I have two iguanas and they live in the same enclosure together. Quite peacfully actually, which for iguanas is unusual. However, I have a question I need answered before its too late. It's a simple question, and I hope I don't have to "probe" anywhere to find out (in which case I'll just pay a vet to do it ). How do I tell the sex of an Iguana? And... Is it ok for two iguanas of the same sex to reside together?
