I have had my iguana for a day now and it is not eating. His enclosure is 3'x3' I haven't measured him and I dont know how long he is. There is one heat lamp clipped onto the enclosure (it doesn't produce "long range" heat). We are going to put a humidifier next to his cage and we have 2 long sticks in the cage. We tried feeding him but he wont eat! Also, his spikes are flat and loose and at the end of his tail is some type of stump! Please help! What is going on? By the way we got him off craigslist from someone who had him for 3 months and got him from a reptile store as a return. He is a really friendly iguana.
