Well I'm not sure if he is a New Guinea or Australian however, I don't know if you were able to read my post on the frilled dragon page but we have three. Simi is the oldest. We love them to death. Especially Simi he was our first and he has some health issues right now of which we have been giving him antibiotics that the vet prescribed. The bloodwork shows his organs are good but his white cell count is high. We are just so worried for him. I will certainly look into the book you have suggested. Thank you
