I've been thinking about getting a couple snake racks, since I have twenty-three ball pythons not including the babies and juvies. I've always used custom acrylic reptile tanks but they take up a lot of space and snack racks are much more efficient. So I have some questions about them. Basically does anyone know where I can get a snake rack for cheap? I'd like to compare quality snack racks and some cheaper ones too. Also do I have to use heat tape? I know that it's the best form of belly heat to use with a snake rack and that it's recommended but I was wondering if I have to use heat tape or do I have other options? How do you install heat tape or does it come with instructions when you order it? How long does it last? I'd assume that it's like a heat pad and last for a while. Thanks in advance.
