I'm by no means an expert or even experienced for that matter ... but this year I have made a few attempts for courtship and I'll explain a little about the results.
First of a tip from an experienced friend, introduce the male and give them 1-2 days together (when the female is ready of course - go by the 1-2 shed system).. then take him away for 1-2 days ... repeat this for a week or however long you feel is necessary - you should see them lock up pretty much within a couple hours of introducing during each of those times. The extra visits ensure that the male is doing his job.
With this method I witnessed a couple lockups but did not bother them enough to see the actual hemipenis. I saw enough action from them that I will cross my fingers and wait for eggs after the next shed.
I have also introduced a couple other pairs but nothing positive. One young (small) male is ready and willing to go and will not eat but no girls will accept him. He twitches like crazy but the girls just flick him away with their body. I'll try again every couple weeks or so.
My larger males don't quite seem to be ready yet. Hoping they will go soon because I have some serious plans for them!
