good luck trying to get those acclimated. the last guyanan i had grew to 8 feet plus. beautiful snake that would rear up like a king cobra and if you pissed it off it'll repeatedly strike. after 4 years it decided to rub it nose against the top of the freedom breeder and get mouth rot. i then had to baytril and iodine the snake but it never came around and expired. btw, i only paid $75 for it from outback reptiles back then (~4 years ago). sticking to cb now. much easier....
