I agree with OFL, as long as they're not killing each other, you should let them be. Often, too fat females are harder to embrace so she would have to release some before they get it right. You will have fewer fertilized eggs but you will have fry.
As a note; sometimes they don't get it right and the female eventually releases unfertilized eggs. Sometimes they need more than a day - because I don't use lights, so the female releases unfertilized eggs.
How ever the condition of your pair, there's a bigger chance of getting fry if you let them be. If you take the female out, she might release unfertilized eggs anyway because her eggs should have "ripen".
