He looks friendly :)
I visited Australia a few years ago and met a wild bearded lizard (I think that's one in the background ? Don't remember the exact names). A family had adopted hom after they ran him over by accident, and his tail was badly crooked so he couldn't really hunt, but he was still happy in his new life ! They gave him crickets and he glided back and forth over the kitchen floor trying to get them XD.
How long have you had them all ? Any special stories to them ?
