Dude, you are joking right?
My iguana only eats lettuce, maybe apple and mushrooms. He doesn't seem to be taking to much. Any ideas as to why?
Have you read any literature or caresheets on iguana-care? If yes, why are you feeding it lettuce and mushrooms???
It appears healthy, just shedded.
Reptiles shed no matter what.
I've got a basking light for it, keeping it warm and all, a semi-spacious tank for it too. It seems active, likes to sun itself. But its eating habits are pretty skimpy. Are iguana supposed to eat a lot at once? Or is this normal?
Do you have a full-spectrum light also? They do need that ye know. And what's with the semi-spacious tank? Why would you keep it in a cramped place? Eating habits are skimpy probably because it is living in a cramped place, has a horrible diet, probably has internal parasites, and probably lacks the proper UV lighting as well.
Either you found the basic "Don't Do" things on the list and posted them for kicks, or you're way off the right track.
Visit this website, and read a few threads on this forum to get an idea on what to do, and what not to do.
