I have a male beardie who's 3 and a half about. He's very mature and has mellowed out.

More than me wanting to take her, I don't think he is fit to own her. I'm hesitant because I don't know how introducing a female into my tank will make the two of them react. He won't offer the tank either so I have no separation. However I have a very large tank
