I'm going to go pick up my new crested tuesday! I'm really excited, however, last round ( a few years ago ) didn't go so hot. I really was ignorant about what geckos needed back then. I have a 20 gal. tank, a few small branches and small logs, and undertank heater (on low, because my house is about 70 degrees), a basking rock, and tomorrow, I'm building a foam backing and making a few ledges for him to chill on. Any ideas/criticisms of this setup?
