
