Put Lisa's male Heterometrus madraspatensis into a freshy prepared container after putting in my female, for about 15mins they didn't even notice each others presence.
After careful observation i coaxed my female over to the male, instantly he grabbed hold of her metasomas and one of her chela them started juddering and waving his tail around over her. After pulling her around for a bit he got her by both chela and faces touching manouvered her around the tank till he found the flat piece of slate.
After holding her still for a few minutes she jumped up and fiecely chased him of into a corner where he slunked with his tail between his legs.
At that point i interjected and sepatated the pair. This was what was left behind.
Hopefully they have successfully mated but i will try again in a day or so
