My fiancee has a 3 year old male Green Iguana and it has recently started striking at its own tail while it's in the vivarium. He was recently moved from a smaller vivarium (around 2' deep, 4' wide, 5' high, to a new one, 5' deep, 4' wide, 7' high. But other than that nothing has changed. I was wondering if there is any reason for this behaviour as he's, on occasion getting his tail and drawing blood.
Thanks in advance
Stephen
