Oh, Nickolouse.
Lydia,
I've seen Billy at a few shows. I don't really know him personally, have bought a few things off him, all have done well, but I think one thing I got from him did not thrive. I'd buy from him again.
In the reptile hobby, this is not uncommon. Even captive bred hatchlings can be seemingly perfectly healthy, then just up and die. It's referred to as "failure to thrive."
It's already been covered, but importing Russian tortoises is a thing. Many species are wild caught versus captive bred because turtles are not always prolific. The return on establishing a colony, getting them breeding, producing babies, getting them to the point where they're ready to go, etc. is not cost effective.
OR, on the flip side, they're so prolific in the wild and readily available, that it's just easier to catch them. Try explaining to a novice, that a full grown Russian at $60 is not a better value than a baby captive bred at $130. The general public doesn't see things this way, and despite the moral outrage, that's what expos and this hobby are: a business that serves the general public.
All states have different laws and regulations around this, but when it comes to non-native species, typically, it's hands off.
One last thing: Russians are known to carry a herpes virus. There is nothing an importer/seller/purchaser can do if they have it. It can be fatal, and there's no outward detection, until symptoms appear, at which point, death is inevitable.
It sucks, but these things happen, regardless of who you're purchasing from.
