I almost fell over with those figures. I feel you though, these are all expensive hobbies. Fish keeping is much farther along than reptile husbandry. You are probably correct though, this will be cheaper for you, unless you decide to build an enclosure with Nuerergus kaiseri, Dendrobates histrionicus, and Cruziohyla craspedopus. (Thats a really bad joke) I don't even have enough money to set a tank up at school right now. I suppose if I hadn't bought the camera and field hockey stick I would, but thats a whole other thing. Anyways, best of luck. You'll enjoy it.
