You can not dominate a iguana in breading season, you will end up in hospital. As the other member said give him a green teddy, towel etc. he will use it. But, it does not stop him being out of his mind and aggressive. He needs space and he will rub against the glass until the season is over. In the wild they go and look for a mate and that is what he is currently doing.

Handle him with caution and have a towel ready to protect yourself.
