Hi mate, no the stephans I got out of a persons bathroom at 3 am. They are nocturnal tree dwellers usually.
The Krefft's can do a bit of a display, but any snake will if you stir them up. My aim is always to handle snakes as gently as possible to avoid them putting on threat displays, it causes them stress. Even just getting scented by red bellies for eg, to me , means that I took too long, was to rough, and should have done it better. But in this game things aren't always simple.
