Black Throat Monitor questions

I currently have three Tegus but want to expand my collection to include a Black Throat.
I just spent the last two hours trying to find out some specific information. Unfortunately, there doesn't seem to be a lot of specific information out there without specifically writing to the authors of papers written about the species.
My questions include'
What is the size difference between males and females?
How long do they grow? (age)
Sexual dimorphism if any?
General ability to become tame?

There is a lot of information about range, diet in captivity, enclosure size, (6' to having their own room) and ultimate size potential. What is missing is average size in captivity, growth rate and all the above.
Can anyone out there help with this. Any information you can share will be very helpful and much appreciated.
