Black knobbed sawback

Question
Hello,
     I am looking for some info on this specific type of turtle. I am hoping to become a first time turtle owner and was wondering if this is a good turtle for captivity, as i do not want an unhappy turtle? Is there anything i should know about this type of turtle like health problems or extra care for the shell? Also I am trying to find a life expectancy for this species? I had planned to order from turtleshack.com and was wondering if you had any first hand experience with this site and there pets. I read there reviews, but they were all good and i just can't trust that.
Thank you very much for your time and expertise,
                                      Benjamin

Hello please contact a rescue. We are all full and have to reject turtles and really need people to adopt instead of supporting the market.

This is a good site to assist you as well. Please let me know how else I can help you.; http://www.austinsturtlepage.com/Care/cs-bkmap.htm
