these sites might help answer most of your questions. i think the 29 or 55 will last you a little while before you have to make a more appropriate cage for their size. some people say that they are sensitive/delicate like chameleons in reference to stress and handling. you have to work with them because they are known to revert to being "wild". read what you can and determine if a frilled dragon is right for you. they make nice pets though.
