Hi,
I own a 7-year old male and female dragon that live together in a 75-gallon tank. My female is healthy, but my male is unfortunately sick for life. I've taken him to countless vets, and none of these many "reptile specialists" here in NY are able to heal him. But that's neither here nor there. He has many different bacteria living inside of him. He sleeps most of the day, can barely see, doesn't have any energy, walks like a drunkard because he can't use his front arms well anymore, no longer mates, but he eats like a champ.
I would like to buy an additional male dragon for mating purposes, so I would have 3 dragons living in the same tank. But, here's my question: Knowing in general that if you put 2 healthy male dragons together they will fight with each other, what would happen in my situation if I bought a new healthy male dragon and put him in the same tank to live with my sick male dragon? Would the new healthy dragon kill my sick dragon, or would he notice that he's sick and decide that he's not a threat? If I had to guess what would happen, I would imagine the new male dragon would try to fight with the sick dragon, but because my sick dragon is too weak to lift a finger, the healthy male would backoff and no fights would occur. But, that is only a guess. Does anyone have any experience with this, or know someone who has? The last thing I would want to do is put my poor sick dragon in a dangerous situation. My parents will not allow another tank in the house, so they would have to permanently live together in the same tank. Any thoughts or suggestions would be greatly appreciated. Thank you for your help. 
John
