I was wondering why you would want to know the parents size and temperaments? Most people want to see the parents for their colors but l've never heard someone wondering about their size and temperament. Those types of attributes aren't really something that is passed down to the hatchlings. You could have really big or really small parents. They would still produce offspring of random sizes. The majority of hatchling carpets are nippy. If they are it's proper handling that grows them out of it. Temperament isn't a trait that's passed on to the young. It's more of a learned thing with them.
