so i was am really debating whether to build a rack for my snakes and leopard gecko. my electric bill is getting larger and its some what hard to keep humidity and all that consistent. but i really feel that im gonna miss watching them all crawl around? what do you guys think i should do. and right now i only have a ball python, a corn snake, and a leopard gecko that i could keep in a rack, but im planning on getting a few more ball pythons.and what size tub should i use for adult ball pythons? oh, and if i do go with a rack what is better, with lid or without?
