my new terarium im planning on building around six foot high and two and a half feet by three and a half to four and a half base. is this too big. hes gonna have all the adequite stuff like a little cave in the wall. in addition his driftwood jungle gym, lots of fake plants which i ordered from a local store which cut prices in comparison to pet stores a hella lot. and like a humid hide and stuff. all the stuff to keep him happy. but is this too big because i know geckos get stressed with being in too big an enclosure.

thanks guys.
Steve
