I'm getting a beautiful red iguana baby soon and I want to make sure his enclosure is set up perfectly. Sorry for the repetitive newb questions! - Can I use sand or Eco earth? I've read that you should not use any substrate capable of being ingested to avoid compaction, but does this actually happen or is this a common care sheet misconception? - Should I provide nighttime heating? I plan on providing a UVB/A lightbulb and a heat light during the day and I don't imagine the temperature ever going below 65 in my room. Should I provide a red heat light to keep on constantly and the UVB lamp during day? - I plan on buying collard greens, turnip greens, and butternut squash in a finely chopped mixture as a daily food with occasional mango and of course some variety every week like green beans and others. Does this sound sufficiently supplemental as a daily staple? I'll be buying whole greens and fruits so I doubt I will feed it all before it goes bad. What's the best way to preserve greens and fruit? Thank you for any help and extra information or experience!
