So i am considering getting a RTB...i know there are diffrent kinds, and im doing my research, but i really want to ask people that know about it, from personal experiences. Which would be the best for a semi-newb? I am doing my research, and as long as i can find out what to do, ill take care of it with all my effort...But i dont want a snake that is giant either. A really mellow, well tempered snake...i was thinking columbian.
Suggestions?

Thank you all!!
