Hi Kristen
I produced 2 litters in 03....It looks like my second litter.
How many pairs?....Um, I have about a dozen or so , I've lost track... Plus I kept back a pair from that litter, as it was her first...
They can be quite variable in coloration
I have black and white ones, and also some nice gold ones...
then some in between. Here's a pic of my two most extremes
Oddly enough the black and white one, fathered the gold one.
I never probe sandboas...Female conicus have almost No tail, it's really short, and males evert and have claws...Get Mr. Ank to pop it for you.. I think it's a male. Look closely and see if it has widdle claws!

...One tip... these guys need to be hot to have an appetite..(85-90F)
