Woo you got a beardie, it will take him a little while to settle in and each beardie is different when getting used to you, some will get used to you very quickly where as others may take a little longer. From what you said about him climbing up your arm I think he's going to be a quick'un, and glad your wifes getting used to him already. His home sounds nice and he sounds like he's loving it. Personally I would feed him outside of him Viv, if you put crickets in there and he doesn't eat them they will just find somewhere to live in the Viv and hide, and then they'll come out at night and drive you insane with the chirping and they'll also nibble on your beardie when they get hungry. You can either get a little container to feed him in or do what I do and just lift him out, put him on the floor somewhere safe, I use my hallway, and then one by one (although sometimes a lot will come out and i'll panic) i just tip them out their container and dust them. Enjoy your beardie
