New Setup..

[STORMS]

Hello Guys and Girls,
I am getting ready to get a 55 gallon tank. I just wanted some help and Ideas. I know the humidity is prob going to be hard to keep up so I am going to put aluminum over half of the screen lid. I have a lot of peat moss from our Chinese Water Dragon setup.(is this alright to use as a substrate in your opinion). I have also seen some other setups with the Rock type backgrounds (what is that) is that the Styrofoam type backgrounds. Yes I have a UTH and Thermo's for cool and hot side. I have a heat lamp to help with heating the cool side to prop. temps. I use a 60 watt regular bulb for daytime. Then I use the moonlight 60 right now but prob go to 75 for bigger tank.. I have some plans to make two identical hides for hot and cool sides. I have fake plants, and some grapevine wood in my current tank, ( I want something bigger for him to move around in if he wants to. He is 4 foot long(about) I have not completely measured him. He is a problem eater(right now on a 3 month fast) going to try and feed today..Any other info of questions that you have on anything I have left out or whatever dont mind to ask. I know a lot of people do not like the idea of a 55 gallon, but it is what I want. So I want to figure it out....Thanks in advance for all the help and comments GOOD or BAD

If he is not eating now, I would not recommend moving him to a larger enclosure.

What size enclosure is he in currently?
Temps?
Humidity?
How are you measuring temps & humidity?
