We have two iguana children. One male and one female. We are also the third home for them as well. Our boy Latch has a 6ft top cage, and the bottom is an aquarium that is about 60 gallon tank. I am concerned that Latch isn't going to get any bigger, since he had a poor diet before us. He has calmed down a lot now. And prefers my husband over me. Our female, I have issues with because she wasn't tame before we got her. She still whips and tries to bite. She is OK with my hand in the cage handling her food, but to touch is a big nope. We are afraid that we are going to have to get rid of her since she won't tame down. Am I way over my head with her?
