1). I'm currently using a chipper bark substrate, however, I read that Iguanas and reptiles in general are very suceptible to bacterial infections. So I've looked everywhere but I haven't found a proper response about the hygiene of the substrate. How often should i change it? However I saw a video which said substrate can be re-used by cleaning. How would that work? Or is it a better idea to just replace all of the substarte. Or should i only pick fecal matter? Please let me know how to properly provide clean subatrate. And also help me with how and how often should the feces be picked.
2) I've been trying to feed my iguana Hibiscus flowers, grapes, mustard greens, amd banana. So far it has only eaten banana, which concerns me since I read that their main diet should consist of the greens, how do i get it to eat the greens?
I'm currentley switching water and food daily, altough I see that it eats fruits, it barely touches the greens. What should I do?
