I have an agrresive breeder male as well so I know not to put him in with a freshley fed female for atleast 48 hrs as well. But some of my smooth love makers I sometimes intro them after about 24 hrs or so. Haven't had any problems with that regimen so far. Not to say it will never happen but. Everyone has there own way to do things and most ppl will tell you that you have to experiment with what works best for you.
