Yes, they can live alone no prob. It's just that they can live with others... that isn't very common in chameleons. Henry prefers to be alone and displays very unhappy coloring when he can see other chameleons, even other melleri. He will 'hide' behind a plant when he can see others. He is even shy of the dog..... for obvious reasons. He doesn't care about her when he can see her.... shows no stress. but I noticed he sits behind a plant more when she is in her kennel, in sight. There is no chance for the dog to reach him, hes about 4.5' off the ground and shes always locked up unless someone is home.
