Ok thanks. A few more question: What is the point in 2 of the same hides? Does that serve some purpose? Also you didnt mention if I need to put them each in their own10g or if 20g would be ok for each of them? If I need to bump them down to a 10g, i need to stop and get one on the way from work tonight. As far as the hygrometer, are the dial ones accurate enough or am I going to need a digital one for more accuracy?
