I've had my beardie, Fred, for about a month or 2 now. I got him from a friend who wasn't taking very good care of him. I think he is about a year old but I'm not sure. A few weeks ago he just started eating from my hand. I was able to hold him and never had any problems with him. The other day my husband tried to feed him the way I do and he got really aggressive and tried to bite him. Since then he hasn't calmed down. Anytime we even go near his tank he puffs up and hisses. If I go really slow and no one is in the room sometimes I can pick him up. But the whole time his beard is black and if I even look the wrong way he hisses. Most days my husband can't get near the tank without Fred attacking. What can I do?
