Introducing a male to a female

For those of you who breed, how do you go about introducing your males to your females in their tubs? Do the females ever show aggression towards the males?

Most of mine are very calm all the time, if you have a nasty one which I do, I get her to ball up then I put the male in when she comes out I'm gone and she notices its just a boy to give her some company.:gj:

I pull the water bowl then throw in the male..have never seen any aggression

I hear a little Barry White on the CD player makes the introduction go pretty smoothly ;)

I usually just open the females tub, let the male slide on in and close the tub. I do watch for a bit to make sure there are no problem.
