I was wondering what substrate to use in my terrarium. do you have to put dravel on the bottom for drainage? Or two types of dirt? Ive hears so many different answers, im confused [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_h_32.gif[/img] It will be sloaping up the back, so i need something that wont give way.
