I just purchased an ultimate set-up from screameleons and was wonder what a good live plant would be to put in there. I would like it to grow relatively fast so that it will be a decent size when I need to upgrade the cage size. The dimensions will be 20"x18"x12" until the Cham is about 9 months to a year at which time I will upgrade to a 48x24x24. Would like it to be sturdy so the Cham is able to climb around on it. Thanks in advance.
