That's a beautiful one Chris.
I got mine as neonates and they are quite different then both in color as well as heavily patterned. As the photo shows, my female is probably going to be a red brown but the male is still changing. His background as a neonate was light ashy grey but he's been darkening steadily. He will likely either be a dark grey or maybe black if the darkening continues.
>>I don't understand why these magnificent beasts aren't more popular in the hobby, particularly among Pituophis fans.
I just think they are not available. I know when I got mine that there was a long waiting list for them but the clutch was very male heavy so only a couple of people got pairs. I got my male initially and then got a female many months later.
>>How is the temperament of yours?
The male and female are very different. The male is wiggly but seldom hisses and never bites. I've had the male since birth. The female who I got later arrived as a hissing, spitting, ornery creature. She still puts on a show every time I reach into her cage and still occasionally bites and musks. Her bite is not bad (no worse than a ratsnake) but she's still small and hopefully she'll calm down with time. My male proves that they can be tamed and acclimated particularly if worked with from birth. I've also known some wild-caught adults that were pretty docile.
