That just seems excessively long, but okay.... You make it seem like I'll kill my snake if I put a new one in there, so I guess I kind of have to. So I will. When I get one.
Does the quarantine tank have to be very big? What's recommended size?

And your saying that any snake that's not cannibalistic, I can put in with him. No wandering garters or whatever, but I can put, lets say, a black-necked garter in?
