Anji, he's cute!! Desdemona the kingsnake does the same thing-- she lies on that ledge. Well, actually, she's getting too big now so she kind of hangs off it and sometimes falls.
I wonder too if they do smell each other... tell Deejay to stop being such a hussy!!!
Good luck with him... I wonder if the tadpole idea of Udo's would work, if you can find any.
