yes that is an excellent book,i have 3gtps,1emerald tree,excellent snakes,that book has great info and all:clap: awesome greentree you have there!ok well alot of people already have given you some good advise about this topic so i'll keep it short, I currently have 6 GTP's (chondros) they are nothing like a Ball python, if you are truely serious about getting one i strongly suggest reading The More Complete Chondro by Geg Maxwell you can purchase his book from his website at www.finrgtps.com, this book answers every question you have and I honestly do belive that everyone who is even thinking about getting a Chondro should make this book a mandatory read, also as said above getting a ESTABLISHED juvie, or a adult/ sub adult is the best way to go for your first Chondro also it may cost a lil more money but i highly recomend buying from a breeder due to the fact that ones in pet stores like the one you saw is almost always a WC or farm breed, there are alot of good breeders out there i've purchased quite a few from Rico Walder a great guy his web site is www.signaleherp.com. ok well hope this helps some.
