so i have this wooden tank with plexiglass sides that vi use for bearded dragons...about the equivalent of a 180 gallon...and
i have been using repti-carpet as my substrate. i want to switch to sand--or crushed oats? is that what it is? where do you get that stuff?--but should i get a liner? like some plastic something? where would i get something like that? something that would fit right...
