@TDL: since they’re mainly nocturnal, you won’t see much of them during the day. And if you provide them with ample soil to dig through, you might not see much of them during the night, too. ^^ Some of them are picky eaters, quite delicate health-wise, not the friendliest hot snakes and pack some mean neurotoxins. All in all, not your ideal showcase serpentine species, even though they also have their little fanbase, especially among toxicologists.
