Its not so much the cost, its more that I have to wait til I get paid wed.. I want to get what I need that is the best quality... I did read the care sheet and it really helped, I will have to read it a few more times to retain ALL the info in it along with getting books, and to answer a question, I have ReptiBark in the bottom..One thing I did read is that I should do a FULL tank clean every 6months or so, got it off the internet, is this true or will it just stress Twinkle out? I also wouldn't mind getting something to cover the back and one or both sides on the tank.. What would be the best thing to use and would I put it on the inside or outside of the tank? I'm thinking the outside just so it wont mess with the atmosphere of the tank.. I really do appreciate all the feedback I'm getting, I really do just want to have the best environment for Twinkle that she can have...
