i just got a pair of chameleons from someone who couldnt take care of them. Im looking into getting larger cages for them at the moment but my question is what can you tell me from the picture about them? I was led to believe she got them at the same time and yet they seem differant.

One is larger with blue and yellow spots and seems a good size. While the other is bright green and brown, a bit smaller but noticably thinner. They both are active, climbing around and even eating. Perhaps they are just differant sexes, or ages?
