You should put her in a vase, with the same water level, as your tank. Give the male the whole tank, so he can inspect her, and impress her! Put a half of a styraphom cup in the corner or side of the tank just at the water lvl, for his bubble nest. Make sure you have a plant or two, and a cave maybe incase when you do introduce the female, she can hide if scared. Id wait till the bubble nest was nice and large and the female was nice and plump with eggs to introduce her, maybe a week? or two? (correct me if im wrong breeders). Also i have read a few places that you should seperate the pair for a day or two before the introduction. A "Distance makes the heart grow founder" type deal. Also breeders correct me again! After that you should leave them for a day or so to do the dirty dance! and if to much violence commences it would be wise to take one out so they dont end up killing one another.
Disclaimer: I am not a breeder, yet, i am just going by what i have read, and researched. Just trying to help! :)
